Abstract: In order to improve the stability, safety, and trajectory efficiency of hydraulic support, a composite simulation scheme was applied to analyze the modal characteristics and dynamic stress. A multi-objective optimization method was proposed, which can effectively reduce the weight and stress peak while ensuring the stability of the support, and improve the trajectory efficiency of the front end point of the top beam. Through multi rigid body dynamics analysis, the vertical movement of the top beam and vertical pressure of the front connecting rod were obtained. Through finite element analysis, the modal shapes and transient stress variation laws of the hydraulic support were investigated, and the optimization results were validated. A mechanical analysis model was established for the four-bar linkage mechanism structure of hydraulic support, and the dimension combination that satisfies the minimum angular velocity was obtained. The results indicate that the proposed optimization scheme can effectively improve the motion efficiency and dynamic response characteristics of hydraulic supports.
