摘要
为了提高车身定位焊点选取的准确性,文章对焊点仿真建模的各项参数进行了灵敏度和相关性研究,给出了焊点参数对一阶模态影响因素的定量分析数据;采用hyperstudy及OptiStruct软件进行了定位焊点的位置选择方法研究,给出了在规定节拍下的多个零件组焊的最优焊点分布矩阵,结果表明:(1)焊点直径是影响一阶模态最重要的影响因素;(2)采用焊点离散优化设计的方法可以对定位焊点的选择提供设计依据。
In order to improve the accuracy of GEO Welding Spot selection, the sensitivity and correlation of various parameters of Welding Spot simulation modeling are studied, and the quantitative analysis data of solder joint parameters to the first-order modal influence factors are given;the method of selecting the positioning solder joint is studied by using hyperstudy and Optistruct software, and the optimal solder joint distribution of multiple parts under specified beat is given The results show that:(1)Welding Spot diameter is the most important factor affecting the first-order mode;(2)The discrete optimization design method of Welding Spot can provide design basis for the selection of Welding Spot.
