二、汽车列车的制动稳定性汽车列车制动时不发生列车折叠和挂车甩尾等现象的性能称为汽车列车的制动稳定性。产生折叠和甩尾现象是汽车列车在高速行驶制动时造成重大事故的主要原因之一。(一)汽车列车的自由度分析我们将参考坐标系设在牵引车上,坐标原点在牵引钩的中心,来分析挂车相对牵引车的自由度。 Second, the stability of the car train braking Car train braking does not occur when the train folding and trailer tail flick phenomenon such as the performance of the car train braking stability. The phenomenon of folding and flicking is one of the main causes of the serious accidents that automobile trains cause when braking at high speed. (A) Analysis of the freedom degree of the train car We will refer to the coordinate system is located in the tractor, the origin of coordinates in the center of the towing hook to analyze the trailer relative to the tractor degree of freedom.
