轻型柴油车排气系统路谱采集方法
摘要: 排气系统是整车上的关键零部件,用于处理尾气有毒物质达到净化尾气的目的,同时排气系统也是一个比较庞大的零部件,特别是满足国六法规的排气系统部件更加复杂,比如GPF,DPF,SCR等等,系统的重量也增加了不少,对于系统的耐久也提出了更高的要求。
Abstract: The exhaust system is a key part of the vehicle, which is used to treat the toxic substances in the exhaust gas to achieve the purpose of purifying the exhaust gas. At the same time, the exhaust system is also a relatively large part, especially the exhaust system which meets the national six regulations is more complex, such as GPF, DPF, SCR, etc., and the weight of the system has also increased a lot. It also puts forward higher requirements for the durability of the system.

整车厂在汽车上市前,对产品所能承受载荷的了解是非常重要的,因此要进行道路载荷数据采集(RLDA)的测试,通过获得车辆在实际试验场或公路中行驶的载荷信息,为整车台架道路模拟试验提供目标信号输入,用于车辆开发中的设计和仿真分析。
