| Abstract: | The bar linkage of turbine throttle valve is mainly composed of onevalve stem,one connecting rod and one piston rod.The dynamic model for the systemwith the valve stem perpendicular to the connecting rod is established by Kane's methods.Especially,it is on the condition that the connecting rod makes an angle of 45 degrees with the valve stem and is 106 inches long that the numerical solution of this model approximates to that of the model for the system with the valve stem and the connecting rod being coaxial in a normal engineering design. |
