遵循力学原理的结构设计准则（１）（六）杨文彬（南京化工大学）１引言力是机械设计中最基本最重要的物理概念。机械结构形式千差万别，但其功能几乎都与力（包括力矩，下同）相关：力的产生、转换、改变、传递。构件在实现其力的有关功能的同时自身不可避免地要遭受力的... Structural Design Principles Following Mechanics (1) (6) Yang Wenbin (Nanjing University of Chemical Technology) 1 Introduction Force is the most basic and important physical concept in mechanical design. Mechanical structures vary widely in form, but their functions are almost always related to forces (including moment, the same below): the generation of force, transformation, change, transmission. Components in the realization of its function of the relevant force itself inevitably be subjected to force ...
