Abstract: A robust parameter design and optimization of handwheel shoe brake linkage for electric mine locomotive are studied,with genetic algorithm (GA) and Monte Carlo simulation used.Firstly,the kinematic model of linkage is established while the braking process of handwheel shoe brake linkage is analyzed.Secondly,the kinematical model of handwheel shoe brake linkage for electric mine locomotive is established based on the revolving pair clearance model.Finally,with the objective to satisfy the lowest mean error and standard deviation of shoe brake distance,taking the linkage length for the design variables and the revolving pair clearance and contact angle and machining error for noise factors,the model of robust parameter design and optimization for handwheel shoe brake linkage of mine electric locomotive is established,and the parameters are optimized.The result shows that the absolute error of shoe brake distance reduced by 15.4%,and the standard deviation of shoe brake distance reduced by 28.6%.The uncertainty of shoe brake process can be significantly reduced without raising the manufacturing precision of linkage.It has important significance in the design quality of handwheel shoe brake linkage.

Key words: robust design, linkage, braking system, electric mine locomotive
