Abstract

The invention discloses a light mechanical molecular spring vibration isolation buffering device and particularly relates to a light mechanical molecular spring vibration isolation buffering device. Amain piston cavity and an auxiliary piston cavity of the light mechanical molecular spring vibration isolation buffering device are connected by a high-pressure hose and a joint, and the cavities arefilled with water. A main piston of the main piston cavity bears load, and an auxiliary piston of the auxiliary piston cavity bears pretension force applied by a spring. The spring used in the lightmechanical molecular spring vibration isolation buffering device is a disc spring. The mechanical molecular spring uses water as a force transferring medium, and the main piston, the auxiliary pistonand the pre-compressed spring are used as force bearing elements. The light mechanical molecular spring vibration isolation buffering device provided by the invention has the characteristics of high bearing capability and low inherent frequency and is suitable for the field of low-frequency heavy load.

Description

technical field [0001] The invention relates to a light-duty mechanical molecular spring vibration isolation and buffer device, which belongs to the technical field of vibration isolation and buffer. Background technique [0002] Vibration is always one of the focal issues in the fields of aeronautics, aerospace, marine and vehicle engineering. Generally speaking, vibration will lead to structural fatigue damage, reduce the performance of instrumentation equipment, and reduce ride comfort. In the field of national defense, strong vibration will affect the survivability and combat technical performance of weapons and equipment. Passive vibration isolation technology is widely used because of its simplicity, low price, and reliability, such as metal spring isolators, metal rubber isolators, rubber isolators, wire rope isolators, air spring isolators, etc. However, the vibration isolation effect of these vibration isolators in the field of low frequency and heavy load often c...
