Youshan Hou, Yufeng Wu, Zhongtian Xie, Tao Xue · 2021
Taking a four-wheel modular unmanned platform as the research object, 1/4 suspension mathematical model is established and the suspension characteristics are analyzed, modular platform of simulation model is established based on recurdyn, the riding comfort of the modular platform is simulated, and the passability of several modular platform after articulated combination is simulated. The results show that the root mean square of the centroid acceleration of the modular platform is 0.3g at a speed of 100km/h, and the suspension performance meets the requirements of the platform. Passability is at least doubled when multiple modular platforms are hinged together, and performance is improved accordingly as the number of modular platform combinations increases.
