Explain Critical factor in Design of shock transmission unit?

(a) STUs are unidirectional devices for load transmission. If out of plane forces will be acting on the STU, the angular limits of these loads must be determined to assure that the STU can withstand them. Generally ball joints and or additional devices can be incorporated to properly transfer these forces.

(b) For rail road bridges, the traction forces may equal or exceed seismic forces in magnitude and applied many times over the life of the structure.

(c) The corrosion protection for STU is very important. The position rod, in particular, should be protected from environment by a scaled cover able to accommodate the full stroke of the STU.
