Simple and Unified Way of Elasto-Plastic Dynamic Analysis

Summary: This article investigates the vibration characteristics of a hydraulic power injection machine and designs a two-degree-of-freedom mechanical model to improve research on the mechanism of the Plastic Hydraulic Injection System (PHIS). Experimental investigation and analysis are conducted to explore the instability speed and critical stick slip (SS) speed of the system. The numerical simulation results of this study will aid in the design and development of the PHIS mechanism.
