Scope

This part of GB/T 22159 details a method for measuring the low-frequency translational dynamic stiffness of elastic supports under specific preload conditions. When the output end of the elastic support is blocked, the experimental method of measuring the dynamic stiffness through the force and vibration at the input end is called the driving point measurement method. The stiffness obtained by measuring the displacement (velocity, acceleration) and force at the input end is called the driving point dynamic stiffness. Only in the low-frequency range, when the driving point dynamic stiffness and the transmission dynamic stiffness are equal, can this method be used to determine the dynamic stiffness of elastic supports.
