Finite Element Analysis Of Carrier Frames Of QTJS160T Railway Cranes

This thesis employs FEA software ANSYS to analyze and carry research on the structure of QTJS 160T railway crane's carrier frame.Through the powerful stuucture anslysis ability of ANSYS,the thesis creats the FEA models of carrier frame,outriggers and pins seperately and has them combined. The carrier frame structure 's intensity is analyzed. Nonliner contact analysis is applied to the contact position of carrier frame,outriggers and pins.The computing results of the thesis shows that QTJS 160T railway crane's carrier frame has met the intensity requirements. The local stress of the contact position of carrier frame,outriggers and pins is presented. The dangerous positions of the carrier frame are pointed out. The thesis forms a theory base for the design and improvement of the carrier frame. Several improving methods are presented. Finally,the thesis provides the idea on the structure analysis of carrier frame to make the future design and analysis more reliable and accurate.
