[0002] When the continuous rotation electro-hydraulic servo motor is working, the blades inevitably undergo the conversion of high pressure and low pressure. When the motor blades rotate from the high-pressure area to the low-pressure area, it will cause pressure shock to the blades. This pressure shock affects the electro-hydraulic The low-speed performance of the servo motor; in order to reduce the pressure impact of the motor blades when switching between high and low pressure oil chambers and ensure the performance of the motor when it rotates, the main improvement method is to design a buffer groove on the motor oil distribution plate; the shape of the buffer groove is U Type, hole type, semicircle and triangular cone, in addition, there are composite grooves; triangular cone buffer grooves have outstanding effects in reducing hydraulic shock and are widely used. However, with the development of hydraulic technology, simple The designed buffer tank can no longer meet the needs of the market; in this context, the present invention designs a cube-shaped pre-compression cavity structure, and uses the fruit fly algorithm to optimize the side length of the pre-compression cavity structure

The invention relates to a fruit fly algorithm-based pre-compression cavity structure design method. The method mainly comprises the following steps of 1, establishing a continuous rotation electro-hydraulic servo motor pre-compression cavity model; and 2, establishing a fluid model and dividing a grid; 3, carrying out simulation analysis on the pressure reduction process of the pre-compression accommodating cavity by using FULENT software; and 4, based on a simulation result, obtaining the interval of the optimal size of the pre-compression accommodating cavity; and 5, determining a taste concentration determination function S (i), and optimizing the structure of the pre-compression cavity by applying a fruit fly optimization algorithm. By means of the method, the cube type pre-compression containing cavity structure with the optimal structure is obtained, and therefore the pressure impact of the continuous rotation electro-hydraulic servo motor is effectively relieved.
