基于结构功能衍生系数的桥式起重机金属结构优化设计
Optimization design of metal structure of bridge crane based on structural function derivative coefficients
摘要
Abstract
Crane is one of the eight special equipment,the rationality of its structural design is crucial for the safe operation,quality improvement,and efficiency enhancement of the equipment.Therefore,an optimization design method of metal structure of bridge crane based on structural function derivative coefficients was proposed.Firstly,the interpretive structure model was used to accurately describe the interactions and influence relationships between different parts of the crane,the structure complexity of the crane was analyzed to identify and optimize the parameters that had a significant impact on the strength of metal structure of the crane.Secondly,based on the finite element simulation,the structural function derivative coefficients were combined with fitting functions to find the optimal combination of design parameters.Finally,a 300/100 t-30 m bridge crane was taken as an engineering example,and the mass of the whole crane was reduced by 2 035.113 kg through simulation,and the effectiveness of the proposed method was verified.The optimization design method of metal structure of crane based on structural function derivative coefficients solves the problem that the complex interactions between various parts of crane is ignored in the traditional optimization method,and can realize the lightweight design of metal structure on the basis of ensuring the safety of crane service.关键词
