摘要

采用正交试验法

在Simufact仿真软件中进行了锡青铜连杆衬套错距旋压试验

以旋压成形后连杆衬套的内径公差及外表面圆度误差为评价指标进行数值模拟

通过灰色关联系数及灰色关联度进行多目标参数优化

得到优化的错距旋压的参数组合以及各因素对评价指标的影响程度。结果表明

影响连杆衬套尺寸精度的参数主次顺序为:进给比>首轮压下比>轴向错距

采用优化后的错距旋压参数可明显提高连杆衬套的成形质量。

Abstract

By using the orthogonal test

the error pitch test was carried out in the Simufact software.The internal diameter tolerance and the outer surface roundness error of the connecting rod liner were simulated.Through the grey correlation coefficient and grey relational degree

the multi-objective parameter optimization was carried out

and the parameter combination of the optimal error pitch and the influence degree of each factor on the evaluation index were presented.Results show that the order of influencing the connecting rod bushing size precision is followed as:feed ratio>first round pressure ratio> axial offset

and the forming quality of the lining sleeve for the connecting rod is obviously improve by using the optimized the offset spinning parameters.
