further, the method can further comprise multi-drive working condition control, and the multi-drive working condition control mode comprises the following steps: the PLC21 is controlled by the measurement and control computer 20 in the experiment table measurement and control system 40, and the PLC21 controls the transducer forward rotation terminal 22 and the transducer reverse rotation terminal 23 of the transducer connected with the driving motor 1 through control voltage signals, so that the driving motor 1 is controlled to reciprocate or move continuously in a single direction.
A method for realizing replacement of a precision speed reducer by adopting a precision speed reducer multi-working-condition comprehensive performance experiment table specifically comprises the following steps: the through holes with different position sizes are formed in the speed reducer mounting bracket 4, when the precise speed reducer needs to be replaced, the speed reducer model corresponding to the position size of the through hole needs to be selected, and replacement is completed through bolt connection.
