| Abstract: | In order to analyze the capability of the radial devices on Zhuan K7 bogie wheelsets to adapt to the product manufacturer error,the track twisting irregularity,and to analyzed the capability to control horizontal motion of wheelsets,theoretical research is made on the stiffnesses in each direction of the integral structure and main components-sub-frame and cross bar.The calculation result shows that the radial devices on wheelsets have fairly high capability to adapt to the product manufacture error,track twisting irregularity,and can provide enough shear stiffness for bogies;The sub-frame and the cross bar have fair good structure vibration features,and can ensure the radial devices in wheelsets to effectively control the horizontal motion of wheelsets. |
| Keywords: | zhuan K7 bogie radial devices in wheelsets sub-frame cross bar structure stiffness modal analysis |
