High-energy consumption viscoelastic silicone oil cabin vibration damper

Abstract

The invention discloses a high-energy consumption viscoelastic silicone oil cabin vibration damper, which comprises an oil cylinder, silicone oil, a central shaft, a damping cup, a damping element, a support sheet for supporting the damping element and a spring for supporting the damping cup, wherein the support sheet is clamped at the reducing position of the oil cylinder; the spring is arranged between the damping cup and the bottom of the oil cylinder; the damping cup is fixedly connected with central shaft by a bolt; a damping cup oil opening is formed on the damping cup; a damping material in the damping element is a high-energy consumption viscoelastic damping material; and a tubular stiffener is inlaid in the high-energy consumption viscoelastic damping material to play a role in supporting and protecting the high-energy consumption viscoelastic damping material. According to the high-energy consumption viscoelastic silicone oil cabin vibration damper, the viscoelastic material with high energy consumption is used as the damping material, so that a vibration isolating and damping effect is improved greatly; the central shaft is separated from the damping element, so that the service life of the vibration damper is prolonged greatly; and the high-energy consumption viscoelastic silicone oil cabin vibration damper is very convenient to maintain in the later period.

Description

technical field [0001] The invention belongs to the field of engineering machinery, and in particular relates to a high energy consumption viscoelastic silicone oil cockpit shock absorber. Background technique [0002] Construction machinery and special vehicles are widely used in various fields of modernization. Because the road surface on which construction machinery and special vehicles travel is different from conventional highways, the road surface has large undulations and irregular structures, so it often causes huge irregular vibrations during driving. How to reduce the dynamic response of the cockpit under the impact of bumps is a very important issue. Excessive dynamic response will cause fatigue damage to the equipment inside the cockpit, reduce the quality and efficiency of the operator's work, and affect the health of the operator. [0003] Research on the vertical vibration characteristics of the human body shows that within the frequency range of 4Hz to 8Hz, ...

AI Technical Summary

Problems solved by technology

Therefore, the active control shock absorber has the following disadvantages: (1) inherent time lag problem; (2) continuous energy supply problem; (3) greatly increased cost

The oil injection hole at the bottom of the silicone oil basin may cause leakage of silicone oil during use, which greatly increases the maintenance work in the later period

[0008] Both of the above two patent documents use ordinary rubber as the shock-absorbing material, so the shock-isolation effect is not good

Moreover, the shock-absorbing material is directly connected to the central shaft, which will cause the shock-absorbing material to be in a state of stress and deformation for a long time, causing fatigue damage and greatly reducing its service life
