Extensible mechanism damper based on two-rod tensegrity

Abstract

The invention relates to an extensible mechanism damper based on two-rod tensegrity. The extensible mechanism damper comprises a first stretching mechanism and a second stretching mechanism which have the same structure, are parallel to each other and are arranged at a certain interval. Each stretching mechanism comprises a first connecting rod, a second connecting rod and an extension spring, wherein the two ends of the extension spring are correspondingly hooked to the ends, close to each other, of the first connecting rod and the second connecting rod respectively, and fixing blocks are fixed to the ends, away from the extension spring, of the first connecting rod and the second connecting rod. The middles of two long inclined rods are hinged in a crossed mode, a middle hinge point is formed in the middle, and the two ends of each long inclined rod are hinged to the corresponding fixing blocks on the first connecting rods or the second connecting rods in the first stretching mechanism and the second stretching mechanism respectively. One ends of every two short inclined rods are hinged to form a floating hinge point, and the other ends are hinged to the two corresponding fixing blocks on the same side of the first stretching mechanism and the second stretching mechanism respectively. According to the extensible mechanism damper, a large rigidity change is achieved through small deformation, a tensioning mechanism and an extensible mechanism are combined, the stability is high, and the damping effect is good.

Description

technical field [0001] The invention relates to the technical field of damping devices, and more specifically relates to a deployable mechanism shock absorber based on a two-bar tensegrity. Background technique [0002] Most of the existing shock absorbers in the market are composed of compression springs. The compression spring shock absorbers are mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will move repeatedly, and the shock absorber is used to suppress this spring jumping, but the shock absorber is too soft, and the shock-absorbing object will go up and down. Jumping, the shock absorber is too hard will bring too much resistance, preventing the spring from working properly. In the modification process of the shock absorption system, hard shock absorbers are mat...

Problems solved by technology

However, due to mass constraints, as the mass of the object increases, the size and mass of the compression spring will also increase, the force of the compression spring is also limited to up and down movement, and the cost will also increase
