In allusion to the frame of a light truck, by the iSIGHT for optimization platform and ANSYS for strength and stiffness calculation platform, with frame mass minimum for objective function, the parameters of the optimal thickness of the frame parts is sought and the optimal solution is obtained by using the first-order optimal design method with the premise of the frame strength, bending stiffness,...
In allusion to the multi-piece leaf springs of a truck, its standard multi-objective optimization model was established. Taking multidisciplinary optimization software iSIGHT as a platform, using the non-dominated Sorting Genetic Algorithm (NSGA-II) based on Pareto optimal concepts, seek for the optimal structural design scheme for multi-piece leaf springs of the minimum total quality and minimum...
In allusion to the frame of a certain semi-trailer, through adopting ANSYS software, its stress response, modal response and random vibration response were calculated with FEA method under various load cases. The finite element fatigue analysis was carried out in the form of load spectrum, as well as fatigue life and the stress strain variation laws of the vehicle frame under dynamic loads have been...
It is significant to study the structure safety of thin-walled vessel under thermo-solid coupled load. In allusion to a thin-walled vessel of failure receiving low-frequency and high-temperature thermal shock and pressure load, direct coupling model, temperature-related material model and Finite Element Method (FEM) were applied to calculate the response of transient temperature field and transient...
