【Abstract】 The parameterized model of the shearer traction mechanism is established based on the curve parameter equation.Based on the finite element analysis and kinematic analysis results of the shearer traction mechanism,the experimental design of the control parameters affecting the mechanical performance of the shearer traction mechanism is carried out. The design point updates the parameterized model and performs finite element dynamic analysis to obtain the control parameters with greater influence and establish the relationship between the control parameters and the response results. The response surface model of the traction mechanism is constructed based on the control sample parameters. The MOGA algorithm is used to optimize the response surface model and achieve the optimal design of the shearer traction mechanism. The verification results show that the optimized traction mechanism shows better carrying capacity and stability than the unoptimized traction mechanism.更多还原
