Consequently, model test and dynamic loading experiment are conducted aside from carrying out field trial laying of rails and observation upon it.

In this paper, the dynamic stiffness matrix method is used to predict the vibration of the crankshaft system and to calculate the input exciting force from the crankshaft to the slide rod.

Then the dynamic ice force researches on both vertical and conical structures in Liaodong Bay are presented, which form the foundation of quantitatively calculating the structural fatigue life.
