在已有的普通悬架螺旋弹簧设计系统的基础上,以减振器侧向力作为侧载螺旋弹簧的设计目标,应用有限元方法进行结构优化设计。利用C++Builder编程工具,借助有限元软件,将此优化算法程序化,自动生成ABAQUS有限元模型,包括六面体网格自动生成、边界条件自动施加等,并通过后台调用ABAQUS求解器完成侧载螺旋弹簧的有限元分析。同时系统还能够进行侧载弹簧的精确建模,实现了侧载弹簧的优化设计。
Based on the existing common suspension coil spring design system, the finite element method is used to optimize the structure design based on the fact that the lateral force of shock absorber acts as the design target of the side-mounted coil spring. Using C ++ Builder programming tools, this optimization algorithm is programmed by means of finite element software to automatically generate ABAQUS finite element model, including the automatic generation of hexahedral mesh, automatic application of boundary conditions and so on, and calls the ABAQUS solver through the background to complete the side loading Finite element analysis of coil spring. At the same time, the system can also carry out the accurate modeling of the side-mounted springs and realize the optimal design of the side-mounted springs.
