摘要
以自行设计的连续驱动摩擦焊机推力缸支撑体为例,对其结构进行了设计.应用有限元分析软件对支撑体进行了参数化建模并校核了其刚度与强度.在静力学分析基础上,利用DOE(Design of Experiment)实验设计法对推力缸支撑体的结构参数进行了采样设计,通过灵敏度分析得出了对支撑体性能影响程度较大的设计变量.而后基于响应面模型及MOGA算法完成了支撑体结构优化设计,在保证支撑体满足使用要求的前提下,使其质量减少了16.56%,实现了支撑体轻量化设计.
Taking the continuously driven thrust cylinder support body of friction welding machine as an example,its structure is designed.The finite element analysis software was used to parameterize the support and check its stiffness and strength.Based on static analysis,the structural parameters of the thrust cylinder support body were sampled by using the method of DOE(Design of Experiment),and the design variables with great influence on the performance of the support were obtained by sensitivity analysis.Then based on the response surface model and MOGA algorithm,the optimal design of the support structure was completed.On the premise of ensuring that the support body meets the requirements of use,the quality was reduced by 16.56%,and the lightweight design of the support body was realized.
