基于COSMOS的轮椅减振弹簧有限元设计研究

摘要

The design of wheelchair shock absorption spring mechanism is based on SolidWorks software. The material of components was defined. Through COSMOS software, simulated mechanical by finite element analysis, calculated the mechanical behavior in different material or construction, selected the data and the best spring design program. The method of mechanical design via CAD reduced the correction procedure of mechanical design. After the first step of mechanical de-sign, optimize the mechanical design plan via finite element analysis and the CAD software. The method of mechanical design reduced the step, of design and enhances efficiency.%设计一种无障碍轮椅的减振机构,基于SolidWorks机械设计仿真软件,建立模拟模型.在整体机构设计方案确定后,定义各个零件的材料参数,利用COSMOS插件时其减振弹簧进行有限元分析,计算并分析减振弹簧在不同材料和结构情况下的力学特性,摘取相关所需要的数据,选择更为合理的减振弹簧设计方案.利用CAD软件建模的方法,使机械设计过程更加直观,便于随时调整设计方案.设计初步完成后,基于仿真软件,结合有限元分析的手段,模拟机构实际工况情况,再加以校核优化.该机械设计方法有利于优化机械设计方案,减少校核环节,提高设计效率.
