Vibrating roller and driving cab vibration reduction system thereof

Abstract

The invention provides a driving cab vibration reduction system of a vibrating roller. An acquisition device is used for acquiring vibration information of the vibrating roller; the vibration information comprises vibration frequency information and vibration amplitude information; a control device is used for sending vibration reduction control signals according to vibration amplitude of the vibrating roller when vibration frequency of the vibrating roller is in the resonant frequency region of a driving cab; a power source device is used for supplying power to an electrorheological vibration reduction device; according to the vibration reduction control signals, output voltage of the power source device is proportional to the vibration amplitude of the vibrating roller; under the action of an electric field, electrorheological liquid of the electrorheological vibration reduction device generates an electrorheological effect and damping; and under the action of the damping, resonance of the driving cab is attenuated. The invention also provides the vibrating roller which uses the driving cab vibration reduction system. The vibrating roller can effectively attenuate the resonance of the driving cab of the vibrating roller, so that the driving comfort of the vibrating roller is increased, and the service life of the vibrating roller is prolonged.

Description

technical field [0001] The invention relates to the technical field of construction machinery vibration reduction, in particular to a cab vibration reduction system of a vibratory road roller, and a vibratory road roller using the cab vibration reduction system. Background technique [0002] A vibratory road roller is a construction machine that uses vibration to compact the road surface. During operation, the vibration motor drives the eccentric block to move, thereby driving the steel wheel to vibrate to achieve effective compaction of the road surface. However, the above vibration will also cause vibration The roller itself, such as the cab, produces more significant vibrations. [0003] In the prior art, in order to reduce the vibration of the vibratory roller cab, rubber blocks are generally installed at the suspension between the cab and the frame, and the rubber blocks are used to isolate the vibration of a certain frequency range, which can reduce the vibration of th...

AI Technical Summary

Problems solved by technology

[0004] Based on the dynamic frequency change of the vibration motor during the vibration loading or unloading process of the vibratory roller, the use of rubber blocks cannot effectively attenuate the resonance phenomenon of the cab, so that the driving comfort cannot be guaranteed, and the strong resonance also affects the mechanical system and electrical components in the cab. The system has a lot of damage, which reduces the service life of the vibratory roller
