| Abstract |
|
The wedge type rail clamp compresses with small clamping force at first, and with large clamping force when the wind speed increases because of the wedge working. At this time in order to display the wedge working, the rail clamp slips along a rail. If the supporter is not installed in the rail clamp when the wind speed increases more and more, the structure will occur overload which leads the structure to fracture. So the supporter has to be installed in the rail clamp. The proper position of this supporter is determined by the initial clamping force and the wege angle. Therefore in this study we adopted 5-kinds of wedge angle as the design parameters, and carried out the finite element analysis, in order to analyze the relationship between the initial clamping force and the position of supporter in the wedge type rail clamp. |
