Steering Durability Test Rig (SP-02-04XX) 

BiSS Steering Assembly Test System evaluates manual and power steering assemblies for durability and performance at frequencies up to 50 Hz. The tests performed are in accordance with JASO C 717, IS 13476, JASO C717 and IS 14269.

A servo hydraulic torque motor, two linear actuators coupled with customized grips and transducers are mounted on moving blocks and accommodate specimens of varying length that are subjected to lateral and steering loads. The whole system is integrated onto a free standing self reacting T-slotted table.
