Abstract
According to the requirements of automotive performance evaluation standards, a typical quarter vehicle suspension model was established, and the correlation between the suspension model transfer function and the vehicle performance evaluation criteria was analyzed. Because the current lack of a standard bench of car suspension, this paper has established a universal and efficient standard bench of quarter car semi-active suspension. The bench is composed of the hardware system part, the sensing scheme and software system part. The bench can not only be used as a passive suspension development platform, but also can be used as a semi-active suspension control test platform. With the technology of Rapid Control Prototype (RCP), a variety of control schemes for verifying the semi-active suspension can be compared to find a suitable control algorithm, which is very significant for improving ride comfort and safety of vehicle suspension. In addition, the bench is equipped with a force sensor on the piston rod of the damper to monitor the real-time output force value of the damper, and to achieve real-time tracking and correction of the control output in the semi-active suspension control test.
