△ ax=MAX (a0x:aTx)-MIN(a0x:aTx)；
△ ay=MAX (a0y:aTy)-MIN(a0y:aTy)；
△ az=MAX (a0z:aTz)-MIN(a0z:aTz)；
3rd, △ a, △ a=△ a are calculatedx+△ay+△az。
4th, carry out eccentric judgement：
△ a ＜ △ a_limit1 → bias is little, lower step dehydration action；
△ a >=△ a_limit1 → bias is big, and stopping is shaken loose；△ a_limit1 are critical eccentric corresponding acceleration
Value.
Instantaneous acceleration △ a as shown in Fig. 3 (a)-(c), obtained by different biasx、△ay、△az, it is various inclined
The heart passes through the test being repeated 20 times.As shown in figure 4, large eccentricity, the middle eccentric and corresponding accekeration of small eccentricity have
Certain discrimination.It can be seen that the method that the embodiment of the present invention is proposed is feasible.
