Abstract

The invention discloses a damping-variable rigidity-adjustable absorber. A spring compression end cover is positioned at an opening of a spring fixing cylinder, and a size of the spring compression end cover is matched with a size of the opening of the spring fixing cylinder. A diaphragm spring is installed below the spring compression end cover, and an outer cylinder of a damper is installed in the spring fixing cylinder. An upper end cover of the damper is positioned at an opening of the outer cylinder of the damper, and a size of the upper end cover of the damper is matched with a size of the opening of the outer cylinder of the damper. The upper end cover of the damper is installed below the diaphragm spring. Centers of the spring compression end cover, the diaphragm spring and the outer cylinder of the damper are provided with through holes in the same size. A piston rod passes through the through holes of three parties. A piston is fixed at the bottom of the outer cylinder of thedamper. The piston rod passes through the piston. The interior of the piston is provided with multiple upwards and downwards through inner channels. The inner channels are installed along a radial direction of the piston. A pole positioning plate is positioned in the inner channels. The interior of the spring fixing cylinder is filled with giant electrorheological fluid. The damping-variable rigidity-adjustable absorber can be used for real-time adjustment of damping and rigidity.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to a shock absorber with variable damping and adjustable stiffness. Background technique [0002] At present, the shock absorber mainly has three modes: passive control mode, active control mode, and semi-active control mode. The shock absorber based on the passive control mode is the most widely used, simple in structure, and low in cost. However, the natural frequency of this shock absorber is not adjustable. When it is the same as the excitation frequency or has a small difference, it can achieve good vibration reduction. Effect; when the natural frequency of the shock absorber is greatly different from the excitation frequency, the vibration reduction effect will be poor or even the vibration will deteriorate. The shock absorber based on the active control mode collects the information of the vibrating object in real time through the sensor to directly provide force to ...
