The Research Of A Full Hydraulic Pressure Hydraulic Impactor With Strike Energy And Strike Frequency Adjusted Steplessly

On account of the hydraulic impact machine being applied rapidly in many fields, it brings forward their higher technique capability for different working conditions. It is well known that the output working parameters of the hydraulic impact machine is strike energy(E) and strike frequency(f)and rational matching of its working parameters can adapt different working conditions, bring optimal working effect. Accordingly enhance productivity decrease cost and enlarge its use field.At the present time, the working organ of home and abroad hydraulic impact machine the hydraulic impactor all is distance feedback control mode. The distance feedback working principles of the hydraulic impactor determines its technical properties, so the working parameters of the hydraulic impactor cannot be adjusted independently and steplessly. In this dissertation, with the analysis of the hydraulic impaetor at home and abroad, it break up the traditional travel feedback control principles, introduces pressure feedback principles, leads to an innovation full hydraulic pressure hydraulic impactor with strike energy & strike frequency adjusted steplessly and hydraulic control system. Its design theories and methods were methods researched. As a result of many innovations on working principles, mechanism, control method and design theory, the new hydraulic impactor has especial working properties. Workman can adjust automatically the impact energy and frequency to the physical characteristics of working medium by manipulating a handle in long-distance, so achieve optimal matching of its working parameters. In order to adapt the pressure feedback principles, it designs a new forerunner control valve, basing on the study of its static design and computer dynamic digital simulation, open out its parameters affect the hydraulic impactor property and offers theory for more perfect design. After establishing the nonlinear mathematical mode of the new hydraulic impaetor. a dynamical simulation of the new hydraulic impactor has been conducted, and regularity about the mechanism motion has been found out. The dissertation conducts a theory and experiment study on circumfluence fount of the hydraulic impactor. establishes theory foundation for the popularity and application of the back-controlIIhydraulic impactor. It apply self-adaptive cybernetics to a buffer of the hydraulic impactor. bring forward a control system of the self-adaptive buffer of the hydraulic impactor which is controlled by single梒hip computer and walking electromotor, after a computer dynamic digital simulation, it demonstrates the feasibility of the new buffer. After overcoming shortage of those traditional hydraulic impactores, the new experiment prototype of the full hydraulic pressure hydraulic impactor with strike energy and frequency adjusted steplessly has been made. According to the experiment. the simulation results were in good agreement experiment ones. So the expected purpose of the prototype experiment was achieved, the correctness of the theory study was proved.The dissertation challenges tradition, develops the full hydraulic pressure hydraulic impactor with strike energy and frequency adjusted steplessly and independently, and proves its superior technical properties from theory and practice. It is a new development of the hydraulic impactor and has wide application foreground.
