摘要
以煤矿装卸用35t门式起重机为研究对象,首先采用许用应力法和有限元方法对其结构进行校核分析,再利用有限元软件建立起重机结构优化的数学模型,得出轻量化设计结果。通过对优化前、后结果分析一致得出,基于许用应力法设计出的门式起重机,若采用一阶迭代优化方法进行优化,在轻量化方面具有较大改进前景。
35 tons gantry crane of coal mine is chosen as the research object. First of all, its structure is analyzed by using the allowable stress method and finite element method respectively. Then, the structure of the crane mathematic model is optimized. The lightweight design results are obtained. By comparing the optimization and tradition results, container crane has large improvement prospects in lightweight design by using optimal method of the first order iteration, which based on the conventional stress method.
