商用车驾驶室乘员保护标准对比及发展分析

摘要

The vehicle cab should be able to provide enough living space when collision happened. The connection parts of cab structure and frame must have enough stiffness and strength of distortion to reduce cab deformation effectively and keep driving and riding space. Based on comparison between commercial vehicle eab occupant protection standards of ECE R29 and GB 26512-2011, test methods are analyzed as well as main differences with current standard, and differenct reasons are further discussed.%车辆发生碰撞时驾驶室必须存在生存空间，驾驶室的结构及与车架的连接方式应具有足够的刚度和抗扭曲强度，以有效地减少驾驶室变形，保持驾乘空间。通过对欧洲ECER29和我国商用车驾驶室乘员保护GB26512—2011标准的对比，分析了标准的试验方法，及其与现行标准之间的异同，并进一步探讨了差异原因。
