DYNAMIC ANALYSIS AND OPTIMIZATION OF IMPACT MECHANISM FOR IMPACTING AND BREAKING ROCK ROADEADER by LI XiaoHuo, QIAN YaSen, JIAO Li, LI Yan, SHI ShangWei, WENG ZhengYang

“…In order to improve the impact mechanism of the impacting and breaking rock roadheader dynamic characteristics under the cycle impact load,the first six natural frequency and mode shape as well as the displacement-frequency curves were obtained by using stress wave synthesis theory and finite element method in the paper,the modal and harmonic response of the mechanism were analyzed,the main deformation portion and main vibration direction and three axial weakest points of the mechanism were confirmed,structure size optimization of the rocker arm were adopted with multiple objective genetic algorithm,The maximum displacement response of the mechanism was reduced,and the dynamic characteristics of the mechanism were improved,which provides a method and basis for researching and improving the dynamic performance of the mechanism.…”

Influence of Engagement Algorithm and Structure Parameter on Harmonic Drive by Luo Ji, Sha Chun

“…In order to analyze the influence of the engagement algorithm and structure parameter on the transmission performance of harmonic drive（ HD）,the involute tooth profile is used for the HD,an exact engagement algorithm and its approximation are obtained based on the envelope theory and the exact calculations for the rotation angles of flexspline（ FS）,moreover,the conjugate existent domain（ CED） and the conjugate tooth profile（ CTP） that based on the aforementioned algorithm are studied,furthermore,the influence of the wave generator（ WG） and the coefficient of radial displacement are researched here. The results demonstrate that two CEDs and double conjugated phenomenon are found,and the approximate algorithm,the coefficient of radial displacement,the WG have little effect on the CED,CTP,engagement deviation for the CED one,but obviously influence on the CED,CTP,engagement deviation for the CED two.…”

A compressive data gathering method based on El Gamal cryptography by Xiaohan YU, Keming DONG, Xia LI, Chao CHEN

“…As a hot researching area,compressive sensing has advantages in signal process,image processing and data gathering and analysis.How to effectively and safely apply compressive sensing technology to collect data in wireless sensor networks is studied.Conventional compressive sensing technology based data collection method does not consider the security issue.Furthermore,every nod in the network must participate in the process of collecting measurements.The El Gamal cryptography and sparse matrices based compressive sensing technology were combined,and the El Gamal based sparse compressive data gathering (ESCDG) method was proposed.Theoretical analysis and numerical experiments show that ESCDG not only decreases the network resource consumption but also be able to defense the internal and external attacks.…”

Multi-objective task offloading algorithm for mobile cloud computing by Fuhong SONG, Huanlai XING, Wei PAN

“…Mobile devices with limited computing power and resources can offload intensive tasks to the cloud for execution,thus improving the computing capacity of mobile devices and reducing battery energy consumption.However,the existing researches cannot properly balance the application finish time and energy consumption of the mobile terminal when offloading tasks.An MOEA/D based algorithm was proposed to optimize the application finish time and energy consumption,and dynamic voltage frequency scaling technology was introduced into the MOEA/D to adjust the CPU clock frequency of mobile devices to further decrease the energy consumption without increasing the application finish time.The simulation results demonstrate that the proposed algorithm outperforms a number of existing algorithm in terms of the multi-objective performance.…”
