The Research Of A New Kind Of Pressure Feedback Nitrogen Inflating Mechatronical Hydraulic Impactor System

Based on the analysis of the defect of hydraulic impactor at home and abroad, this dissertation breakthrough the tradition frame of impactor, led to an innovative pressure feedback nitrogen inflating mechtronical hydraulic impactor. The innovation, which in principles stmcture~ cortrol ways test means, make it become a flexicible impactor which with a lot of flexicible attributes, such as time flexility.. space flexility.. object flexility. surroundings flexility.. interchange flexility~ software flexility etc. According to the physical characteristics of impacted object, the new impactor could adjust the impact energy and frequency automatically and steplessly, and realized intelligence breaking. After establishing the nonlinear mathematical model of the impactor, a object-oriented simulation model of new impactor has been construct, and the regularity about the new impactor motion has been found out. Breaking through the tradition test way, a new test way, called air pressure way, is brought forward first, which is used determine the piston抯 velocity and frequence, and questions within tradition test way ware solved. The new test way can be used testing impactor on line. The proposition that identifies the characeristic of work object according to the anti-rebound velocity of piston, which be convert by rate of air pressure in nitrogen room, was put forward for the first time. Illation and experiment have confirmed its feasibility. The author designed a single chip microcontroller system of hydraulic impactor. The fuzzy control method was applied on the hydraulic impactor, and realized the fuzzy control to the output parameters of hydraulic impactor. Based on the theoretics of new impactor, a prototype, DBS-SOO, has been made. According to the data collected from the experiment, the simulation results were in good agreement experimental ones. So the expected purpose of the prototype experiment was achieved. With all the achievements mentioned above, the design and research theoretical system of flexicible impactor, based on the pressure feedback nitrogen inflating mechtronical hydraulic impactor, is established. The offering of concept of flexicible impact and the reseach of flexicible impactor would be made important influence to the reseach of impact theoy and the development of impactor industry. Besides, the design theoretics of new impactor and new test way are valuble to impactor抯 designs producation monitor.. maintain.
