摘要
阐述了对拓扑优化结果进行可制造化处理需要遵循的一般过程及基本原则,对大客车车身骨架拓扑优化结果进行了可制造化处理.建立了新车身骨架结构。经过验算,在保证结构强度刚度的同时,新结构与原结构比质量降低了37%,算例表明处理方法的可行性。
Introduces the general process and basic pricinple which should be followed when doing manufactured treatment for topology optimization ,makes manufactured treatment of topology optimization for bus body frame,establishes new body frame structure.Through test calculation,at the meantime of ensuring the strength stiffness of structure,the quality of new structure reduces 37% compared with original one,the test calculation proves the feasibility of treatment.
