通用桥式起重机腹板加高的力学分析

Mechanical Analysis on the Web Heightening General-Purpose Overhead Crane

结合有限元分析和理论计算,对一台为增加额载而加高腹板的通用桥式起重机进行研究,得出起重机的变形及受力状态,以及理论计算的修正方式。

Base on the finite element analysis and theoretical calculation,the deformation and stress state of a general-purpose overhead crane which the web have been heightened with the purpose of increasing load rating is analyzed,and the modification manner of theoretical calculation is demonstrated to be available.
