“…The crack tip constraint and failure assessment diagram （FAD） in both plate specimen and pipe structure were studied to find out the compatibility and correlation of between the sample and piple.Based on the finite element method, constraints at crack tip of central cracked plate （CCP） specimen and cracked pressure pipe were obtained.It was found that crack tip constraint of CCP specimen under uniaxial loading is better matched with thick-walled pipeline under axial tensile loading, while CCP specimen under biaxial loading is better matched with thin-walled pipeline under internal pressure.In addition, the failure assessment diagram of CCP specimen and pipeline were obtained.It was found that FAD of CCP specimen is less related with thickness, when the thickness of pipe is within the range of thick wall or thin wall; was also pointed out that stress parallel to the crack direction increases the failure assessment curve （FAC） of the structure. …”

STUDY ON VIBRATION CHARACTERISTICS OF ROTOR SYSTEM WITH COUPLING FAULT OF DISC⁃SHAFT LOOSENESS AND RUBBING by TIAN DanYang, LI ZhiNong, ZHOU ShiJian, LI YunLong

“…During the operation of the rotor system,parts may fall and loose,resulting in rubbing between the external object and the rotor shaft.To solve this problem,a finite element model of rotor systems with coupling fault was established by considering the case that disc⁃shaft loosening and rubbing occur simultaneously.Ansys was employed to simulate the rotor system.The influence of the looseness on the vibration characteristics of the rotor system was analyzed.Experiments were carried out to verify the simulation results.The results show that the time⁃domain waveform of the rotor system changes periodically,and the spectrogram mainly contains the first harmonic component.With the aggravation of the looseness,high frequency components gradually appear in the spectrum.The initial value of the speed difference of the disc⁃shaft in the start⁃up phase gradually increases with the aggravation of the loosening.The vibration amplitude of the disc center trajectory in the vertical direction also increases with the aggravation of the looseness,and the orbit shape becomes more complex.Due to the influence of the rubbing,the vibration in the vertical direction is obviously suppressed,and its amplitude is smaller than that in the horizontal direction.The research results have very important reference value for the study on dynamic characteristics of rotor systems with coupling faults.…”

转向节特性对盘式制动器尖叫影响的研究 by 金鑫君, 方晓汾, 邓小雷

“…Considering that the effect of steering knuckle on squeal is usually ignored when performing analysis of disc brake squeal,in this work,a finite element model of disc brake system including steering knuckle component is established,and the vibration characteristics of the brake system are predicted and analyzed by using complex eigenvalue analysis method.On this basis,the influence of steering knuckle characteristics on brake squeal instability behavior is studied.The results show that the increase of friction coefficient will enhance the tendency of braking system to generate squeal instability,and the steering knuckle plays a significant role in affecting the coupling between different components of the brake system.The mode of knuckle may induce the generation of brake squeal.Ignoring the steering knuckle during squeal analysis and prediction will cause the phenomenon of‘over-prediction’and ‘under-prediction’.The stiffness of steering knuckle has a strong influence on squeal behavior.The increase of steering knuckle stiffness will cause more unstable vibration of frequency and accordingly increase the squeal intensity of the system.In addition,since there is no significant friction movement between the knuckle and the disc hub,the friction coefficient at the knuckle-disc hub connection shows little impact on the braking squeal behavior of the system.The above research results provide a basis for understanding the generation of brake squeal and proposing reasonable measures to improve the squeal.…”
