| 摘 要： | 对某型伺服机构系统压力脉动量大的原因进行分析,确认为油泵、高压管路、溢流阀之间存在频率特性的耦合现象,激发溢流阀发生谐振.针对频率耦合的特性,提出在高压管路上安装节流块的措施,试验验证表明方案简单有效,系统压力脉动量由改进前的4MPa降低至0.8MPa左右.

| Abstract: | The reason for the large supply pressure fluctuation in electro-hydraulic servomechanisms was analyzed, and the frequency coupling was found among the oil pump, the high-pressure pipeline and the relief valve, which caused the resonance of the relief valve. According to the frequency coupling, a throttling block is installed in the high-pressure pipeline and the pressure fluctuation of the system decreased from 4MPa to around 0.8MPa. The method is proved to be effective |
