轻型汽车道路行驶阻力的测量与模拟

摘要

文章介绍了汽车道路行驶阻力的测量原理、底盘测功机模拟原理和惯量模拟原理；对欧美日三个标准体系中的道路行驶阻力测量方法进行了介绍，以实例对三个标准体系下计算的道路行驶阻力进行了验证和对比。结果表明，三种测量方法所得道路行驶阻力基本一致。%Introduced the principle of simulation and measurement of road load and inertia on the chassis dynamometer, and introduced the measurement method of road load in America, EU and Japan standard system. Verified and compared the calculation results of road load between three standard systems. The re-sults show that the road loads were obtained by the three methods is consistent.
