High-energy consumption viscoelastic vibration isolating damper for engine

Abstract

The invention discloses a high-energy consumption viscoelastic vibration isolating damper for an engine. The high-energy consumption viscoelastic vibration isolating damper comprises an upper damping block and a lower damping block, wherein the upper damping block comprises a central shaft, a high-energy consumption viscoelastic material fixed on the central shaft, an upper metal gasket arranged on the top surface of the high-energy consumption viscoelastic material and an upper support arranged on the lower part of the high-energy consumption viscoelastic material; the lower damping block comprises the high-energy consumption viscoelastic material, a lower metal gasket arranged on the bottom surface of the high-energy consumption viscoelastic material and a lower support arranged on the upper part of the high-energy consumption viscoelastic material. According to the vibration isolating damper, the high-energy consumption viscoelastic material can increase damping ratio of a structural system and enhance a vibration isolating effect of a low-frequency area, so the vibration isolation and vibration damping effects are achieved.

Description

technical field [0001] The invention belongs to the field of engineering machinery, and in particular relates to a high-energy-consuming viscoelastic shock absorber for an engine. Background technique [0002] Construction machinery is widely used in various fields of modernization. Since construction machinery often operates in a state of rapid variable speed and load change, the engines of construction machinery are mostly high-horsepower and high-power engines. The vibration caused by these high-horsepower and high-power engines is also huge. If these vibrations are not effectively and reasonably controlled, they will be transmitted to the frame and then to the main structure of the construction machinery, which will cause relatively serious damage to the construction machinery. Large vibration, this kind of vibration not only reduces the service life of construction machinery, but also greatly endangers the health of machine operators, affecting the work efficiency and ...

AI Technical Summary

Problems solved by technology

At present, the commonly used damping device is mostly made of ordinary rubber, which only has the effect of shock absorption, but not the effect of shock isolation, so the effect of controlling vibration is still not very good.
