摘 要:基于虚拟样机技术,用ADAMS/ATV模块建立了某型履带车辆的紧急制动动力学模型。通过实车的行驶试验和紧急制动试验对模型进行了VV&A验证,结果表明所建动力学模型在反映履带车辆行驶及紧急制动动力学行为方面能够满足工程分析的需要。将其作为分析平台,对履带车辆进行了紧急制动动力学仿真分析,分析了3-6档平均车速下紧急制动的动力学响应;并通过紧急制动仿真实验得到了履带车辆的制动特性图。
Abstract: Based on virtual prototyping technology, emergency braking dynamic model of a certain tracked vehicle was established by means of ADAMS/ATV software. By travel test and emergency braking test of the tracked vehicle, VV&A of the emergency braking dynamic model was carried out and its credence was proved. Using it as a simulation base, emergency braking dynamic simulation analysis of the tracked vehicle was carried out. The emergency braking dynamic responses at mean velocity of 3-6 gear were analyzed and braking characteristic curve was obtained by emergency braking simulation test.
