Optimization design method of marble pressurizing mechanism

The invention discloses an otimization design method for a marble pressurizing mechanism. The method comprises the following steps: establishing a process force transfer function model and a return force transfer function model of the marble pressurizing mechanism; selecting different marble groove inclination angles and friction coefficients to form combinations, and enabling each combination to correspond to one preliminary design scheme; calculating process reinforcement coefficients and return reinforcement coefficients of the multiple groups of preliminary design schemes; according to the design requirement of the control force, determining the value range of a return stroke reinforcement coefficient; selecting the initial design scheme which simultaneously meets the value range of the return stroke reinforcement coefficient and has the maximum process reinforcement coefficient as the optimal design scheme; and performing dynamic simulation analysis on the marble pressurizing mechanism, calculating an er
