F-shaped damping type vibration isolator free of harmonic peak and damping module thereof

Abstract

The invention discloses an F-shaped damping type vibration isolator free of a harmonic peak and a damping module thereof. The vibration isolator free of the harmonic peak is composed of a vibration damping module, the damping module and a connecting module; the vibration damping module comprises a hollow internal thread hexagon bolt, an internal thread sleeve and a main spring; the damping module comprises a waist-drum-shaped damping sleeve, an F-shaped damper, internal truncated cone-shaped pressing rings and truncated cone-shaped rubber rings; the connecting module comprises an upper end cover, internal truncated cone-shaped pressing rings, a lower end cover with a cylinder type embossment and a base; the base serves as a main frame of the vibration isolator, the lower end cover with the cylinder type embossment is connected to the lower portion in the base in a threaded mode, and two revolving curved faces are installed on the periphery of the waist-drum-shaped damping sleeve; and the oblique contacting faces of the F-shaped damper and the periphery of the waist-drum-shaped damping sleeve are different. In the F-shaped damping type vibration isolator free of the harmonic peak and the damping module thereof, the damping module is simple in structure, the F-shaped damping type vibration isolator exerts a good centering restoration effect on lateral vibration, and the harmonic inhibiting effect is strong.

Description

technical field [0001] The invention relates to the technical field of vibration isolators, in particular to an F-shaped damping type vibration isolator without resonance peaks and a damping module thereof. Background technique [0002] No resonance peak vibration isolator can effectively suppress resonance, achieve no amplification in the resonance area, and can effectively prevent electronic equipment from being damaged in the resonance area in a timely manner, resulting in performance degradation or even failure of electronic equipment. It has a stable and reliable anti-strong impact. Effectively avoid damage to electronic equipment caused by impact environment, especially military electronic equipment facing complex and diverse impact environment. Once they are subjected to strong impact, they are easily damaged and fail, greatly weakening or even losing the combat effectiveness of weapons and equipment, such as anti-ship The strong explosive shock waves of missiles, und...

Problems solved by technology

[0003] At present, military electronic equipment often adopts a modular shock-resistant peakless vibration isolator. The technology of this peakless vibration isolator has been disclosed in the patent document CN03131862.2. The vibration isolator is divided into a vibration damping spring module, a damper module, and a connection mechanism module. This modular shock-resistant peak-free vibration isolator suppresses resonance and can achieve a certain buffer performance, but this resonance suppression and buffering are mainly Relying on the spring sheet, in the actual use process, the spring sheet is prone to permanent deformation under the strong impact force of the vibration isolator, which leads to the failure of the damper module and becomes a small damping or no damping state. Only the vibration damping spring module It can play an effective supporting role, and loses the original function of no resonance peak and strong impact resistance, and the structure of this resonance-free peak vibration isolator is complicated, and the installation of the spring piece in the damper module is also troublesome, and the entire resonance-free peak isolation The installation or assembly process of the vibrator is cumbersome, which brings great inconvenience to the maintenance and replacement of vibration isolator parts

[0004] Patent No. ZL201520039978.9 in the prior art provides an improved non-resonant peak anti-strong impact vibration isolator for the above technologies. It mainly improves the damper, and is formed in the cavity of the mounting seat for The resonance suppression structure that suppresses the resonance of the vibration isolator can solve the problem of the failure of the damper module in the CN03131862.2 patent, but its overall structure is relatively complicated, which will inevitably lead to a relatively cumbersome processing technology and relatively high requirements for installation. It is not convenient to maintain and replace the spare parts. More importantly, the resonance suppression structure uses a single damping friction ring to cooperate with the damping pressure ring. The damping friction ring wears too much under strong impact force, which affects the damping effect and suppresses it. The rigidity of the damping support for lateral vibration is poor, and the performance of center return is not ideal, which affects the effect of lateral vibration isolation
