The square root of the driver' s acceleration is selected as the estimate index by the estimate way of vehicle' s comfort. The estimate index is minimized by optimization of fore-and-aft suspension' s stiffness and written with corresponding program. In the end, a model of comfort simulation by soitware of Simulink is found, and a temporal simulation for the upper example is applied to guessing the comfort of vehicle.展开更多
文摘In this paper, a planar five-freedom model of whole vehicle is set up and its corresponding sport differential equation is founded. The square root of the driver' s acceleration is selected as the estimate index by the estimate way of vehicle' s comfort. The estimate index is minimized by optimization of fore-and-aft suspension' s stiffness and written with corresponding program. In the end, a model of comfort simulation by soitware of Simulink is found, and a temporal simulation for the upper example is applied to guessing the comfort of vehicle.
