摘要
针对绞磨机辅助拉尾绳装置的轻量化问题,结合装置的刚度和强度要求,提出了一种基于响应面法的优化设计方法。通过对绞磨机辅助拉尾绳装置进行参数化建模和静力学分析,将辅助拉尾绳装置的关键结构尺寸作为设计参数,以整体质量最小为目标函数、最大等效应力和最大变形量为约束条件,采用中心复合设计法建立响应面模型,并对响应面的拟合程度和设计参数的灵敏度进行分析。基于响应面模型迭代寻求最优解集,以获得辅助拉尾绳装置的最优设计参数。经优化设计后,辅助拉尾绳装置的质量减小了29%,且工程验证表明,辅助拉尾绳装置整体轻便高效且工作可靠,达到了预期的应用效果,由此验证了所提出的优化设计方法的可行性和有效性。研究结果可为同类型工程装备的结构优化设计与实际应用提供理论支撑和技术指导。
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.
