【摘要】：時柵是近幾年發(fā)展起來的一類新型位移傳感器,通過建立雙坐標系巧妙的運用時間測量空間。其中,寄生式時柵角位移傳感器是時柵團隊針對末端難以安裝傳感器而研發(fā)的新產(chǎn)品,采用旁置安裝的方式實現(xiàn)對末端件(本課題以齒輪為研究對象)的旋轉(zhuǎn)角度進行測量。寄生式時柵具有精度高、成本低、體積小、質(zhì)量輕、抗強干擾等優(yōu)點,在極端和特殊環(huán)境的應(yīng)用具有極大潛力。寄生式時柵角位移傳感器采用旁置的方式安裝傳感測頭,在帶來方便的同時也帶來了安裝問題。其原理上是利用被測齒輪的齒槽等分性,齒輪旋轉(zhuǎn)時實現(xiàn)磁導調(diào)制來完成角位移到電行波的轉(zhuǎn)換,進一步由后續(xù)信號處理系統(tǒng)解算出角位移值。因此,當傳感測頭的安裝狀態(tài)發(fā)生變化時,會不同程度的改變磁導調(diào)制的規(guī)律,影響傳感器的性能給角位移測量帶來誤差。本文作者從理論推導、仿真分析和實驗驗證三個方面對寄生式時柵傳感測頭安裝狀態(tài)測量方法進行研究,取得了如下幾個方面的成果:(1)深入研究寄生式時柵的原理和結(jié)構(gòu),分析寄生式時柵傳感測頭安裝狀態(tài)變化對傳感器性能的影響;(2)從理論上分析寄生式時柵傳感測頭安裝狀態(tài)變化到傳感單元感應(yīng)信號的耦合過程,并推導出理論表達式;(3)借助MATLAB進行數(shù)值仿真,觀察傳感測頭安裝狀態(tài)變化時傳感單元感應(yīng)信號變化的規(guī)律,并找出測量傳感測頭安裝狀態(tài)變化各個分量的方法;(4)利用有限元電磁仿真軟件,對理論分析進行驗證,確定了參考點的選擇,并對設(shè)計的安裝狀態(tài)測量方法進行驗證和優(yōu)化;(5)搭建實驗平臺進行實驗研究,分別對傳感測頭安裝狀態(tài)對傳感器性能影響分析、參考點選擇和傳感測頭安裝狀態(tài)測量的方法進行實驗驗證,并對驗證結(jié)果進行分析討論。研究結(jié)果表明,通過在傳感測頭的各個傳感單元中嵌入獨立的感應(yīng)線圈,可以實現(xiàn)對寄生式時柵傳感測頭多自由度安裝狀態(tài)變化的分離測量。
[Abstract]:Time grating is a new type of displacement sensor developed in recent years. Among them, the parasitic time-grid angular displacement sensor is a new product developed by the time-grid team, which is difficult to install the sensor at the end. The method of side installation is used to measure the rotation angle of the end piece (this subject is gear as the research object). The parasitic time grid has the advantages of high precision, low cost, small volume, light weight, strong interference resistance and so on, so it has great potential in extreme and special environments. The parasitic time grating angular displacement sensor adopts side-mounted sensor probe, which not only brings convenience but also brings installation problems. In principle, the angle displacement is converted from angle displacement to electric traveling wave by using the tooth slot equipartition of the measured gear, and the magnetic conductance modulation is realized when the gear rotates, and the angle displacement value is further calculated by the subsequent signal processing system. Therefore, when the installation state of sensor probe changes, the law of magnetic conductance modulation will be changed in varying degrees, which will affect the performance of the sensor and bring errors to the measurement of angular displacement. In this paper, the author studies the method of measuring the installation state of parasitic time grating sensor probe from three aspects: theoretical derivation, simulation analysis and experimental verification. The results are as follows: 1) the principle and structure of parasitic time grating are studied in depth. The influence of the installation state of the parasitic time grating sensor probe on the sensor performance is analyzed. (2) the coupling process between the installation state of the parasitic time grid sensor probe and the sensor unit inductive signal is analyzed theoretically. In addition, the theoretical expression "Xian3" is deduced. By means of MATLAB, numerical simulation is carried out to observe the change of sensing unit's inductive signal when the installation state of sensor probe changes. And find out the method of measuring each component of sensor probe's installation state change. (4) by using finite element electromagnetic simulation software, the theoretical analysis is verified, and the selection of reference point is determined. The experimental research is carried out on the experimental platform to verify and optimize the measurement method of the installation state of the sensor probe, and the influence of the installation state of the sensor probe on the performance of the sensor is analyzed respectively. The selection of reference points and the method of measuring the installation state of sensor probe are verified experimentally, and the verification results are analyzed and discussed. The results show that by embedding an independent induction coil in each sensing unit of the sensor probe, the separation measurement of the multi-degree-of-freedom installation state of the parasitic time-grid sensor probe can be realized.
