Taking the multi-stage gear drive system of tower crane as the research object, a multi-objective nonlinear constrained optimization mathematical model for the design concept of high-efficiency and light-weight hoisting mechanism was established and the general expressions of the corresponding objective functions and constraints , Combined with the NSGA-II algorithm to optimize the gear transmission system of the hoisting mechanism, to obtain a number of feasible solutions to meet the actual needs, broaden the designer’s field of vision, further evaluation of the multi-stage gear drive system for the hoisting mechanism And laid a solid foundation for a sound theory.
