基于乘员损伤的汽车正面碰撞减速度波形优化
Crash Pulse Optimization of Vehicle Frontal Impact Based on Occupant Injury
摘要
Abstract
With the occupant injury indices as target, crash pulse was researched and simplified. And then crash pulse was optimized to provide improved direction for the body to achieve a forward design of body crashworthiness. Aiming at a minibus, an occupant restraint system of the minibus was modeled using mathematical dynamic model (MADYMO) software and validated based on the frontal impact test. The crash pulse was simplified to optimize the deceleration waveform based on the restraint system model. For specific occupant injury indices, the optimal deceleration waveform was gained. In order to improve efficiency, through the design of experiments Kriging approximation model of the occupant restraint system was built instead of simulation model. The results show that the method can realize that the crush space of the front body can be used rationally and provide improved direction and goals for body. The method that is conducive to a forward design of body crash-worthiness has a strong engineering practicability.关键词
