Research on Solving Failure Parameters of Self-Piercing Riveting Connection in Vehicle Crashworthiness Simulation
Journal Title: Automobile Technology & Material - Year 2024, Vol 39, Issue 1
Abstract
A Ls-dyna software based self-piercing riveting joint simulation method for vehicle crashworthiness analysis of was proposed in this research. Method of solving failure parameters for self- piercing riveting joint was studied based on the combination of finite element analysis and test in different forced states, thus improving simulation calculation efficiency while ensuring simulation accuracy. Firstly, a refined simulation model for riveted joints was established based on experimental design, afterwards, a simplified simulation model was established using *CONSTRAINED_SPR2. Using the extracted values from experimental and refined simulation results as simplified parameter inputs can greatly improve the calculation speed of the vehicle crash crashworthiness model. Through this study, it is shown that this method can achieve a simulation accuracy of over 90% for the peak failure force of the self-piercing riveting joint through calibration with experimental results, and can be applied to crashworthiness analysis of complete vehicle model.
