This article is based on the definition of static friction force in Coulomb friction theory, through the finite element simulation of the friction process of the friction pair model between the electrohydraulic block brake lining and the brake disc, the friction stress of the friction pair under critical radial slip under different radial pressures is obtained. Saint-Venant’s principle and the definition of frictional stress are combined to calculate the corresponding maximum static friction and braking torque. Finally, the braking performance of the brake is affected by the coefficient of static friction, and the law that the coefficient of static friction is affected by environmental factors is further discussed. In this paper, the simulation evaluation of the braking performance of the electric hydraulic block brake through simulation experiments has a certain reference for the evaluation of the friction braking performance of the electric hydraulic block brake.
