A Series Shock Absorber Based on Leaf Springs

Abstract

The invention relates to a flat spring based series damper. The flat spring based series damper comprises a bottom mounting part (1), a plurality of flat springs (2), a plurality of elastic rods (3) and a top mounting part (4), wherein one flat spring (2) is fixed on the bottom mounting part (1); the flat springs (2) are overlapped; every two flat springs (2) are supported through the plurality of elastic rods (3); the flat spring (2) on the top end is connected with the top connecting part (4) under the supporting of the plurality of elastic rods (3). According to the flat spring based series damper, the flat springs are designed, so that the height of a multi-stage series damping system can be greatly reduced, and the applicable scope of the damper can be expanded; the flat springs are connected through the elastic rods, and therefore, the structure of the damper is simple, and the assembling is easy; in addition, the scale of the flat springs can be changed (the quantity of the flat springs and the elastic rods can be increased or decreased), in order to adjust the rigidity of the damper, and as a result, the design is simplified.

Description

technical field [0001] The present invention relates to shock absorbers, in particular to a serial shock absorber based on leaf springs. Background technique [0002] In vibration engineering, as an isolation and absorption device for vibration energy, shock absorbers are widely used in resisting vibration shocks and protecting equipment structures. [0003] Ideally, the lower the stiffness of the shock absorber, the lower the natural frequency and the better the shock absorption effect. Traditionally, shock absorbers are often connected in series to improve the vibration reduction effect by means of multi-stage vibration reduction. However, this series connection method makes the size of the shock absorption system in the height direction larger, which limits its scope of application and cannot be used for height requirements.

Problems solved by technology

Traditionally, shock absorbers are often connected in series to improve the vibration reduction effect by means of multi-stage vibration reduction. However, this series connection method makes the size of the shock absorption system in the height direction larger, which limits its scope of application and cannot be used for height requirements. Harsh use environment, such as shock absorption of sensitive electronic components

[0004] Due to the large size of the traditional series method, there are usually only two stages of vibration damping, and the adjustable range of the total stiffness of the vibration damping system is very small, which brings difficulties to the vibration damping design

When traditional shock absorbers are connected in series, the intermediate adapter plate needs to be designed separately. Although the application of intermediate mass improves the high-frequency vibration reduction effect, it also greatly increases the design complexity.

After searching, it is found that the patent application 200510128866.1 describes a typical shock absorber based on a steel wire rope, which is mainly composed of a first fixed seat, a second fixed seat, and a multi-layer steel wire rope, and the three are screwed together; this design overcomes the helical spring The shock absorber has the disadvantages of small damping and small radial load-bearing capacity, but because the elastic element is a steel wire rope with a large size, the height space occupied by the installation is large, and the height of the two-stage vibration reduction based on its design is larger
