Problems solved by technology

In some special occasions, the rigidity requirements of the hydraulic damper are relatively strict. For the rigidity requirement of the hydraulic damper in one direction, we can achieve it by adjusting the structural stiffness of the hydraulic damper or replacing the working oil, but the hydraulic damper There are strict requirements on the stiffness in the tension and compression directions, so it is very difficult to solve

Abstract

The invention discloses a hydraulic damper with a rigidity adjusting function. The hydraulic damper with the rigidity adjusting function comprises a left pin head (1), a right end cover (2), a cylinder body (3), a piston assembly (4), a piston rod (5), a left end cover (6), a left pin head (7), a first valve group (10), a second valve group (11), an oil storage box assembly (14) and a plurality of oil channels. According to the hydraulic damper with the rigidity adjusting function, a rigidity compensating device is arranged on a piston of the hydraulic damper; the requirement on the rigidity in a drawing direction of the hydraulic damper is met by a method of adjusting the structural rigidity of the hydraulic damper or replacing a work oil liquid, and then the requirement on the rigidity in a pressing direction of the hydraulic damper is met by adjusting the rigidity compensating device which is arranged on the piston of the hydraulic damper, so that the requirements on the rigidity in both drawing and pressing directions of the hydraulic damper are met. The hydraulic damper with the rigidity adjusting function is simple in structure and works reliably, can meet the requirements on the rigidity in both drawing and pressing directions of the hydraulic damper, and has a broad application prospect.

Description

technical field [0001] The invention relates to a hydraulic damper, in particular to a hydraulic damper with a stiffness adjusting device, which belongs to the technical field of electric and electromechanical. Background technique [0002] At present, hydraulic dampers are widely used in the field of anti-vibration and shock absorption. For ordinary hydraulic dampers, their stiffness is mainly determined by the structural stiffness of the hydraulic damper and the stiffness of the working oil. Once a hydraulic damper of a certain specification After the design is completed and the working oil is determined, its stiffness is basically determined. Through theoretical analysis and experiments, it can be known that the stiffness of the hydraulic damper in the tension and compression direction is inconsistent. Generally speaking, the stiffness of the hydraulic damper in the tension direction is higher than The stiffness in the compression direction is much smaller, which is its i...
