摘要:以精密机床的机械谐振响应特性研究为出发点,以电机动子及负载作为两个惯性系统、通过扭转系数Ks作为衔接,对惯性系统的扭转特性进行建模,分析机械谐振特性与上述变量之间的相关特性。给出了一种以扭转系数Ks为基础的谐振系统谐振响应分析方法,建立了数学模型,进一步引申到伺服控制系统的闭环特性,通过MATLAB对不同惯性、扭转系数组合的闭环特性进行频率分析,解构机械谐振发生的机制,并在线性模组的测试中获得验证。

Abstract:On the basis of the research on the mechanical resonance response characteristics of the precision machine tool, this paper takes the motor rotor and load as two different inertial systems, and connects them with the torsional coefficient KS. As a result, the torsional characteristics of the inertial systems are modeled, and the relevant characteristics between the mechanical resonance characteristics and the above variables are analyzed. This paper presents a method of resonance response analysis of resonance system based on torsion coefficient KS, establishes a mathematical model which is further extended to the closed-loop characteristics of servo control system, analyzes the closed-loop characteristics of the combinations of different inertia and torsion coefficient by MATLAB, and deconstructs the mechanism of mechanical resonance which is later verified in the test of linear module.
Key words:torsion coefficient;inertia;elasticity modulus;resonant response characteristics
