Characteristics Analysis and Optimization of Bridge Crane
For double beam bridge crane girder question of metal structure redundancy,extraction to determine the quality and strength of six important parameters and set the scope of the six parameters,design orthogonal test table to calculate its strength and stiffness,to avoid resonance,calculating the natural frequency of vibration,use the algorithm to fit the experimental results,Concluded that quality,strength,stiffness and naturcdl frequency of vibration mathematical equation about six important param-eters,to design a multi-objective optimization mathematical model with the ratio of natural frequency to solid frequency and the mass as the target,and use optimization algorithm to solve,analyzing the results,it is concluded that the mass of the main beam structure is reduced to a certain extent when the stability is satisfied.
