摘要：
To solve the contradiction between the transportation and the operation size of a vehicle, we developed a vehicle-mounted platform that has an effective operation area of five times the vehicle area after deployment and meets the requirements of Road Vehicle Outline Size, Axle Load, and Mass Limit (GB 1589-2004). The M-type deployable platform has a cantilevered flip-up and an embedded underdriven deployable mechanism, which effectively reduces the overall cost and complexity of the platform. Concurrently, considering the motion characteristics of largescale and large deflection changes during the spreading and retracting motion, we investigated the characteristics of the rigid-flexible coupling dynamic response of the hinge with clearance to the spreading and retracting mechanism and platform. Finally, on the basis of the results of numerical analysis, the initial driving torque of the spreading and retracting mechanism and the bottom support mechanism were optimized to reduce the disturbance of the spreading and retracting mechanism at the initial stage of the unfolding and after the completion of the unfolding and the elastic vibration of the platform due to the impact collision force of the hinge gap. © 2022, Editorial Department of Journal of HEU.
