DatCAM Designs and manufactures Test rigs according to user requirements. Mud Block Test Rig - Used to test the performance of Gearbox with simulation of harsh environment. Reliability is essential in aviation. It is all the more important to use high-tech test equipment in the development, approval and series testing of safety-relevant components in the gearbox.

Power consumed and connected load is only to the extent of frictional losses expected to be less than 30%.
Proprietary loading technique is employed, which ensures Infinite control of loading under dynamic conditions from remote operator stations, which can be analogue or digital.
Bi-directional loading of transmission at full power levels.
The loading being electronic, is amenable for automatic closed loop feedback control. Therefore, the torque developed can be continually monitored and automatically corrected against deviations due to changes in temperature and external disturbances.
The driving power is monitored by reaction torque sensor.
PC based system associated with the test rig facilities testing of transmission for endurance in the desired loading pattern. The site conditions of the vehicle can also be simulated in the test rig under the transient load test conditions.
The control system continually tracks the speed at the torque valve and controls the synchronous speed of the motor to maintain it marginally below the driven speed. The braking torque is precisely settable on the magnetic particle torque valve. The torque thus transmitted through the torque valve reflects on the AC motor, tending to drive it beyond the synchronous speed and thus acting as an induction generator, providing an easy means of regenerating the braking power back into the system. PLC based system are offered to automatically control the sequence of operation and monitor the test parameters.
The present in-line torque transducer is used to continuously monitor the braking torque.
Dynaspede 3 phase AC tachogenerator, suitably positioned on the test bench, is used to monitor/measure the speed. Oil circulation and filtration arrangement with quick acting hydraulic connectors is used for circulation of oil to the test gearboxes. Two transmissions can be tested together.
