Authors: Zhu Caizhi , Wu Ji , Liu Jun , Zheng Jiaqi 
Published: December 2019

Abstract
The harmonic reducer has been widely used in military, industrial and agricultural fields because of its large transmission ratio, high precision, small backlash, stable transmission and small volume and weight. Flexible bearing is a key component of harmonic reducer, and its static mechanical properties are one of the main factors influencing the fatigue life and load carrying capacity of harmonic reducer. Mathematical model of contact force between rolling element and outer ring is established basing on three bending moment equations. This paper takes the CSF-40-80 flexible bearing with double eccentric arc cam as the research object, the finite element methods (FEM) analysis is used to study the deformation and stress of the flexible bearing under no-load and load. The effect of the double eccentric arc cam eccentricity on the stress is also presented, which provides theoretical support for the optimization of harmonic reducers and the manufacture of high-performance harmonic drive systems.

Published: December 2019

Abstract
This paper is mainly about the impact of electrostatic forces on the collision efficiency, whinch collision is caused by the internal forces between micro-particles. The Fourth-order Runge-Kutta method is used to solve the dynamical equations of the micro-particle collision. Studies have shown that the micro-particles with the same charge have the same initial velocity, the larger the volume of the particles, the more the charge amount, and the different particle size has a greater impact on the repulsion effect during the collision. That is, the repulsion effect exhibited in the collision between particles is related to the particle size; Micro-particles with different kinds of charges have the same initial velocity, the smaller the volume, the less the charge amount, and the smaller the particle size, the more attractive the collision effect during the collision.

Effect of Multichannel Signal Sequence on Source Localization Using Convolutional Neural Network
Authors: Zhang Yinquan , Zhang Shuang , Wu Kaiming , Gao Siyu , Li Dong , Liu Jie , Li Guofu 
Published: December 2019

Abstract
In recent years, machine learning has become a promising data-driven method of source localization in underwater acoustics. Several algorithms have been developed by taking advantage of neural networks. This paper investigates the effect of multichannel signal sequence on the performance of source localization using a convolutional neutral network (CNN). In this paper, source localization is solved as a classification problem. The performances of different sequences are demonstrated to be quite different. For a specific CNN, it is revealed that the multichannel sequence affects source localization through influencing the complexity of range classification. The complexity can be reasonably reflected by the conspicuousness of signal differences between adjacent range categories. The two-dimensional (2D) Fourier spectrum of the signal differences provides an intuitive approach to describe the conspicuousness. The multichannel sequence that could induce greater spectral amplitudes has better localization performance in noisy environments.

Numerical Simulation Calculation and Analysis of the Effect of Rocket and Duck Rudder on Its Aerodynamic Characteristics and Flexible Deformation
Authors: Chen Han , Chen Dongyang 
Published: December 2019

Abstract
Based on inertia relief and CFD/CSD two-way coupling methods, the static aeroelasticity numerical simulation of a simply guided rocket with duck rudder actuator has been done, and the influence of duck rudder on aerodynamic characteristics and flexible deformation has been analyzed. Firstly, the lift, drag force and pitch moment coefficients, etc. had been calculated by using CFD method based on SST k-ω turbulence model, the error was less than 10 percent compared with the experimential data, and it verified the accuracy of fluid domain numerical method. Then, the two-way fluid-structure interaction simulation on the rocket and the contrastive analysis were done based on ANSYS Workbench multi-physics coupling simulation platform. The results show that duck rudder has a larger influence on rocket aerodynamic characteristics, by analysing the rocket aerodynamic coefficients under the conditions of without duck rudder, 0° rudder angle and 10° rudder angle, and it shows that the lift force and pitch moment coefficients change 5 to 30 percent with or without duck rudder and angle. Considering the influence of flexible deformation on aerodynamic coefficients, the flexible deformation has a more influence on the lift force and pitch moment coefficients, it reflects that the flexible deformation leads to the lift force coefficients smaller and pitch moment coefficients absolute value smaller, the maximum influence can reach to 5 to 10 percent. Meanwhile, the results show that the maximum deformation of rocket occurred in the middle of the rocket body, and the maximum equivalent stress occurred in the empennage of the rocket. Therefore, in the design of simply guided rockets, it’s very important to consider the influence of duck rudder on the aerodynamic characteristics and flexible deformation.

Authors: Yang Xiaotong 
Published: December 2019

AbstractBased on the integrated perspectives of social learning theory and affect event theory, the paper discusses the impact mechanism of responsible leadership on employee green behavior. Questionnaire survey on 317 employees from many enterprises in Shandong Province and Shanghai in this paper, it is found that responsible leadership has a positive effect on employee green behavior, and moral reflectiveness plays a complete mediating role between responsible leadership and employee green behavior. Empathy moderates the negative relationship between moral reflectiveness and employee green behavior such that moral reflectiveness has a weaker negative effect on employee green behavior when employees’empathy is higher. Furthermore, empathy moderates the mediating effect of moral reflectiveness between responsible leadership and employee green behavior, the mediating effect of moral reflectiveness is weaker when empathy is higher. The results of this paper provide a new perspective for understanding how responsible leadership stimulates employee green behaviors, and have important practical significance for strengthening the environmental protection behaviors of organizations.
