汽车制动性能是衡量汽车安全的一个重要指标,它反映汽车在行驶过程中制动的能力。目前国内普遍采用两种检测方法:①试验台检测法;②路测法。由于路测法在测试过程中会受到路况、天气、驾驶员反应能力等客观因素的影响,故这种方法有一定的局限性。试验台检测法可采用平板式制动检验台和滚筒式制动检验台。着重讨论滚筒式制动检验台检测方法的设计与优化。
Car braking performance is an important indicator of vehicle safety, which reflects the car’s ability to brake during driving. At present, two kinds of testing methods are commonly used in China: ① test bed test method; ② road test method. As the road test in the testing process will be subject to road conditions, the weather, the ability to respond to the driver and other objective factors, so this method has some limitations. Test bed test method can be flat brake test bed and drum brake test bed. The design and optimization of testing methods of drum brake inspection bench are mainly discussed.
