LOCAL RESONANCE ANALYSIS OF CANTILEVER GEAR BOX UNDER GEAR TRANSMISSION EXCITATION by WANG Jue, ZHOU Hang, CHEN DongSheng, ZHANG Rui

“…Local resonance is a key reason for fatigue damage of gear housings.Local modals could be excited by vibration caused by gear meshing.Considering the shearer rocker arm for example,the local resonance characteristics of gear housing are analyzed in this paper.Finite element method is used to obtain the natural characteristics of housing and field testing with 0 load is employed to get the vibration acceleration values at the ratings.Local resonance characteristics are obtained by comparing frequency spectrum and natural frequencies.Housing wall thicknesses are selected as design variables to get the influence to natural frequencies.The results show that new frequencies which consist of meshing frequencies of different transmission stages occur and some of them can cause local resonance.Housing wall thicknesses should be changed to avoid local resonance.Excessive strain stress could be caused by local resonance and incur fatigue damage.This research could be a reference for resonance analysis and optimum design.…”

High-performance federated continual learning algorithm for heterogeneous streaming data by Hui JIANG, Tianliu HE, Min LIU, Sheng SUN, Yuwei WANG

“…Aiming at the problems of poor model performance and low training efficiency in training streaming data of AI models that provide intelligent services, a high-performance federated continual learning algorithm for heterogeneous streaming data (FCL-HSD) was proposed in the distributed terminal system with privacy data.In order to solve the problem of the current model forgetting old data, a model with dynamically extensible structure was introduced in the local training stage, and an extension audit mechanism was designed to ensure the capability of the AI model to recognize old data at the cost of small storage overhead.Considering the heterogeneity of terminal data, a customized global model strategy based on data distribution similarity was designed at the central server side, and an aggregation-by-block manner was implemented for different modules of the model.The feasibility and effectiveness of the proposed algorithm were verified under various data increment scenarios with different data sets.Experimental results show that, compared with existing works, the proposed algorithm can effectively improve the model performance to classify old data on the premise of ensuring the capability to classify new data.…”

Social-aware caching and forwarding for video streaming in information-centric 5G VANET by Tengfei CAO, Cuili JIANG, Zhiqiang LIU, Xiaoying WANG

“…The arrival of 5G-enabled communication technology has laid the foundation for providing high-quality video stream services in vehicular Ad Hoc network (VANET).However,current VANET still distribute video content over IP networks which design for host communication instead of content distribution.The mismatch between network function and design goals brings huge challenges for providing high quality video service.Based on the above questions,a social-aware caching and forwarding was proposed to support efficient video streaming services and the time complexity of the algorithm was O(m²).Firstly,a virtual community was constructed by analyzing the user's behaviors.Then,a fast forwarding scheme was introduced to ensure that users could discover the requested videos nearby.Finally,a community-based caching policy was proposed to optimize the in-community caching distributions.Simulation results show how the proposed strategy achieves better performance than other state-of-art solutions in terms of caching hit ratio,searching delay and control overhead.…”
