摘要
根据材料学知识及数学方法分析了贝雷片龙门吊发生的主梁扭曲变形的原因,根据原因提出了加大主梁水平桁架的抗弯截面模量等处理办法,实践证明这种方法是可行的。
According to the knowledge of materials and mathematics methods, the reasons of main beamtwist for belt-trussed gantry crane are analyzed. The measures which increase the cross section area of the lateral truss are presented. Practical prosects show the method is feasible.
