[0022] Detection Principle: 1) With the half-shaft clamped, the rotary motor uses a set torque output mode, outputting a torque of 4 Nm. This torque is amplified to 100 Nm through a 1:25 reducer and then transmitted through a 1:1 gear set, maintaining a constant torque. The torque is ultimately applied to the flange. When the rotation reaches its limit, the encoder angle X1 is recorded.
[0023] 2) Then the rotary motor reverses direction until it can no longer rotate. At this point, the encoder angle is multiplied by 2 several times.
[0024] 3) Through calculation, the actual arc length of the rotation is L = π*85 / 360*(X2-X1).
