三轴旋转体的动不平衡模型的建立

Establishment of dynamic-unbalance model for three-axis whirl object

在分析三轴旋转体的运动学和动力学方程的基础上,建立了旋转机械体的动不平衡模型,得出旋转机械体动不平衡力矩是加速度力矩、哥氏耦合力矩和离心耦合力矩之和的结论。三轴旋转体的动不平衡模型的建立,为消除动旋转机械体不平衡扰动提供了理论依据。

Based on analyzing kinematical equation of thine-axis whirl object, established dynamic-unbalance model for whirl mechanical object. Obtained the dynamic-unbalance torque of whirl mechanical object is the sum of acceleration torque, coriolis coupling torque and eentrifilgal coupling torqlle. The establishment of model gave aeademie basis tbr eliminate unbalance disturbance of whirl mechanical object.
