Adaptive damping nonlinear spring-variable damping system and mobile platform system

A mobile platform system, characterized in that:

• it comprises the following components:
• a mobile platform;
• and
• an adaptive damping nonlinear spring-variable damping system arranged on the mobile platform;
• the nonlinear spring-variable damping system comprises the following components:
• an oil cylinder accommodating damping oil;
• a piston, accommodated in the oil cylinder and movable in the first direction along the oil cylinder to make the damping oil flow, having a central axis extending in the first direction;
• at least one connecting rod, connected to the piston, a non-zero angle formed between the central axis of the connecting rod and the piston;
• at least one first spring, arranged in a spring cylinder along a second direction perpendicular to the first direction, the spring cylinder being fixed to the mobile platform and further provided inside with at least one slider that can move in the second direction along the spring cylinder, the first spring having one end connected to the slider and the other end fixed to the spring cylinder, the connecting rod having one end connected to the slider and the other end connected to the piston;
• a second spring arranged in the oil cylinder along the first direction, having one end fixed in the oil cylinder and the other end connected to the piston;
• and
• a damping adaptive adjustment device, configured to be able to adaptively change the flow resistance of the damping oil according to the vibration of the mobile platform, so as to control the system damping;
• wherein the connecting rod and the first and second springs are capable of subjecting the piston to a nonlinear spring force.
