Stiffness Model of Rolling Bearing Considering Clearance and Analysis of Its Time-varying Characteristic by Runlin Chen, Qin Han, Menghao Zhang, Yanchao Zhang, Longlong Li, Yahui Cui

“…The results show that the average stiffness of the bearing is negatively related to the radial clearance and positively related to the load and the number of rolling elements； the stiffness amplitude change rate generally increases with the increase of the radial clearance， and decreases with the increase of the load and the number of rolling elements. …”

Hybrid precoding method for millimeter-wave massive MIMO systems based on IAFS algorithm by Haoyi CHEN, Guangqiu LI, Hui LI

“…The millimeter-wave massive multiple-input multiple-output (MIMO) systems can overcome the adverse effects of the free-space signal path loss through the partial connection hybrid precoding method, which has the advantages of low hardware complexity and high energy efficiency.When the number of input data streams is equal to the number of radio frequency (RF) links, the hybrid precoding method based on partially connected structure and serial interference cancellation can be used.When the number of input data streams is not equal to the number of RF links, a hybrid precoding method based on improved artificial fish swarm (IAFS) algorithm was proposed.The core idea is that based on the spectral efficiency optimization criteria and the characteristics of partial connected structure, the spectral efficiency optimization problem of analog recoding matrix variables was transformed into the spectral efficiency optimization problem based on vector variables, and then the IAFS algorithm was used to solve the spectrum efficiency optimization problem.The simulation results show that the proposed method has good spectral efficiency and energy efficiency under the condition of low signal-to-noise ratio, and is expected to be applied in the real scene.…”

Multi-source data security protection of smart grid based on combination key by Jian GAO, Wenbin CHEN, Jianmin PANG, Huadong YU, Guorui SONG

“…As an important infrastructure of power system,power communication network has deployed a large number of widely distributed business terminals and communication terminals,whose data security is related to the safe and stable operation of the entire power network.In order to avoid the situation that the information cannot be safely exchanged due to the shortage of keys.The sharding and combination technology based on keys was proposed to realize the expansion of limited keys,so as to solve the problem of a large number of keys needed for multi-node and mul-ti-service.Firstly,a sharding scheme was obtained according to different conditions.A key was divided into several dif-ferent sub-key pieces,and then a new key was generated by combining these key pieces and distributed to different ter-minals in the system.A large number of combined keys generated were conducive to update key ,which could ensure the data service “one at a time” and effectively enhance the communication system's ability to resist damage and invasion.Through analysis and calculation,the effectiveness of this method in realizing real-time update of a large number of ter-minal business keys with limited keys was further verified,and data secure communication was realized.…”
