Abstract

The invention relates to a pulse digital flow double-generator peak shifting and superposition output method. According to the pulse digital flow double-generator peak shifting and superposition output method, two pulse digital flow generators are configured; according to the phase positions output by the two pulse digital flow generators, when one pulse digital flow generator is located in the reversing position, the other pulse digital flow generator is located in an oil pressing stroke, fluid pulse outputs and electric pulse coded signals of the two pulse digital flow generators are superposed respectively through a peak shifting method to a train of fluid pulses, namely, the total pulse digital flow output through peak shifting; the instantaneous no-pressure flow output conditions existing between all the fluid pulses are eliminated when the single generation is applied, that is, the generated pulse digital flow has the continuous pressure and flow output properties. Thus, a work object operates more smoothly and continuously. Occurrence of the adverse phenomena such as impact, creep and vibration under high-pressure and heavy-load working conditions can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of fluid transmission and control in the discipline of mechanical engineering, in particular to a pulse digital stream method for realizing digital control of a fluid system by adopting dual generators for staggered peak superposition output. Background technique [0002] Fluid transmission and control is an engineering technology widely used in many fields of national economy. It can not only realize high-power transmission, but also an important means of control. As the requirements of digital technology in the information age become more and more common and higher, the use of computers to carry out real-time digital control of fluid components and fluid power systems has become an important trend in the development of fluid technology. Over the years, people have done a lot of work on this, and many methods have been proposed and applied so far, and the pulse digital stream technology is one of them. [...
