摘要

桥式起重机与门式起重机是使用量最大的起重设备,在设计门式起重机时有必要对其结构动态特性进行研究。以某厂生产的L型门式起重机为例,利用有限元法,通过模态分析得出前六阶固有频率及振型,通过谐响应分析得出对L型门机动态特性影响最大的固有频率,以该阶固有频率为指标,对其结构参数进行动态灵敏度分析,通过分析获得对结构动态特性影响较大的参数,在一定程度上简化了优化模型,为该门机结构的动态优化奠定了基础,并为其他同类结构的动态设计提供了参考。

Abstract

Bridge crane and gantry crane are the equipments which are the most widely used in lifting field,and it is necessary to study its dynamic characteristics when the gantry crane is designed. Taking the L type gantry crane as an example,with the help of finite element method,the crane’s top six order natural frequency and vibration mode were obtained by modal analysis,and the frequency biggest impacting on the dynamic characteristics of crane was obtained by harmonic response analysis,then taking the frequency as index,the dynamic sensitivity analysis of its structural parameters was carried out. In the dynamic sensitivity analysis,the parameters which affect dynamic characteristics of the crane structure more greatly were obtained. By the way,the dynamic optimization model can be simplified. The results provide the basis for the further optimization of the structure and the reference for the dynamic design of other similar structures.
