Research And Study On The Development Of Fatigue Testing Technology And Software Of HCQ-3.0 Testing System

The dissertation mainly introduces the research and development work of the HCQ-3.0 Testing System for Automobile's Rear-Axle. Some research work is done on fatigue testing based on the theory of fatigue experiments and analysis of results. Also the dissertation analyzed how the system is designed from the aspects of hardware and software, introduced the realization of the testing system and various module of it.The dissertation is divided into seven parts, and the main content of every part is presented as follow:In chapter one, the background of the dissertation and of HCQ-3.0 testing system is discussed, along with the purpose of auto testing and the testing method of it. It also discussed the development of auto testing technology and the application of new technology in auto testing. At last it mentioned my assignment and the functions of HCQ-3. 0 testing system.In chapter two, it introduced the basic structure and different forms of fatigue failure of retarder. Then it used EHL theory to analyze fatigue failure. At last technology of fatigue testing, statistics process and software programming are presented.In chapter three, fist it listed the parameters we need to measure then introduced how to program the software for them. Also it discussed the control system and mechanical system. At last it introduces us the structure of these systems and the software.In chapter four, the basic theory of computer control system and the design of software for them are discussed. Also How add load to the system automatically is presented, the load system is discussed particularly because of it's importance for the whole system.In chapter five the author showed us how to program with the system and how the core technology of the software is designed, the core technology are D1K database and data processing and so on. At last some examples of testing modules are presented, we will see some interfaces and some flow charts.In chapter six, It introduces how to use the minimum Rear-Axles to get the result of most Axles and the simulated braking system testing is presented. Also the author shows us some interfaces of the software, and some simulated data is listed.In chapter seven, the work of the dissertation is summarized and the further research work is looked ahead.
