振动压路机液压系统参数匹配不当,会使振动系统存在较大惯性力,导致出现起振高压。瞬间高压会对液压系统和传动系统造成很大的冲击,导致各零部件受损而出现故障,降低机器的使用寿命。对振动压路机的起振高压形成机理进行分析,并从液压系统参数调整、振动轴结构优化、调幅装置结构更改等3个方面研究如何降低起振高压,结果表明:这3种方式均能有效降低振动压路机的起振高压。
Vibration roller hydraulic system parameters are not matched properly, will make the vibration system has a larger inertial force, resulting in a high starting pressure. Instantaneous high pressure will have a great impact on the hydraulic system and transmission system, resulting in damage to various parts and failure, reducing the service life of the machine. The forming mechanism of vibrating roller is analyzed, and how to reduce the starting high pressure is studied from the aspects of hydraulic system parameter adjustment, vibration shaft structure optimization and structure modification of amplitude modulation device. The results show that all the three methods can effectively reduce Vibratory roller vibration starting high pressure.
