摘要
对调度绞车"锥齿轮—NGW行星轮系—圆柱齿轮"传动系统进行多约束优化设计。以传动系统的整体体积最小作为目标函数,构建综合齿数条件、模数条件、传动比、重合度、接触强度、弯曲强度、轴径条件和结构条件的多约束条件;利用MATLAB中的Fmincon函数进行多约束优化求解,得到设计变量的优化结果和各级传动系统的优化参数,优化后传动系统体积减小32. 59%;基于此,建立传动系统的三维模型和有限元分析模型,通过优化后传动系统的模态分析,验证了优化结果能够同时满足体积最优和稳定性准则。研究结果可为调度绞车传动系统的优化设计提供一定参考。
The multi-constraint optimization design for the bevel gear-NGW planetary gear train-cylindrical gear transmission system of dispatch winch is conducted. The minimized overall volume of the transmission system is regarded as the objective function,and based on this,the multi-constraint condition is constructed,which comprehensively considers the teeth,modulus condition,transmission ratio,contact ratio,contact strength,bending strength,diameter of axle and structure conditions. The Fmincon function in MATLAB is used to solve the multi-constraint optimization. The optimization results of design variables and optimization parameters of all transmission subsystem are obtained,and it indicates that the volume of the transmission system decreased by 32. 59% after optimization. Based on this,the 3D model and finite element analysis model of the transmission system are established. According to the modal analysis of the optimized transmission system,it verifies that the optimization results can simultaneously satisfy the optimal volume and stability criteria. The results can provide reference for the optimal design of the transmission system of dispatch winch.
