    Hybrid Vibration Control under Broadband Excitation and Variable Temperature Using Viscoelastic Neutralizer and Adaptive Feedforward Approach by João C. O. Marra, Eduardo M. O. Lopes, José João de Espíndola, Walter Antônio Gontijo

    Published 2016-01-01
    “…In that context, this work deals with the development and practical implementation of a hybrid (passive-active/adaptive) vibration control system over a metallic beam excited by a broadband signal and under variable temperature, between 5 and 35°C. Since temperature variations affect directly and considerably the performance of the passive control system, composed of a viscoelastic dynamic vibration neutralizer (also called a viscoelastic dynamic vibration absorber), the associative strategy of using an active-adaptive vibration control system (based on a feedforward approach with the use of the FXLMS algorithm) working together with the passive one has shown to be a good option to compensate the neutralizer loss of performance and generally maintain the extended overall level of vibration control. …”

    RESEARCH ON LOW AND HIGH CYCLE FATIGUE BEHAVIOR OF NI-CR ALLOY UNDER DIFFERENT FREQUENCY AT ROOM TEMPERATURE by WU HaiLi, AN ChunXiang, YU Xiao, LU LianTao

    Published 2018-01-01
    “…Low cycle fatigue test(0.1 Hz <sup> </sup>0.3 Hz,10~3<sup> </sup>10~5 cycles) and conventional high cycle fatigue test(150 Hz.10~4<sup> </sup>10~7 cycles) and ultra-high cycle fatigue test(20 k Hz,10~5<sup> </sup>10~9 cycles) were carried on Ni-Cr Alloy at room temperature.The results of the three forms fatigue test were compared,and the energy-life curve reduced by 3-parameters power function were fitted.The fractograph of specimens were investigated and analyzed with scanning electron microscope.The results show that the fatigue crack initiation sites change from multiple surface cracks to single surface crack,then to subsurface of specimen with decreasing the load amplitude.…”
