Optimization design of auxiliary tail rope pulling device for winch mill based on response surface methodology
Aiming at the lightweight problem of auxiliary tail rope pulling device for winch mill,an optimization design method based on response surface methodology is proposed in combination with the stiffness and strength requirements of the device.Through the parametric modeling and statics analysis of the auxiliary tail rope pulling device for winch mill,the key structural dimensions of the auxiliary tail rope pulling device were taken as the design parameters,the minimum overall mass was taken as the objective function,and the maximum equivalent stress and maximum deformation were taken as the constraint conditions.The response surface model was established by the central composite design method,and the fitting degree of the response surface and the sensitivity of the design parameters were analyzed.Based on the response surface model,the optimal solution set was iteratively sought,and the optimal design parameters of the auxiliary tail rope pulling device were obtained.After optimized design,the mass of the auxiliary tail rope pulling device was reduced by 29%,and the engineering verification showed that the auxiliary tail rope pulling device was light,efficient and reliable,and had achieved the expected application effect,which verified the feasibility and effectiveness of the proposed optimization design method.The research results can provide theoretical support and technical guidance for structural optimization design and practical application of the same type of engineering equipment.
