利用 ANSYS Workbench 对新型连续旋转液压伺服关节整体进行模态分析,得到3阶振型状态,同时对关节关键部件叶片组和定子进行静力学分析。结果表明,连续旋转液压伺服关节的一阶模态频率为138.63 Hz,在该频率下变形最大的外壳体最大直径处为整个关节的薄弱环节,但该处不会发生共振；叶片的薄弱环节为叶片上部的1/3处,定子的薄弱环节为定子曲线大圆和小圆的过渡曲线处,但这两处的最大应力都小于其材料的屈服强度,故可认定该关节的设计具有可行性。

Modal analysis of new continuous rotary hydraulic servo joint was carried out by using the software ANSYS Workbench and the third order vibration modes of the joint were derived.Mean-time,a statics analysis for the vane group and stator of the joint was performed.The results show that the first order modal frequency of the joint is 138.63 Hz,at which the location with the maxi-mum diameter where deformation is the largest is the weakest point of the joint and yet resonance will not occur there.The weak point on the vane is at the upper one-third part of the vane and the weak point of the stator is on the transition curve between the great circle and the small circle,but the max-imum stresses on both these points are less than the yield strength of the material,which suggests that the joint design is feasible.
