等幅动态力校准.非共振单轴向动态检验系统的校准和验证.方法 - In the study of rotor system , sources of self - exciter vibration ( e . g . , asymmetric bearing stiffness and non - asymmetic clearance in labyrinth seals ) have been identified and extensively analyzed by investigators . however , the rotor dynamic forces due to clearance in turbines and compressors have received little attention
在对转子系统的研究中,人们关注更多的是对系统中多种自激振动源(不对称轴承刚度、迷宫密封中的非轴对称间隙等)的分析、识别和研究,但对于涡轮机和压缩机中由于非轴对称间隙而导致的转子动态力,人们却很少关注。 - The disease in jaw surface will be drop the bite force ; the bite force in the patient who disease in temporal jaw joint descent obviously than normal person ; serious mistake in join deformity , the acute damage in the area arthritis can also drop the bite force evidently ; compare to normal children , wenneberg fund that the bite force lower and the duration of the biggest bite force shorter in the children who fall ill of the chronic arthritis ; the bite force also be used in appraise of the recovery condition in surgical operation 、 disorder in jaw arthritis and the serious bone offset in bite lopsided etc . some materials , it will be produce polarization phenomenon inside when suffered some force in certain direction , at the same time , it produce opposite electric charge in two of the surface ; and resume to the station of on - electrification when removed the outside force ; change the direction of the outside force , the polarity of the electric charge also be changed , this kind of phenomenon is called as “ piezoelectric effect ”
本文设计了石英晶体压电传感器,以它作为传感元件把咬合力信号转变成电信号;利用ts5860型准静态电荷放大器把传感器的电荷信号转变成电压信号;选用usb7822数据采集卡,编写该数据采集卡的驱动程序,采集该电压信号并送到计算机里;编写labview程序对该信号进行处理,得出咬合力值和咬合力曲线,并把测量结果以电子表格的形式保存,以便做进一步的分析和研究。通过对该测量仪的静态标定、动态标定、温度漂移标定以及实际测量试验,证实了本测量仪具有较高的灵敏度、受动态力和温度变化的影响比较小、能实时地显示咬合力曲线和较准确地显示咬合力值,满足了咬合力测量的要求。
