A Shock Absorber That Can Precisely Balance Three-Dimensional Stiffness

Abstract

The invention provides a shock absorber with the accurate three-direction rigidity balancing function. The shock absorber is composed of a steel wire rope shock absorption set and a series shock absorption set. The series shock absorption set is composed of a box sleeve, a sleeve cover, an adhesive elastic module and a centering shaft rod. One side of the steel wire rope shock absorption set in the Y-axis direction is fixedly connected with an external support and the other side of the steel wire rope shock absorption set in the Y-axis direction is fixedly installed at one end of the box sleeve. The other end of the box sleeve is closed through the sleeve cover, the adhesive elastic module is arranged in an inner cavity of the box sleeve and can be deformed elastically in the Y-axis direction, one end of the centering shaft rod is fixed to the center portion of the adhesive elastic module, the middle of the centering shaft rod is matched with the sleeve cover through a shaft hole, and the other end of the centering shaft rod extends out of the sleeve cover and is fixedly connected with a component to be damped. The shock absorber has the three-direction rigidity, the three-direction rigidity is accurately balanced by adjusting the shape and the size of the component, three-direction shock interference is effectively isolated, and compared with a traditional metal shock absorber and a rubber shock absorber, the shock absorber has the advantages of being good in shock isolation effect, low in resonance amplification factor and the like.

Description

technical field [0001] The invention relates to the technical field of vibration reduction, in particular to a vibration absorber capable of precisely balancing three-way rigidity, which is used for vibration reduction of sensors inside a photoelectric stabilization turret. Background technique [0002] The external interference of the photoelectric stabilized pointing system has always been a key issue in the system development process, such as the vibration of the carrier engine, the vibration interference of the environmental control equipment, and the carrier turbulence in a complex environment, etc., will affect the stability of the system image and the accuracy of the aiming. Influence, affecting the operator's accurate identification of battlefield dangers and the effective lethality of weapons and ammunition, especially the vibration interference with high intensity and wide frequency spectrum, may cause the failure of the entire photoelectric stabilization system, an...

However, its biggest shortcoming lies in the poor consistency of the stiffness in the three directions. The test data shows that the stiffness in the Y direction is usually more than twice that of the X and Z directions. For example, in the face of the same type of multi-directional interference, a certain direction of the shock absorber has a better stiffness, which effectively exerts the shock absorption effect, but other directions with a large difference in stiffness must have a poorer vibration reduction effect, and it is easy to The phenomenon of system resonance occurs, so the selection of this type of shock absorber is more difficult
