Mechanical Structure Design of the Aircraft ASD Control Isolation Control

Table 4

First six-order modal analysis results of operating isolation mechanism.

Order	Natural frequency (Hz)	Vibration mode characteristics
1	71.14	Except that the roller is not affected, the rest rotates around the -axis
2	221.45	The pitch axis is locally bent along the -direction, and the handle rotates around the -axis
3	466.70	Except that the roller is not affected, the rest is twisted around the -axis
4	969.49	The roller rotates around the -axis, the pitch axis bends along the -direction, and the handle rotates around the -axis
5	1149.70	It is mainly due to the expansion deformation of the roller and its rotation around the -axis
6	1210.30	The pitch axis bends in the -direction, the roll axis rotates around the -axis, and the handle rotates around the -axis
