| 摘 要： | 从弹塑性力学基本理论出发分析了压力校直过程悬臂梁弯曲的力学特性。建立了挠度与载荷之间的关系式。在此基础上,提出通过把载荷p当作中间量建立初始挠度y0与校直行程y的函数关系来解决引线校直过程中校直行程的确定,进而编制了引线校直行程计算VB程序。通过实例计算与校直实验结果的比较,验证了提出的方法及程序具有较高的求解精度能满足自动精密校直工艺的要求。

| Abstract: | The flexural mechanical feature of metal cantilever beam during the straightening process is analyzed and a relation between deflection and curvature is established by the application of the elastic-plastic mechanics.Based on that,the calculation straightening stroke of the straightening process is solved by using p as the intermediate variable between the initial deflection y0 and straightening stroke y.And a VB program for the straightening stroke's calculating of lead wire is designed.By comparing the re... |
