【摘要】：面向大型薄壁構(gòu)件自尋位加工檢測(cè)一體化測(cè)控原理,研發(fā)了一種小型化多維壓電力傳感器并進(jìn)行標(biāo)定研究。分析靜態(tài)標(biāo)定時(shí),偏載對(duì)壓電傳感器多維力測(cè)試精度的影響。通過(guò)對(duì)靜態(tài)標(biāo)定加載有偏差時(shí)傳感器受力的理論推導(dǎo)得到,加載偏差使傳感器的轉(zhuǎn)換系數(shù)改變,導(dǎo)致向間干擾補(bǔ)償系數(shù)失真,影響了橫向干擾輸出,降低了測(cè)試精度;分析了偏載程度對(duì)傳感器測(cè)試精度的影響,提出了衡量加載點(diǎn)偏差程度的判別方法,發(fā)現(xiàn)微小加載偏心帶來(lái)的附加干擾會(huì)超出傳感器自身向間干擾指標(biāo)規(guī)定的5%;針對(duì)機(jī)械連接偏載不可避免事實(shí),找到了克服偏載對(duì)轉(zhuǎn)換系數(shù)影響的輸出比例歸一化法,將向間干擾降到5%內(nèi)。
[Abstract]:In this paper, a miniaturized multidimensional pressure power sensor is developed and calibrated for the integrated measurement and control principle of large thin-walled components. The influence of bias load on the precision of multidimensional force measurement of piezoelectric sensor is analyzed. Through the theoretical derivation of the sensor force when the static calibration loading has deviation, it is concluded that the load deviation changes the conversion coefficient of the sensor, which leads to the distortion of the compensation coefficient of interdirectional interference, affects the lateral interference output, and reduces the testing accuracy. In this paper, the influence of the degree of bias on the precision of sensor testing is analyzed, and a method to judge the deviation of loading point is proposed. It is found that the additional interference caused by the micro-load eccentricity will exceed the 5 points stipulated by the sensor's own inter-directional interference index, aiming at the inevitable fact of the mechanical connection bias load, the output proportional normalization method is found to overcome the influence of the bias load on the conversion coefficient. Reduce the interferences to less than 5%.
