Research On Trailer Bogie Of Exported Diesel Multiple Unit At Speed Of 160km/h

In recent years, high-speed rail starts to become a "business card" of national image of Chinese public relations and high-speed diplomacy has been an important means of China’s diplomatic activity. China has been able to greatly enhance level and benefit of its foreign trade and economic cooperation in the form of a package of output cooperation of capital, technology, management, equipment and project contracting through outputting decades of successful pattens and advanced technology of the infrastructure construction, so that the host country can also break through infrastructure bottleneckconstrains to achieve substained growth. More importantly, China’s high-speed rail with high quality, low price and product diversity plays an important role in improving overall technical and service level, and enriching category and variety of high-speed rail in the world.Recently, Many Multiple Units have been exported abroad. In view of different national condtions around the world, choices of traction power for multiple units are not the same. Therefore, there is still huge market space and potential in the high-speed rail market all over the world. It is obviously very necessary to develope Diesel Multiple Units.This article is mainly composed of four chapters. Thereinto, Chapter 1 mainly introduces the design background, the present development status of multiple units and the main research contents of this paper; Chapter 2 describes the overall design scheme of bogie and each component; Chapter 3 carries out calculation analysis of bogie dynamics performance, optimal calculation of key suspension parameters and calculation analysis of fault conditions; Chapter 4 describes stability test of bogie and analyzes test data. The research result shows that ithas certain reference valuve through relevant calculation analysis and test analysis, which provides reference for future work.This paper provides a reference for future work with the corresponding computational analysis, test analysis, the findings with some reference value.
