In order to make the design of the traveling crawler in planting hole forming device of transplanting machine for rape meet its performance,and ensure that the whole structure is compact,according to the structure and design characteristics of traveling crawler,a mathematical model of optimization was established.The design variables include the structure parameters and installation positions of the driving wheel,the tension pulley and the bearing wheel,and the thickness of driving base-band and bearing plate.Taking the shortest length of the traveling crawler as the target,optimization analysis of the mathematical model with the fmincon function of Matlab was conducted.Nonlinear finite element analysis of the traveling crawler after finished the 3D modeling and virtual assembly of the track was done.Optimized parameters are as follows:the total length of traveling crawler was reduced from 3 904.2 mm to 3 642.3 mm,about 6.7% reduction;the height of machine was decreased about 56.9 mm,and the weight of traveling crawler was reduced by 7.9%,which effectively reduce the engineering cost.The results of field trial show that the optimized traveling crawler meet work demands of the planting hole forming machine,which proves that the optimization scheme is feasible.
