    Research on Deformation Characteristics of Geomembrane in Welding of Membrane Faced Rockfill Dam by WU Xiuyu, ZHANG Xianlei, WU Yunyun

    Published 2021-01-01
    “…In order to solve the problem that the roughness and local folds of geomembrane in the meridional and zonal welds affect the welding quality,this paper carries out the experimental study on thermodynamic deformation-temperature rule of HDPE/PE/PVC geomembrane by thermal mechanical analyzer,and reveals the deformation characteristics of geomembrane in welding construction by combining the experimental study with theoretical analysis.The experimental results show that the main cause is the difference between the meridional/zonal deformation,and the essential reasons are the history of temperature stress and the orientation of molecular structure of geomembrane in the production process.After being fully fused and formed by natural cooling under unconstrained conditions,the sample is subjected to deformation-temperature test.The test results verify the rationality of the theoretical analysis.According to the results,this paper proposes to improve the production process by avoiding the orientation of molecular structure,reasonably controlling the cooling temperature rate gradient and appropriately increasing the lap width between the meridional and zonal welds to offset the different deformation caused by the remakable differenence of thermodynamic deformation characteristics.…”

    风机偏心对空冷梁式桥架振动实验研究 by 郭铁能, 孟令军, 白春生, 华旭

    Published 2021-01-01
    “…The vibration problem of air-cooling fan bridge has been troubling the north thermal power plant.Excessive vibration amplitude causes the damage of fan,motor,reducer and other equipment,and affects the stability and economic benefit of power plant operation.In this paper,the vibration speed of the air-cooling fan exceeded the standard as the research object,and the data acquisition instrument and acceleration sensor were used to test the vibration of the air cooling fan bridge in the power plant of xiaoyi in Shanxi Province.According to the frequency characteristics generated by these incentives,the main influence factors of the vibration of the fan bridge caused by the original fan blades were explored.By analyzing the vibration signal,the main influencing factors of the vibration of fan bridge are explored according to the frequency characteristics.The test results show that the excessive vibration of the bridge is caused by the interference force caused by the fan eccentric mass.During the operation of the fan,the phase of the sensor at the middle of the bridge alternates positively and negatively,and the fan shaft produces a sway,which is inconsistent with the expected horizontal vibration of the bridge.In order to verify the rationality of the above analysis,the finite element analysis of the bridge frame was carried out,and the results are consistent with the above conclusions.Through the forced vibration test and hammer test of the fan bridge,it is found that the maximum frequency value of the vibration of the fan bridge caused by eccentric mass is far away from the natural vibration frequency of the fan bridge,and will not cause the resonance phenomenon of the fan bridge.Therefore,the vibration of the fan bridge caused by eccentric mass is only related to the static stiffness of the fan bridge.The test results will provide a basis for the design of beam bridge and the avoidance of vibration caused by fan eccentricity.…”
