Piezoelectric-actuated nanopositioning stages commonly employ flexure amplification mechanisms to enlarge output displacement and are widely used in optical measurement, micro and nano manufacturing, and other precision engineering fields. However, existing methods still have limitations in computational efficiency, hi...
To address the insufficient output displacement and local stress concentration of compliant grippers used in polarizer attachment and flexible film handling, this paper proposes a multi-objective optimization method for a three-stage displacement-amplifying compliant gripper using NSGA-II. A parametric model was establ...
Non-pneumatic tires (NPTs) eliminate the need for internal air pressure and avoid common issues such as puncture or pressure loss. In this work, a hybrid NPT that combines cellular and spoke supports was designed and evaluated. A three-dimensional model of the proposed tire was developed and analyzed by using finite el...
Purpose. To conduct multi-criteria parametric optimization of a new type of forging device spring package to reduce the total package height and number of springs without increasing mass, taking into account design constraints and uncertainty of the preload deformation and working load. Research methods. Methods of ma...
Corrugated paperboard is prone to significant deformation in the thickness direction, and it is this characteristic that endows it with excellent energy-absorbing cushioning performance. However, most existing equivalent homogenization methods for corrugated paperboard are based on plate theories that assume constant t...
Modular steel construction offers significant advantages in fabrication efficiency, installation speed, and structural adaptability; however, the performance of inter-module connections remains a critical concern, particularly under lateral loading conditions. This study aimed to evaluate the mechanical behavior and st...
