试验台飞轮系统优化设计与有限元分析

摘要

基于惯量模拟对同步器换挡耐久试验台的飞轮系统进行了结构设计,在满足转动惯量要求的前提下,以飞轮质量最小为目标,利用最优设计理论对飞轮结构参数进行了计算.基于优化结果,通过有限元仿真对飞轮系统进行了静力和模态分析,仿真结果表明优化的结构满足飞轮系统的强度和动力学要求,能够安全可靠的工作.%The structure of the flywheel system on test rig of shifting durability of synchroniser is designed based on the inertia simulation.Satisfied with the request of the inertia moment,structural parameters of the flywheel system are calculated to minimize the flywheel mass using optimization theory.By the static and modal analysis using the FEM,the simulation results indicate that the optimized structures can meet the demands for the strength and dynamics of the flywheel system,which leads to safe and stable work.
