    STUDY ON VIBRATION FATIGUE CHARACTERISTICS OF SAFETY HANGER FOR METRO VEHICLE by ZHANG FuBing, WU PingBo, QU Sheng

    Published 2018-01-01
    “…Aiming at analyzing the reason of damage of safety hanger on metro vehicle,the finite element model and modal test was conducted for modal analysis.Finally,the natural modes near 340 Hz and 990 Hz were obtained.At the same time,in order to obtain the acceleration and dynamic stress level of the safety hanger in the operation process,a line tracking test was performed on the vehicle.According to the test data,it was found that due to the presence of rail corrugation excitation,the energy of the dynamic stress and acceleration at 340 Hz increased sharply,which indicates that the first-order mode was excited to generate resonance.According to the dynamic stress data before and after the rail corrugation,the fatigue life of the safety hanger was evaluated and compared.It is found that the fatigue damage caused by the rail corrugation greatly shortens the service life of the safety hanger.…”

    Simulation of the Load Sharing for the Four Gears Parallel Drive of Shield Machine Cutter by Wang Lihua, Zhang Chunyou, Wu Xiaoqiang

    Published 2015-01-01
    “…The dynamics equation of the four gears parallel drive system of shield machine cutter is established.The 3D model of the four gears parallel drive system is established by using the UG software.The dynamic process of the four gears parallel drive system is simulated by using the ADAMS software.Then the influence of meshing damping,meshing stiffness,backlash and distribution of driving gear on the load sharing are also analyzed.The research shows that the larger the difference between meshing stiffness and meshing damping is,the more uneven the load sharing is,when the driving load changes,backlash has a larger effect on the load balance,the different distributions of driving gear have rather a great impact on the stability of driven system.The results can provide theoretical basis for the design and manufacture of the four gears parallel drive system.…”

    Efficient three-party authenticated key agreement protocol based on chaotic map by Xiong LI, Fan WU, Jun-guo LIAO, Yu-zhen LIU

    Published 2016-06-01
    “…Chaotic map has been used in the design of key agreement protocol due to its excellent properties.In most of password three-party authenticated key agreement protocol based on chaotic map,the server needs to store a sensitive password table.It makes these protocols vulnerable to some password related attacks.Besides,it would be dangerous if the password table was leaked.To resolve the aforementioned problems,a new password three-party authenticated key agreement protocol based on chaotic maps was proposed.The server didn't need to maintain a password table,so the proposed scheme was free from password related attack.Compared with other related proto-cols,the proposed protocol not only enhances the security,but also improves the efficiency greatly.…”

    Memory contents patch based virtual machine synchronization by Jian-wei LIAO, Shan-xiong CHEN, Li LI

    Published 2012-09-01
    “…A quantitative analysis has been conducted on memory contents difference for various high availability benchmarks.Based on this study memory contents patch based backup virtual machine(VM)synchronization technique was proposed,which finds the best match memory section for each dirty memory section;then compresses the difference contents in these two sections using hash based XOR compression technique in the primary VM; finally,it sends the packed data to the backup VM.For the backup VM part,it first decodes the received data and re-constructs the dirty pages,and then applies these pages to complete the VM synchronization.The experimental results show that compared with regular asynchronous replication,the proposed mechanism can reduce the synchronization data and network traffic by up to 80%,and then benefit to the synchronization to a great extent.…”

    Data sharing scheme supporting secure outsourced computation in wireless body area network by Wei-wei ZHANG, Yu-zhao ZHANG, Chao HUANG, Ru ZHANG, Yi-xian YANG

    Published 2017-04-01
    “…How to effectively protect the security of data sharing in WBAN was a key problem to be solved urgently.The traditional CP-ABE mechanism had a 〝one to many〝 data security communication function which was suitable for access control in WBAN,but it had high computational complexity and did not support attribute revocation.Fully considering of limitations on computation and storage of sensor nodes and dynamic user attribute in WBAN,a CP-ABE scheme was proposed which was provably secure against CPA under the standard model and supported attributes revocation,outsourced encryption and decryption.Compared with the proposed schemes,the computation burden on senor nodes is greatly reduced and the user's attribution can be revoked immediately and fine grained while meeting the demand of its security in the proposed scheme.…”
