Multi-objective Topology Optimization of a Mining Dump Truck Frame
摘要
Abstract
In order to guide the structural design and optimization of frame of a first domestic mining dump truck, the local failure or damage of this component were concerned,which was due to terrible running road and overweight. Based on SIMP(solid isotropic material with penalization) method and variable density method,topology optimization of frame was studied, where both the stiffness and first—order frequency were regarded as optimization objectives under multiple loading conditions. Compromise programming method was utilized to define multi —objective topology optimization function of multi —stiffness and frequencies. Compared with stiffness and frequency of original frame,it is shown that the performances of optimized structure are definitely improved. Which is extremely helpful to design and optimize frame of mining dump truck so that it is able to work well under terrible situation.关键词
