摘要:
为了解有轨电车与汽车碰撞兼容性特点，进而为保护汽车乘员和改善两者的碰撞兼容性问题提供思路和依据，采用有限元仿真分析方法对有轨电车与汽车常见的10种碰撞工况进行仿真分析。研究发现：有轨电车对汽车具有很大攻击性，两者存在严重的碰撞兼容性问题，改善其碰撞兼容性的关键是解决两者的碰撞刚度匹配问题；当碰撞速度大于30 km/h时，汽车乘员有危险，有轨电车应在平交道口适当降速运行。
Abstracts:
In order to understand the compatibility characteristics of collision between tram and car, and further provide ideas and basis for the safety of vehicle occupants, improve the collision compatibility, the finite element method is used to simulate 10 common collision conditions of tram and car. The research results show that trams are very aggressive to cars, serious incompatibility exists between them. Therefore, the key of improving the collision compatibility is to solve the collision stiffness matching between tram and car. When the collision speed is greater than 30 km/h, the car occupants are bound to be in danger, so the tram should reduce the running speed properly at the grade crossing.
