An investigation into the swash plate vibration and pressure pulsation of piston pumps based on full fluid structure interactions
In this paper, dynamic analyses of the swash plate vibration and pressure pulsation of an aircraft piston pump based on fluid structure interactions (FSIs) are presented. Models of the swash plate piston pumps with three FSIs (named full FSIs and non FSI) are given. The simulation results of the discharge pressures at different rotation speeds in the synthesized pump model and experiments show good agreement. The numerical simulation results of the forces on the swash plate and the flow rate of the outlet chamber are presented and compared. The results of the two models show that the discharge pressure pulsation mostly depends on the kinematic relations of the piston slipper shoe units (FSI 1) and is almost isolated from the swash plate vibration. The full FSIs simulation shows that the swash plate vibration is strongly influenced by the pressure pulsation through the control actuator mechanism (FSI 2) and the control valve mechanism (FSI 3) but the non FSI model does not show the same result. The full FSIs model is much more accurate in predicting the vibration of the swash plate and the pulsation of the discharge pressure than the non FSI model.Zhong Wen Gai Yao Mu De Hang Kong Zhu Sai Beng Shi Fei Ji Ye Ya Xi Tong De He Xin Yuan Jian ,Ju You Gao Ya Gao Zhuan Su De Te Dian ,Qi Ya Li Mai Dong Shi Fei Ji Ye Ya Xi Tong Zhen Dong De Zhu Yao Ji Li Yuan ,Dui Fei Ji Ye Ya Xi Tong De An Quan Xing He Ke Kao Xing Ju You Zhong Yao Ying Xiang Ben Wen Shou Ci Quan Mian Fen Xi Liao Ya Li Mai Dong He Xie Pan Zhen Dong Zhi Jian De Guan Xi ,Dui Jiang Di Zhu Sai Beng De Ya Li Mai Dong Ti Gao Qi Ke Kao Xing Ju You Zhong Yao Li Lun Yi Yi Chuang Xin Dian 1.
