Auto crash simulation test sled
汽車模擬碰撞滑車試驗裝置On the basic of a great of literature reading and research on safety of side impact of the car, according to requirement of ece r95, applied madymo6. 2. 1 software, established simulation model of side impact of the car, researched the relationship between side rigidity of the car and passenger injury in side impact, which showed that during first impact the bigger side rigidity was, the more advantaged protection for the car and passenger in a definite range, and which drew a conclusion that the most serious part of passenger injury was pelvis during first impact. then detailed the substructure model by defining bodies, joints, contact types and contact characteristic, researched some improvement approach for side safety of the car, and then analyses a particular case, that was to say to fix vehicle door bar fender on between inner and outer plate of the vehicle door, analyzed the influence of passenger injury when the bar fender was fixed on different position, the result showed that the passenger injury was less when the bar fender was fixed on the height of vehicle door decorate bar. finally, a set of tests were performed, contrasting the simulation result with the test, analyzed the influence of the side rigidity of the car to passenger injury, which showed the test
本文在對汽車的側面碰撞安全性進行大量文獻閱讀和研究的基礎上，按照歐洲ecer95側面碰撞乘員保護法規的要求，應用多剛體動力學軟體madymo6 . 2 . 1 ，建立了汽車的側面碰撞模擬模型，研究了汽車的側面剛性對乘員損傷的影響，結果表明在「一次碰撞」中，在一定范圍內汽車側面剛性越大，越有利於汽車和乘員的保護，同時得出結論，即在「一次碰撞」過程中人體損傷最嚴重的部位是骨盆;然後通過定義各剛體、鉸鏈、接觸類型以及接觸特性，對該模型進行子結構細化工作，研究了加強汽車側面安全性的若干改進措施，並進行了一個特例分析，即在此模型的車門內外板之間安裝了車門防撞桿，分析了當車門防撞桿安裝在不同位置時對乘員損傷的影響，結果表明防撞桿位於車門裝飾條的高度時，對乘員的損傷較小;最後進行了一組側面碰撞試驗，通過試驗和模擬結果的對比，分析汽車的側面剛性對乘員損傷的影響，表明試驗和模擬結果是一致的，從而證明了模擬模型的有效性以及模擬結果的正確性。Using the simulation method coupling of multi - body and finite element, the simulation model of frontal impact, side impact and car - pedestrian impact of a certain type of vehicle is established by madymo software, and the comparative analysis of impacting performance of the vehicle fitting with or without this equipment is made out. the simulation results show that the vehicle fitting with this equipment has better damping and energy absorption performance. combines with frontal bumper air bag, not only the injury to the occupants and pedestrians in crash accident can be decreased further, but also the damage to the vehicle can be decreased
3 .採用多剛體與有限元耦合的模擬計算方法，利用madymo軟體建立了汽車正碰、側碰及與行人碰撞的模擬模型，對有無該裝置時車輛的碰撞性能進行了比較與分析，結果表明安裝有該裝置時車輛具有更好的緩沖與吸能特性;結合前保險杠安全氣囊技術，不僅可以進一步減少碰撞事故對乘員及行人的傷害，而且可以減少碰撞事故對車輛本身的損壞。By simulation to crash energy absorption machine equipment, foundation curves to realize deceleration curves of the regulation test and auto crash test are acquired, and number and cost of test can be reduced
