ABSTRACT
High-pressure oil pipes are widely used in all kinds of machinery and engineering, but the intermittent nature of fuel entering and ejecting the oil pipe makes it difficult to control the pressure in the pipe. This paper mainly studies how to design the scheduling strategy of the oil pipe pump according to the mathematical physical equations of the change of fuel pressure in the high-pressure oil pipe. In this paper, an efficient search algorithm is proposed, and the method of estimating the optimal value is used to avoid the algorithm from falling into the local optimal. We find in order to stabilize the pressure in the pipe at 100MPa, the optimal opening time of the one-way valve in one cycle is 0.2859ms. Benefit the basic model, we give a solution to increase form 100MPa within 2s and stabilize at 150MPa: before 2s, the opening time of the one-way valve is 1.1089ms; after 2s, the opening time is adjusted to 0.7526ms.
