TDM4.3-020-300-W0傳感器的結(jié)構(gòu)及工作原理 水中爆炸壓力傳感器的結(jié)構(gòu)如圖1所示。 該傳感器以具有壓電效應(yīng)的電氣石為敏感元件，內(nèi)部填充硅油，采用高絕緣密封膠進(jìn)行密封。工作時(shí)，將傳感器放入水下離爆炸源一定的距離，當(dāng)炸藥爆炸后產(chǎn)生的壓力通過(guò)水，以沖擊波的形式向各個(gè)方向傳播，電氣石晶體將感受到的壓力信號(hào)轉(zhuǎn)換成的電信號(hào)，從而實(shí)現(xiàn)能量的轉(zhuǎn)換。 2 傳感器的性能檢測(cè) 2.1 傳感器的靜態(tài)標(biāo)定 （1）標(biāo)定設(shè)備：TDM4.3-020-300-W0傳感器的校準(zhǔn)設(shè)備為JS-2500（250MPa）活塞壓力計(jì)；準(zhǔn)確度等級(jí)為0.02。 （2）標(biāo)定方法：采用加載法，每個(gè)傳感器預(yù)壓3遍后開(kāi)始校準(zhǔn)，校準(zhǔn)3次取平均值，按最小二乘直線法計(jì)算得出傳感器的靜態(tài)靈敏度、非線性靜態(tài)標(biāo)定結(jié)果見(jiàn)表1。 由表1標(biāo)定的結(jié)果得出：MCRI傳感器的非性為1.36％．靈敏度為26.12pC/MPa。 2.2 動(dòng)態(tài)標(biāo)定 （1）標(biāo)定設(shè)備：美國(guó)PCB公司913B02型水動(dòng)力脈沖標(biāo)定裝置（含內(nèi)裝電荷放大器的136A型標(biāo)準(zhǔn)傳感器）。 （2）標(biāo)定方法：采用比較校準(zhǔn)落球標(biāo)定法，將傳感器按照靜態(tài)靈敏度配置模塊式電荷放大器，然后，與標(biāo)準(zhǔn)傳感器同時(shí)安裝在標(biāo)定接頭上，將鋼球從不同的高度自由下落，撞擊高壓液壓裝置中的活塞，產(chǎn)生的半正弦波壓力（也是一種脈沖壓力）經(jīng)過(guò)液壓油傳遞給傳感器，以參考傳感器為基準(zhǔn)。將被校傳感器的曲線與標(biāo)準(zhǔn)傳感器的曲線進(jìn)行幅值和波形一致性的校準(zhǔn)，求得傳感器的動(dòng)態(tài)校準(zhǔn)非線和靈敏度。傳感器的動(dòng)態(tài)標(biāo)定結(jié)果見(jiàn)表2。 由表2的結(jié)果可以得出：傳感器的非線性為0.17％；平均靈敏度為1TDM4.3-020-300-W023.76mV/MPa。 由靜態(tài)和動(dòng)態(tài)標(biāo)定得到的傳感器的非線性值不一樣，這是因?yàn)楫?dāng)傳感器的絕緣電阻不是很高時(shí)，在靜態(tài)標(biāo)定中，由于加載時(shí)間較長(zhǎng)，傳感器會(huì)產(chǎn)生一定的零漂，從而影響傳感器的線性指標(biāo)；另外，動(dòng)態(tài)標(biāo)定使用的設(shè)備，由于密封的問(wèn)題，標(biāo)定只能到達(dá)29MPa的壓力，遠(yuǎn)低于量程上限，所以，動(dòng)態(tài)標(biāo)定的非線性比靜態(tài)標(biāo)定的非線性指標(biāo)高。 3 水池試驗(yàn) （1）試驗(yàn)條件：水池直徑為85m，深度為15m；爆炸源為RS211，重量為1.01kg；傳感器安裝深度為5m，離爆炸源水平距離為3m。 （2）試驗(yàn)方法：試驗(yàn)時(shí)，將研制的傳感器及測(cè)試系統(tǒng)與美國(guó)PCB公司的138型激波傳感器和專用的信號(hào)采集裝置同時(shí)進(jìn)行測(cè)量對(duì)比。試驗(yàn)波形曲線如圖2所示。傳感器的爆炸沖擊波能及氣泡能測(cè)試測(cè)試數(shù)據(jù)見(jiàn)表3。 TDM4.3-020-300-W0從傳感器的沖擊波能及氣泡能測(cè)試波形曲線，得到MCRI 5#，MCRI 6#的沖擊波形上升前陡峭，抗干擾能力強(qiáng)，與美國(guó)PCB公司生產(chǎn)的PCB138-1傳感器測(cè)量結(jié)果的比較，獲得的沖擊波波形基本一致?？傊?，由測(cè)試結(jié)果可以證時(shí)：獲得的沖擊波波形基本一致?？傊?，由測(cè)試結(jié)果可以證明：整個(gè)測(cè)試系統(tǒng)的動(dòng)態(tài)測(cè)試具有抗干擾能力強(qiáng)、強(qiáng)度高、測(cè)量壓力范圍寬。
