以某工程自卸车为研究对象，运用ADAMS/Car软件建立包括柔性车架、轮胎、驾驶室前后悬架、车厢、发动机和转向系等子系统的工程自卸车刚柔耦合模型。根据国标建立了H级路面，在相同的路面、车速和载重下，分析了前悬架板簧刚度对自卸车平顺性的影响，为自卸车平顺性的研究提供了一些参考。%Taking an engineering dump truck as the research object, using the ADAMS/ Car to build a rigid flexible coupling model which includes flexible frame,tires,cab,front and rear suspension,trunk,engine and steering subsystems. According to na-tional standard,established class H road and analysis the front suspension leaf spring stiffness’ influence on the truck ride com-fort,and provide some reference for the research of the dump truck ride comfort.
