With the development of railway transportation and the improvement of people's living standard, people's idea about time-space have undergone profound changes, there are new requirements " as one of the most important parts of locomotive bogie for railway transportation, it is used to deliver a variety of loads, and the adhesion between wheel and rail to ensure the traction force generated so, bogie frame locomotive is the legs, the structure performance is good or bad, directly affect the locomotive traction power, running quality, wheel-rail wear and train safety. Efficient Trailer bogie development is the key to the development of high power freight locomotive. A type of AC drive freight trailer bogie is fully at home and abroad locomotive development experience of application developed on the basis of design, it adopts the co co axis type, mainly consists of frame, axle, wheel, suspension, two suspension, braking, traction drive transmission, etc.. Development of the bogie has the advantages of high speed, big traction, the technology is advanced and reliable, easy maintenance etc.. To improve the efficiency and quality of the railway transportation in china. Firstly, three-dimensional modeling of the bogie frame drawings in accordance with the modeling software, so that we can have a clear understanding, on the bogie frame structure by three-dimensional map such as: a clear understanding of the beam, beam, suspension components, to lay the foundation for the calculation of the structure analysis. Secondly, the bogie is calculated and analyzed on the strength of a company research, according to the weak link of strength analysis results, check if it meets the design requirements. Then the virtual state, study its strength should be applied to finite element analysis. The results show that, using the finite element method for structure system design has the very strong practical value, the framework can meet the strength requirements. This paper analyses the steering frame and obtained conclusions will turn to further improve the design frame for locomotive, and provide a theoretical basis for further support, at the same time, steering rack and multi-objective optimization lays foundation
