摘要
关于发动机减振器优化设计问题,在橡胶减振器的设计中,大多采用经验设计和试验修正的方法,效率低下且无法应用于形状复杂的橡胶减振器设计。针对上述现状,分析了橡胶减振器的静、动态特性和参数选择与设计,并以Python为工具,基于ABAQUS二次开发技术完成了橡胶减振器参数化优化设计系统及橡胶减振器动态刚度计算系统。前者实现了在满足指定三向静态刚度要求下,对形状复杂橡胶减振器的尺寸优化设计;后者实现了在指定预载及激励下,橡胶减振器动态刚度的计算。既满足了形状复杂橡胶减振器的设计要求,且整个设计计算过程自动快速,有效地提高了设计效率,缩短了产品开发周期。
Recently, the experience design and test correction method are used mostly in the design process of rubber shock absorber, but this method has low efficiency and can not be used in complex shape of rubber shock ab- sorber design. In this paper we analyzed the rubber shock absorber of static, dynamic performance and parameter se- lection and design, and took Python as the tool, the secondary development of technology based on ABAQUS was ued to finish the rubber shock absorber parametric optimization design system and the rubber shock absorber dynamic stiffness calculation system. The former was realized to satisfy specifies three static stiffness requirements and the size of the rubber shock absorber optimization design; the latter achieved the rubber shock absorber dynamic stiffness cal- culation in the designated preloading and incentive. It meets the complicated shape rubber shock absorber design re- quirements and the whole design calculation process is automatic and fast.
