Study on Energy Stability of Automotive Door Slamming Simulation Using Abaqus/Explicit

Energy stability is considered as a significant engineering challenge during transient event simulations using Abaqus/Explicit dynamics. This study focuses on the simulation of automotive door slamming impact to analyze the factors influencing total energy stability systematically. Contact pairs, general contacts, and nonlinear connection elements are identified as factors having the most substantial impact on energy stability. Additionally, the study proposes a novel Explicit dynamics modeling method conducive to achieving total energy stability. By addressing the issue of energy stability in Explicit dynamics, this research contributes to enhancing the accuracy of transient dynamic analysis.
