Abstract:

Entangled porous metallic pseudo-rubber (EPMPR) is formed by interlaced helical metal wires, and its unique structure can convert mechanical vibration energy into heat, providing significant damping effects. This study innovatively proposes a method for constructing the elastic hysteresis curve of EDMMR at the physical level, and decomposes and extracts the hysteresis curve using virtual manufacturing technology (VMT). Based on finite element numerical calculation nodes, this study constructs the stiffness curve of EPMPR's series-parallel structure, and considers the contact behavior of EPMPR, especially under high-temperature conditions, through dynamic evolution analysis of discretized numerical models of spatial contact behavior, further studying its damping hysteresis behavior. Specifically, this study also proposes for the first time and comprehensively analyzes the dynamic and static parameters of EPMPR under different temperatures and loads, providing in-depth insights into its mechanical behavior and energy dissipation mechanisms. Experimental results demonstrate that under the complex topology structure and thermomechanical coupling, the elastic hysteresis curve of EPMPR can accurately predict its damping characteristics under different high-temperature environments, providing a theoretical foundation for EPMPR's application in advanced equipment and structural extreme environments.
