Research On The Structure Of 200km/h Electric Locomotive Bogie Frame

With the rapid development of national economy and advance in science and technology, the widespread application of high speed train in China has become reality. As one of the most important necessary part of high speed locomotive, the bogie frame's property has significant impact on running quality and safety of locomotive. On the basis of making detailed finite element analysis and accessment of it's mechanic property, the design theory of frame has been probed. Such work is of momentous significance in pushing forward the development of high speed train in China.The large-scale and general finite element software-ANSYS is employedto analyse the frame of locomotive in speed of 200km/h by FEA. According to the analytical results, the static stress and fatigue stress of frame are checked in the light of current criterions. At the same time, the mode analysis of frame is made and the results are analysed. Based on studying the present situation of codes for design on bogie frame, the deficiencies in current codes are pointed out and the necessity for formulating code for design and calculation of bogie frame is also discussed. The conclusions drawn in this thesis can provide reference for design and calculation of bogie frame.
