    Noise Analysis of Bus Transmission Shaft and Improvement of Vibration Performance by Zhu Zhao, Huang Jun, Zhang Haiyuan, Jiang Hui

    Published 2017-01-01
    “…Aiming at a medium bus driving speed at 60 to 80 km/h,it is found that the problem of vehicle overall noise level is too large and greater vibration of the floor. By using the analysis of noise figure and the vibration waterfall map data,the transmission shaft intermediate support bracket course resonance is confirmed.According to the theory of vibration isolation and finite element analysis,by reducing the stiffness of the intermediate support rubber and increasing the natural frequency of the intermediate support bracket,the vehicle resonance phenomenon is greatly reduced and the vehicle noise is reduced by 4 dB(A). …”

    AUTOMOBILE CRASH BOX IMPROVEMENT AND FORMING ANALYSIS FOR TUBE HYDROFORMING by XU MingTao, WANG LiJuan, CHEN ZongYu, CHENG JiangHong

    Published 2017-01-01
    “…The automobile crash box is an important buffering and absorbing energy structure.Due to the advantages of light weight,high stiffness,high strength and good crashworthiness for hydroforming tubular,the hydroforming crash box is designed instead of the stamping and welding structure.By numerical simulation,analysis the crash box key energy absorption properties,comparison of tube hydroforming crash box and stamping one absorbing performance.Design the load-curves for Tube Hydroforming automobile crash box,which is influence the crash box thickness distribution after forming.In this paper,maximizing of the minimum wall thickness of crash box after hydroforming is used as the research object,select the pressure control parameter on the load-curves as design variables,using fractional factorial designed experiment,then use of Kriging spatial interpolation method to build approximation model,Finally,the use of genetic algorithm to obtain the optimized loadcurves,increasing the minimum wall thickness of crash box after hydroforming.…”
