Abstract
This article systematically demonstrates the method and process of using the combination of "virtual test field+CAE finite element calculation+nCode designlife" virtual simulation method to conduct durability analysis of cargo truck frames based on real vehicle load spectra. Taking a certain light-duty truck as the research object, 9 external connection points on its frame were taken as load collection points. The load data of the relevant test points were obtained through real vehicle collection and virtual test field load extraction. The stress life calculation was carried out using the Design life and Glyphworks modules of nCode software, and the life calculation results obtained by the two methods were compared. The results showed that the calculation error of the virtual simulation method was within an acceptable range, and the method was feasible.
To address the problems of long cycle, high cost and insufficient precision in traditional durability verification of automotive steering knuckles, a passenger car steering knuckle was taken as the research object. Combined with measured road load spectrum, virtual iteration, reverse modeling and finite element analysis, systematic fatigue life analysis and reliability verification were conducted. A high-precision geometric model was established via 3D scanning and reverse engineering, and its validity was verified by free modal test. Virtual iteration based on Adams-FEMFAT-Lab co-simulation was used to extract the fatigue load spectrum of key connection points. Fatigue simulation under multiaxial random loads was completed in nCode DesignLife based on the quasi-static method and Miner’s linear cumulative damage theory, and the results show that the fatigue life mileage of the steering knuckle is significantly higher than the design index. The integrated digital method proposed can provide technical support for fatigue reliability verification and intelligent manufacturing of key chassis components.

This study proposes a simplified approach usable on standard office computers for analysis of controlled demolition of buildings that have completed their service life. In this method, proposed as an alternative to complex simulations requiring high-end hardware, the structure is modelled by finite-elements, with load-bearing elements being removed from the system progressively based on blasting sequence. The structure was investigated using non-linear static analysis under its own weight, and it is accepted that the demolition occurred when the global drift ratio exceeded a specified limit value (4% for this case study). The accuracy of this method was tested on the demolition of a 60 m high reinforced concrete silo in Gaziantep. As a result of comparing analysis results with real demolition footage, it was revealed that the proposed method is an efficient and practical tool for predicting the mechanism and direction of collapse of the structure.

This paper addresses the static strength assessment of bogie frames for PE2 (M, U) series industrial traction units used in the mining industry. Currently, a significant portion of the widely operated PE2M and PE2U traction units has been in service for 40-50 years. Given that the manufacturer-specified service life for these units is 24 years, there is a critical need to justify the feasibility of extending their operation to more than double their original design life. The objective of this research is to determine the mean stress of the bogie frame loading cycle. A 3D model of the bogie frame was developed using SolidWorks, and structural analysis was performed via the Finite Element Method (FEM) in Ansys Mechanical. The finite element analysis results indicated a mean Von Mises stress of 63 MPa, and a safety factor of 2.65. Based on the findings, relatively higher stresses were observed in the zones beneath the central pivot plate of the pivot transom. The low values of mean stress, combined with the biaxiality levels, confirm that the bogie frame possesses sufficient static strength. These research findings can be utilized to evaluate the fatigue strength and residual life of the bogie frame, as well as to justify its service life extension.

Amid the rapid development of the new energy vehicle industry, the vehicle frame, as the core load-bearing component of the entire vehicle, plays a direct role in the vehicle’s safety, lightweight design, and power performance through its design and performance. Although research on new energy vehicle frames has matured, issues related to the lightweighting of drive shaft-associated structures and the balance between weight reduction and strength/stiffness still require in-depth exploration. This study focuses on the chassis of new energy vehicles, utilizing Q295 low-alloy high-strength steel. Based on the vehicle’s dimensions and mass parameters, a simplified 3D model was constructed using SolidWorks. Static analysis under bending and torsion conditions, along with a 6th-order modal analysis, was conducted using ANSYS software. Based on the analysis results, optimizations were implemented at both structural and material levels: structurally, the central crossbeam was widened, holes were opened on the crossbeam’s vertical plane to reduce weight, and the longitudinal beam welding process was optimized; materially, Q295 steel was retained in high-stress zones, while aluminum alloy replaced it in low-stress zones. The optimized frame achieved a 15% reduction in torsional stress, a 16% decrease in bending stress, a 2% reduction in torsional deformation, and a 3% decrease in bending deformation. Total mass decreased by 12.7 kg, with both strength and stiffness meeting design requirements. This approach synergistically enhances frame lightweighting and performance, providing technical support for optimizing the overall performance of new energy vehicles.
The empirical approach to rigid pavement design does not fully capture the actual interaction between the concrete slab and its supporting soil layers, even though this aspect determines the long-term performance of the Nusantara Capital City (IKN) feeder access roads that serve heavy vehicles. This study aims to analyze the deformation and soil–structure interaction of rigid pavement using the finite element method through PLAXIS 3D software. The pavement system was modeled as three layers: the subgrade and lean concrete working floor using the Mohr-Coulomb constitutive model, and the concrete slab using elastic plate elements. Material parameters were derived from N-SPT test results and standard empirical correlations. Loading was modeled as four concentrated loads of 53.936 kN/m² representing the four wheels of a truck with a total load of 22 tons, and was simulated through staged construction. The analysis showed a maximum total displacement at the observed node of 0.01776 m (17.76 mm), which remains within the safe limit against deformation failure. These results confirm that the slab thickness designed using the empirical approach is capable of accommodating the vertical deformation caused by heavy vehicle loads, indicating that the numerical and empirical approaches are mutually complementary in ensuring design reliability.

Automobile tire is a vital component of a vehicle. It is the only one that comes into contact with the road surface also. All engine power is transmitted to the tires through the transmission and wheels. Therefore, the range of consumer requirements for tires is quite broad, including safety, comfort, durability, cost, and appearance. Therefore, creating a tire that meets customer requirements at the design stage is a complex and non-trivial task, requiring significant time and financial investment. At "Cordiant" Company this problem is addressed through the extensive use of modern calculation methods and software for computer simulation of both individual tire and tire within a vehicle. Before the widespread adoption of computer technology, tire configuration calculations were based on equilibrium contour theory, which was determined using nomograms proposed by a group of authors led by the prominent Soviet scientist V.L. Biderman [1]. Key tire performance indicators included mileage and durability. Currently, the finite element method (FEM) -- a numerical method for solving partial differential equations arising in applied physics -- is widely used in tire design. Specialized software is used for these calculations at "Cordiant" Company. The input information for the calculations includes tire geometry (profile, material distribution, 3D tread pattern model), material properties, loads, and boundary conditions. The result of the FEM calculation includes displacements, deformations, and stresses of each structural component. Processing this information allows the characteristics of the future tire to be determined in terms understandable to engineers. Various models are used to describe the properties of rubber in simulation: Hyperelastic model proposed by Yeoh, which accounts for the nonlinearity of changes in their properties under various stress states [2], and viscoelasticity models. Cord materials are defined by Young's modulus. The first and most important class of problems, upon which further calculations are based, are static problems, including: calculating the structural safety margins, the contact patch shape analysis and contact pressure distribution, and determining the longitudinal, angular, lateral, and radial stiffness of the tire. This data set allows the engineers to obtain initial information about the tire's performance on the road and eliminate obviously unsuccessful options. The set of dynamic simulations includes: the tire hydroplaning, rolling on mud and snow, thermal analysis, and wearing. This group of calculations is quite complex and resource-intensive, but it provides important information about tire's performance under real operating conditions. A new milestone in modeling development has been the use of a test track simulation system, which allows the replication of real road tests through the analysis of the kinematics of multi-mass structures. Most automakers worldwide, as well as tire testing centers, use similar software to optimize suspension performance and vehicle handling precision. To create a reliable, working model, it is crucial to incorporate real data on tire behavior. In collaboration with our partners, we developed a method for estimating vehicle speed during a "double lane change" test. The input information consists of the track configuration and the vehicle's suspension characteristics. "TMeasy", a semi-physical approach (gray box method), was used to model tires within a vehicle. To prepare the "TMeasy" input file, tests were conducted on a specialized Skid-trailer - a trolley that records changes in forces and moments under various rolling conditions. The simulation results and the actual testing on the track showed satisfactory correlation. In conclusion, it can be noted that the development of calculation methods and the creation of a unified digital calculation environment make it possible to: • improve the validity of design decisions; • consider the tire as a whole and address the challenges of developing new products with improved performance; • increase the intensity of development by replacing some full-scale testing with virtual experiments.
