On the early stage of PS development, it is required to evaluate the
dynamic performances and durability under actual road running conditions
without vehicles, such as speed, ups-downs and steering motions. These
testing systems have various features to simulate the actual road-load
forces, which are unique and reliable.

●Steering Column Test System
The durability of steering column can be performed by reproducing
an actual load condition, which consists of rotation and torque and
the position of input and output.
