Optimization of Cutting Head Parameters and Mechanical Analysis of Roadheading Machine
Taking EBZ75 cantilever type roadheader as an example,a cutting head parameter optimization and mechanical analysis method of roadheader is introduced.First of all,according to the characteristics of the cutter head of the roadheader,the finite element model of the cutter head is constructed,and then from the cutting angle and the rotation angle respectively,the simulation analyzes the force situation of the single cutter tooth and the whole cutter head,so as to determine the optimal parameters of the cutter head,i.e.,the cutting angle is in the range of 48°~50°,and the rotation angle is in the range of 12°~14°.Through practical analysis,it can be found that the cutting head moment and energy consumption of cutting ratio after optimization of cutting head of roadheader are lower than that before optimization,which indicates that the optimization of the parameters and mechanical analysis are feasible.
