[Abstract]:In this paper, the reliability modeling and analysis technology of the main amplification system, which is the core of the laser driver, is studied under the background of the national basic technology project "Reliability Engineering Research and Verification of the Giant Laser driver". The basic principles and methods of the basic reliability modeling and task reliability modeling of the main amplification system and the general thinking of component reliability modeling and analysis are given. Taking the pulsed xenon lamp as an example, this paper explores the reliability modeling and analysis technology of the components of the main amplification system under the condition of no component data, and finally refers to many kinds of theoretical methods. The main method of reliability growth analysis of the main amplification system is demonstrated by combining the experimental data of a single beam group of a laser driver. The main contents of this paper are as follows: (1) introduction. This paper expounds the research background and significance of this paper, analyzes the research status of reliability modeling and analysis of the main amplification system at home and abroad, and gives the problems and solutions needed to be studied. The logical relation of each chapter of the thesis is shown. (2) the reliability modeling and analysis of the main amplification system. This paper introduces the basic structure and working principle of the main amplification system. With the aid of the reliability block diagram and mathematical formula, the basic methods and ideas of establishing the basic reliability model and the task reliability model of the main amplification system are given. At the same time, the classical reliability modeling and analysis technology of main amplifier components is discussed systematically. (3) Reliability modeling and analysis of pulse xenon lamp. The failure physics analysis of pulsed xenon lamp is carried out, and the requirement of collecting test data of pulse xenon lamp is put forward. The reliability evaluation model of pulse xenon lamp is established on the basis of failure physics analysis. Finally, based on the experimental data of a pulsed xenon lamp, the reliability modeling and analysis are carried out and the applicability of the model is verified. (4) the reliability growth analysis of the main amplification system. Referring to many kinds of reliability growth analysis theories, the methods suitable for the reliability growth analysis of the main amplification system are abstracted. Based on the experimental data of a single beam group main amplification system of a laser driver, an example of reliability growth analysis of the main amplifier system is given. (5) conclusion. This paper summarizes the work done and points out the problems that need further study and exploration.
