1、文献翻译先进转向架测试系统的发展附录Advanced the development of test systems bogieSummary: This article describes the current passenger car problems faced by test system. Advanced test systems on the forefront of science. And look forward to an advanced prospects for the development of test system.Keyword: Advanced t

2、est system；Frontier science; Applications prospectsIn recently, with the callings becoming more and more seriouse, the people pay attention to fatigue life of component which relative to security and economics.So, they all put forward frondose requests for fatigue life of component. In the twenty-fi

3、st century, the fatigue-life forecast of component is applied in companies all over the world step by step. In some circumstance, people can forecast the exact position of fatigue damage and compare the difference fatigue life exists among components under definite load which are made in different m

4、ethod. During the design and modifying of new part, we make fatigue life analysis in order to get the reliable fatigue life of component As result，we can shorten researching cycle and save a lot of experimental outlay. The traditional method is that make experiment with a locomotive sample in test-c

5、ar yard and road, which waste long period and a lot money. However, this method not only cant find out the root of problem, but also do the test after manufacturing the vehicles and that is to say: we can only testit but not forecast. Presently, in the fierce competitions in market, the products ren

6、ovation become increasing and mature products improve continuely to adopt to market requests. Therefore, the importance of fatigue life analysis of component in product design and improvement is regarded by researcher.With high-speed, heavy-duty train the development of railway vehicles Kinetic prop

Usually in the bogie Design, the use of specialized software, the dynamic performance of the bogie Optimization parameters, but because of factors such as man

8、ufacturing processes, these performance parameters The number of actual values vary greatly with the theoretical value, it is difficult to grasp in the design, As a result, often resulting in the manufacture of car design after the performance of less than Seeking, or spend a lot of test time and fu

9、nding need to meet the demand, not Only lead to waste of resources, but also delayed the project. So the rolling stock factory in Chin Bogie Development Bank have called for the bogie when the parameters for testing. West National Chiao Tung University and Zhuzhou Southern factories vehicles, develo

The entire test bed is the key to the hydraulic servo loading system and test Analysis system.At present, the trains of increasing speed on mai

11、n railway lines have worked. The carriage with high speed and carriage with heavy load are the future trend established. Bogie framework is one of the most important carrying components in rolling stock, which is the structure of a non-steering for rolling stock. A great of research both at home and

12、 abroad indicates that failure models of rolling stock. framework are usually fatigue breaking under the function of random load. In order to guarantee the safety of traveling train, it is important to analyze the fatigue life evaluation and reliability design. This paper analyzes the finite stress&

13、strain ofbogie framework and welding seam, and then its fatigue life based on finite element analysis software Hypermesh, MSC.Patran/Nastran and fatigue software, so we deduce reliable prediction of fatigue life and save a great deal of experimentation cost. The thesis has significant guiding meanin
