Numerical analysis model for the instantaneous grinding temperature of face gears with a worm grinding wheel by WANG Chao, GUO Hui, RUAN Yuhang, RAN Xiaoping, ZHAO Ning

“…ObjectiveThe thermal distribution during the grinding of face gears using a worm grinding wheel is complex, with the heat being concentrated primarily on the surface layer of the wheel teeth, which can lead to thermal deformation and damage. In order to improve the situation, a numerical computational model for the instantaneous grinding temperature of face gears with a worm grinding wheel was established to investigate the distribution and variation patterns of the grinding temperature.MethodsFirstly, based on the geometric contact characteristics between the face gear and the worm grinding wheel during the grinding process, a quadratic surface was employed to approximate the instantaneous contact region and derive a calculation formula for the instantaneous grinding contact area. …”

A Polarity Reversion Elimination Method for LTE-Advanced Frequency Offset Estimation by Guoqing Jia, Shanji Chen, Chao Chen, Xiaohong Ji, Weidong Fang

“…Traditional fractional frequency offset（FFO）estimation algorithm pay less attention to FFO polarity estimation.Noise and channel fading induced FFO estimation polarity reversion degrades the frequency synchronization performance inevitably.An efficient FFO polarity detection method was proposed in LTE-Advanced system to solve the problem，which utilized the mirror symmetry property of time-domain primary synchronization signal（PSS）.Numerical results show that the proposed method can depress FFO polarity reversion efficiently.…”
