The paper provides a principle analysis of the passive vibration isolator using zero dynamic stiffness,which demonstrates the vibration in the low frequency range is available based on the zero dynamic stiffness principle and the method of passive vibration isolation.

Study on vertical dynamic stiffness and damp of running tire;

Effect of pretension on dynamic stiffness of high-speed angular contact ball bearing

The dynamic stiffness of pre-loaded hollow cylindrical roller bearing is analyzed.

And then the dynamical stiffness is obtained to evaluate the following characteristics of the loading system.

This article uses the control system theory, regards as the overflow valve is a control system, through the establishment of the relational model between hydraulic system pressure and the system current capacity, infers its dynamic rigidity function, then take enhancing the overflow valve the dynamic rigidity as the goal, with the aid of the MATLAB optimized to.

This paper worked on vibration analysis for different type gantry cranes,advanced a se-ries of practical calculation formula about vertical and horizontal dynamic rigidity of gantrycranes,added some calculation methods of the static and dynamic rigidity,enlarged proofingscopes of the static and dynamic rigidity for gantry cranes.

Through the experiment and the related project data,combining with the finite element that simulated the behavior of the bending steel pipe concrete,we can obtain the effect to the rigidity factor from materials and sizes,and get dynamic rigidity of steel pipe concrete structures\' mathematical expression.
