Research on buffer structure and flow field simulation of swash plate plunger type hydraulic transformer
文献摘要：
In order to solve the problem of excessive noise and vibration during the operation of the hy- draulic transformer, an optimization method of valve plate damping hole structure is proposed to alle- viate the phenomenon of pressure shock. Firstly, the mathematical model of oil pressure gradient in the plunger cavity is established, and the incremental equation of pressure change is derived. Sec- ondly, a kind of buffering structure is proposed, the corresponding relationship between the pressure change and the envelopment angle of the buffering hole and the aperture size is determined by analy- zing the oil pressure change curve in the plunger cavity. Finally, the flow field models with buffering holes are established, and the transient simulation of the pressure change process under the optimal solution is carried out with ANSYS software and the flow field pressure distribution contours are ob- tained. Through the analysis of simulation results, it is concluded that the optimal envelope angle of the three buffer holes of A-T-B-A is 5 °, and the optimal aperture is 1. 8 mm, 1. 6 mm, and 1. 7 mm, respectively. The buffer hole can achieve a better-buffering effect in the range of variable pressure an- gle[0 °,101 °] . The buffer hole structure can effectively alleviate the pressure shock and reduce the noise level, which lays a foundation for the design and theoretical research of hydraulic transformers.
