Abstract

The hydraulic overload protection system is widely utilized with the advantages of high precision control, suitable for multi-point press and automatic reset. The stiffness of the hydraulic pad is a key factor affecting the corresponding performance. In contrast, the stiffness value of the hydraulic pad and the effects of the pipe length, the thickness and the diameter to the hydraulic overload protection system dynamic response characteristics acquisition have not been studied systematically. In this paper, the methods of theoretical analysis, finite elements, system modeling and numerical simulation were utilized to obtain the change rule of hydraulic pad stiffness and the affecting factor in the dynamic response of the hydraulic overload protection system. The results indicated that the method to obtain the stiffness of hydraulic pad was effective and the hydraulic pad stiffness gradually increased as the pressure increased. The pipe would reduce the stiffness of the hydraulic pad. As the pipe length increased, in the same pressure range, the stiffness of the hydraulic pad was reduced. In addition, the peak level of the dynamic response pressure in the pipeline was affected by the pipe length, the pipe diameter and the pipe thickness. The pipeline diameter had the highest effect on the peak pressure, whereas the pipe thickness had the least effect.
