Abstract: A system for integratedly testing damping performance of a hydro-pneumatic suspension vehicle, including a testing platform and a testing device. The testing device includes a sensor module, a data acquiring and processing module and a testing software. A method for integratedly testing damping performance of a hydro-pneumatic suspension vehicle is also provided. A calculation is performed by a testing software to optimize a sensor configuration. A signal is acquired and transmitted by the sensor module. The signal is acquired and processed by a data acquiring and processing module, and displayed and analyzed by the testing software.

Abstract: Disclosed is a half-vehicle floating device and a half-vehicle position tracking method based on load feedback. The device includes a rack, an active platform, a position-measuring triangle frame and a position-measuring platform. Guide rails corresponding to the active platform and the position-measuring platform are provided vertically on the rack. The active platform and the position-measuring platform are respectively placed on a corresponding rail through a slider. The bottom of the active platform is hinged to a first corner of an active triangle frame through an active slider rod, and a second corner of the active triangle is hinged to the rack and connected to an inverter motor through a transmission device. The bottom of the position-measuring platform is hinged to a first corner of the position-measuring triangle frame through a position measuring slider rod, and a second corner of the position-measuring triangle frame is hinged to the rack.
