Car Interior Design of Topology Optimization Design And simulation Analysis

研究汽车内部拓扑设计优化问题。汽车内部拓扑结构承受的表面压力、重力和均匀负载度在小区域内的波动变化,传统的设计方法为了应对波动,需要采用小区域多衔接点的位置关系进行拓扑设计,造成汽车内部结构发生弯曲和扭转的点增加,导致汽车内部拓扑设计过于复杂,降低了性能。为此,提出基于压差比例优化模型的汽车内部拓扑结构设计优化分析方法。充分考虑汽车内部结构承受的表面压力、重力和均匀负载度,计算汽车内部结构的压力载荷向量,获取承受不同压力的相关函数。根据汽车结构的承压力和压力相关函数,得到拓扑设计的约束条件,获取拓扑结构关系,完成汽车内部拓扑设计。实验结果表明,利用改进算法进行汽车内部拓扑设计优化分析,能够优化不同零部件之间的空间位置关系,降低拓扑设计的复杂性,提高汽车内部拓扑结构的性能。
