Recent Developments on Hybrid Time-Frequency Numerical Simulation Techniques for RF and Microwave Applications by Jorge F. Oliveira, José C. Pedro

“…This paper reviews some of the promising doors that functional analysis techniques have recently opened in the field of electronic circuit simulation. Because of the modulated nature of radio frequency (RF) signals, the corresponding electronic circuits seem to operate in a slow time scale for the aperiodic information and another, much faster, time scale for the periodic carrier. …”

The Tensile Strength of Loess in Northwest China by Unconfined Penetration Test and the Distinct Element Simulation by Xuyang Wu, Yun Bao, Mingyang Ren, Qingguo Liang

“…The experiment and numerical simulation results show the following: (1) the split angle (α) presents an exponential decrease with tensile strength (σt) and a linear decrease with internal friction angle (φ); (2) K that can be written as tan (2α + φ) is a coefficient to calculate tensile strength, which is equal to 2.00 for remolded loess and 1.50 for undisturbed loess; (3) the distinct element simulation shows that the resisting force by the UP test comes from both tensile stress and shear stress; (4) the tensile fractures and shear fractures appear at almost the same time when the tensile stress is approximately 70% of tensile strength.…”

Thermo-mechanical Coupling Simulation Analysis of Cycloid Gear Multi-tooth Form Grinding by Shi Enbing, Su Jianxin, Zhang Lifang, Deng Xiaozhong, Ren Xiaozhong, Cheng Chen

“…The cycloid gear multi-tooth form grinding is a gear finishing process，which can finish the processing of three tooth grooves at same time.In the process of high-speed grinding，high temperature will arise on the gear surface instantaneously，which may cause tooth surface burn.The temperature gradient formed by grinding temperature field will cause residual stress on the tooth surface，and the metallographic structure of cycloid gear tooth surface will change，affecting the grinding accuracy of the gear.The finite element method is used to simulate the temperature field of cycloid gear multi-tooth form grinding，and then the thermo-mechanical coupling analysis method is used to obtain the numerical simulation nephogram of the temperature field and thermal stress of cycloid gear form grinding.Through the analysis of the main stress of the grinding area，it can be seen that the stress is mainly concentrated at the grinding center near the root of the tooth，and the grinding area presents hot-pressing stress.In the ground area，the hot-pressing stress is converted into thermal tensile stress and gradually forms residual tensile stress，and the node stress also changes correspondingly with the change of grinding process parameters.The conclusion has certain research significance for predicting the distribution of temperature and thermal stress field during multi-tooth form grinding and reasonably selecting grinding process parameters.…”
