连续墙抓斗起重机猫头架结构应力计算与有限元分析

Stress calculation and finite element analysis of cat head like masthead of diaphragm wall grab crane

以某一特定型号的连续墙抓斗起重机为研究对象,在进行受力计算之后,借助Pro/Mechanica软件对猫头架结构进行有限元计算,获取猫头架在受到外载荷作用后的响应情况,并对得到的结果进行分析,对猫头架的设计提出了改进意见。

Taking a hydraulic diaphragm wall grab crane as subject, the paper describes how the structure of masthead is calculated with the finite dement software Pro/Mechanica based on analysis of load on the grab. Furthermore, it analyzes the calculated results according to the response to the different loads and offers how to improve the masthead structure.
