White body stiffness test bench

White body stiffness test bench

The white body static stiffness test bench for automobiles is mainly used for testing the bending stiffness, torsional stiffness, door opening and window deformation of the white body of passenger cars (sedans, MPVs, SUVs, buses, etc.). Under experimental conditions, the torsional stiffness and bending stiffness of the body are assessed. Test the vehicle body under simulated working conditions according to the constraints and load conditions during use.

Reference standard:

Q/CAF01 0300 T-39-2008 "Rigidity Test Method for Vehicle Body Bending (Flexibility)"

Q/CAF01 0300 T-40-2008 "Torsional Rigidity Test Method for Vehicle Bodies"
