Abstract

The invention discloses a nonlinear spring-variable damping system with a self-adaptive damping function and a moving platform system. The nonlinear spring-variable damping system is applied to a moving platform and is characterized by comprising one oil cylinder containing damping oil, one piston, at least one connecting rod, at least one spring and one damping self-adaptive adjusting device; the piston is contained in the oil cylinder, and the piston can move along the oil cylinder to enable the damping oil to flow; the connecting rods are connected with the piston, and the deformation process of the springs is restrained by the connecting rods; and the damping self-adaptive adjusting device is configured to change the flow resistance of the damping oil in a self-adaptive mode according to the vibration of the moving platform so as to control the system damping, and when the moving platform vibrates, the connecting rods and the springs can enable the piston to be subjected to nonlinear spring force. Compared with a linear-damping system, the amplitude of the nonlinear spring-variable damping system is greatly inhibited.

Description

technical field [0001] The invention relates to an adaptive damping nonlinear spring-variable damping system and a mobile platform system. Background technique [0002] During the movement of the mobile detection platform on the structural surface, it will vibrate when it passes through the uneven structural surface. The vibration will have a major impact on the smoothness and stability of the mobile detection platform, which in turn will affect the safety of the detection probe and the accuracy of data collection. Stability and accuracy, so the mobile testing platform must be equipped with a shock absorption system to reduce the impact load on the mobile platform, improve the grounding of the rollers, suppress the beating of the mobile platform, improve the ride comfort and stability of the mobile platform, and ensure the safety of the testing equipment run efficiently. [0003] The characteristics of the spring and shock absorber used in the traditional passive shock abso...
