and direction vibration values of small vibration on up and down direction.

Serial number	Cylinder threshing time/s	direction vibration amplitude/um	direction vibration amplitude/um	Vibration amplitude/um	Vibration phase/°
1	33.61	31	46	55	56.02
2	33.62	36	37	52	45.78
3	33.63	41	16	44	21.32
4	33.64	45	7	46	8.84
5	33.65	49	11	50	12.65
6	33.66	52	26	58	26.56
7	33.67	54	43	69	38.53
8	33.68	57	53	78	42.92

Note. Vibration amplitude was square root of and direction vibration amplitude. Vibration phase was horizontal angle of vibration amplitude and direction.
