【摘要】 在数控强力切削进给伺服系统中,机械传动系统对电气调速系统具有扭矩反馈作用,容易形成机械谐振。机械谐振现象使得机械传动部件的特性参数影响电气调速系统动态特性。文中研究了机械传动系统的阻尼比!mech和惯量匹配系数q对机械谐振的影响,并提出了减小机械谐振影响的补偿方法。更多还原

【Abstract】 In CNC heavy cutting servo system, mechanical drive system has a torture feedback on electrical speed-adjustment system, thus it’s possible to generate the mechanical resonance. The mechanical resonance makes the feature parameters of mechanical drive system influence the dynamic performance of the electrical speed-adjustment system. This paper has studied the resistance ratio and q parameters, and put forward the method to decrease the mechanical resonance influence.更多还原
