title = "Numerical Analysis of Seal Force Under Brush Seal Hysteresis Effect",
abstract = "Brush seal has certain advantages over traditional labyrinth seal. As the hysteresis characteristics of the brush seal is a key factor affecting its sealing performance, it is particularly important to conduct in-depth study on the seal force. This paper takes hysteresis as the premise of research, and establishes the model of brush seal force with whole circle bristles under the hysteresis considering the 3D bending of bristles, and set up the dynamic equation of brush seal force for whole circle bristles. This work further studies the influence of system parameters on the brush seal force under the hysteresis, and compares the influence of each system parameter on seal force. And then compared with the model without hysteresis to study the influence degree of hysteresis effect on seal force. The results show that the hysteresis has a great influence on the variation trend of brush seal force, and the seal force is much smaller when the hysteresis effect is taken into account than that not considered. The increase of bristle inclination is beneficial to increase the stability of the rotor system, but for the seal force on the rotor, the greater lay angle is not better. It is of great significance to study the seal force under the lag of brush seal to further understand the sealing characteristics of brush seal.",
