Research & Develope The Control System For Underwater Vibration Experiment Environment

In this dissertation, the control system for underwater vibration experiment environment has been studied.In chapter 1 ,the aims of the dissertation are presented. A survey of important role and main characters of acoustic transducer is introduced at first. Then the situation of the methods of vibration experiment and vibration table is put forward relate with the purpose of project. At last, the main task of this dissertation is addressed.In chapter 2, the design methods of experiment environment are presented. The constitution and principle of each vibration experiment is discussed respectively in term with the function of the system at first. Then design an experiment environment of the whole system and introduce the technology of serial communication. At last, technical parameter of system is given.In chapter 3, the transfer function of the underwater vibration table is researched. First the vibration table model in air environment is established. Then the fluid-solid coupling theory is addressed and the difference of dynamic property between in air and water is pointed out. At last the simulation experiment is carried out to validate the difference.In chapter 4,the control method of system is presented. A strategy to control the level of vibration is designed at first. Then the interrelations between parameters, the methods of control and the course of each experiment are elaborated in detail.In chapter 5, the control software of vibration system is discussed. First, programming platform, programming tools and programming language are discussed. Then, the whole program is introduced and the arithmetic and flow are given.In chapter 6, the result of experiment is summarized and the performance of the system is analyzed.In chapter 7, summarize the system, put forward the further research work which will be done in the near further.
