摘要
针对机械设计中存在的复杂零件主形心惯性参数计算困难,以及截面形状复杂的零件弯曲强度计算繁杂的问题,在AutoCAD基础上进行了分析和研究,提出了一种机械设计中由复杂结构零件的三维实体模型反求零件的主形心惯性参数的方法。指出了复杂截面弯曲梁的弯曲强度计算方法与步骤。
In the mechanical design,It is difficult to calculate complicated shape machine components＇s main centroid inertia parameter,and cross section complicated shape components＇s bending strength calculation. According to this problem,Base AutoCAD on analyzed and researched,taken on methods and steps by complicated structure components three-dimensional solid model reverse main centroid inertia parameter,and taken on methods and steps proceeding to bending strength calculation to curved beam of the complicated shape.
