Test Rigs

ETA designs and supplies a variety of Test Rigs as per customer requirements. Fatigue TestRigs for Steering Columns

In this machine the column is secured in ‘as-in-vehicle-mounted’ condition and two servomotors are connected to either end of the column. The one on the wheel end runs on velocity mode and the other on torque mode. The column is tested for life at various torques, frequency, and angle of rotation as the test procedure stipulates. There is provision for locking of pinion end of the column. Plotting of graph (Torque Vs angle of rotation) is provided. Other machines for Testing Steering Column are UJ Backlash Testing and Plotting of Hysterisis, Free Torque Testing, Torque to Failure, Key-Lock Testing, and Offset Bend Testing.
