Castigliano Theorem,the paper developes the theorem in solving deformation of known position to a crest theorem in solving maximum deformation of unknown position.
在卡氏定理的基础上,将求解给定位置变形的卡氏定理延拓至求解未定位置最大变形的极值定理。
The stress concentration position and maximum deformation value can thus be determined at the moment of initial moving of the connecting rods and the structure of rods is optimized,so that deformation of the rods in the course of process .
首先阐述了大连杆机构的工作过程,并对硬盒包装机的左机身大连杆的自由度进行了计算,然后运用三维有限元方法分析了大连杆的受力情况,确定了大连杆在初始运动时的应力集中点和最大变形量并对其在结构上加以优化,减少了大连杆的加工和使用变形,保证了大连杆的使用质量。
