Abstract

The invention discloses an air bag type low-rigidity suspension device. The air bag type low-rigidity suspension device comprises an air cylinder, a piston, a pneumatic system and a steel wire rope. The air cylinder comprises a cylinder body, an elastic membrane, a restraining thin wire and limiting support columns. The pneumatic system comprises a rubber air bag, a connecting pipeline, an air storage tank and an air source. The rubber air bag is arranged in the cylinder body, the elastic membrane is arranged in the cylinder body and arranged on the top of the rubber air bag, the bottom of the piston is arranged on the upper surface of the elastic membrane, the air cylinder is suspended in air through the steel wire rope, and the piston tightly presses the upper surface of the elastic membrane under the action of a suspended heavy object and the gravity of the piston. The air bag is additionally arranged in the cylinder body of the air cylinder, the high-pressure gas can be completely closed in the cylinder body, the inherent air leakage problem of a traditional gas suspension device is solved, and accordingly the noise problem caused by air leakage is solved.

Description

technical field

[0001] The invention relates to a suspension device, in particular to an airbag-type low-rigidity suspension device, which belongs to the field of vibration measuring instruments. Background technique

[0002] Low-stiffness suspension refers to the use of a suspension device to compensate the weight of the structure itself at the structural point of the specimen, and can not impose any restraint force, so as to realize the simulation of unconstrained boundary conditions. The most common method used in engineering is mechanical suspension, such as using rubber springs or metal springs. The rubber spring is made of polymer material, the texture is relatively soft, it can achieve extremely low stiffness, and the resistance to transmitting sound is large, so the sound insulation is better, the noise is small during working hours, and it has good air tightness, water resistance and electric resistance. Insulation. However, due to material problems, rubber spring...
