NONLINEAR SPRING-VARIABLE DAMPING SYSTEM HAVING SELF-ADAPTIVE SHOCK ABSORBING FUNCTION, AND MOVING PLATFORM SYSTEM

WIPO Patent Application WO/2022/213561

A1

A nonlinear spring-variable damping system (200) having a self-adaptive shock absorbing function, and a moving platform system (100). The nonlinear spring-variable damping system (200) is applied to a moving platform (1), and comprises: an oil cylinder (6) accommodating damping oil (5); a piston (7) accommodated in the oil cylinder (6), the piston (7) being able to move along the oil cylinder (6) to enable the damping oil (5) to flow; at least one connecting rod (8) connected to the piston (7); at least one spring (9), the deformation process of the spring (9) being restrained by the connecting rod (8); and a damping self-adaptive adjusting device (300) configured to change the flow resistance of the damping oil (5) in a self-adaptive mode according to the vibration of the moving platform (1) so as to control system damping; wherein when the moving platform (1) vibrates, the connecting rods (8) and the springs (9) can enable the piston (7) to be subjected to nonlinear spring force.
