Torque Sensor choose strain gage type, the choice of the transmission mode shaft formula, and then four strain gauge make full bridge, then connect leading-out wire to four slip rings. Slip rings rotate with the axis. Electric signal transmitted to the PCM data acquisition system through brush. Taking into account the equipment used in the fields of the strain gauge the diameter, Rated torque less than 100 Nm fixation of a transmission shaft can be measured. The design references the previous design, and has an improvement, afterward with the relevant content of the references and appendices. As the design process through the three and greatly improved its service life and maintainability. Calibration device design mainly to the problem of how to feed one-end connected with spline and fixed on experimental stage with bolt and the other connected to spend bond with the loading lever rotation together, in this way have reversed, and test its axis torque, Drawing calibration curve. Key words: strain gages-torque sensor, slip ring, PCM3132 data acquisition system, calibration device 目 錄 第一章 前言.......................... ..................1 第二章 概述 ............................................3 第三章 扭矩傳感器方案分析 ..............................4 §3.1用電力測(cè)功器測(cè)扭矩.............................. 4 §3.1.1直流電力測(cè)功器測(cè)量扭矩..................... 4 §3.1.2交流電力測(cè)功器測(cè)量扭矩..................... 5 §3.1.3電渦流測(cè)功器測(cè)量扭矩....................... 5 §3.2 用扭矩儀測(cè)扭矩............................ ..... 6 §3.2.1電阻應(yīng)變片式扭矩儀......................... 6 §3.2.2相位差扭矩儀............................... 9 §3.2.3 頻閃觀測(cè)式扭力計(jì).......................... 10 §3.2.4 鋼弦式扭矩儀.............................. 11 §3.3 輔助裝置..................................... 12 §3.3.1傳輸裝置分析..............................12 §3.3.2 數(shù)據(jù)分析與采集系統(tǒng).........................12 第四章 設(shè)計(jì)計(jì)算及結(jié)構(gòu)分析........ .. ..................14 §4.1 零部件的設(shè)計(jì)計(jì)算...............................14 §4.1.1 離合器軸上貼應(yīng)變片處直徑的確定.............14 §4.1.2 離合器軸和變速器一軸矩形花鍵連接長(zhǎng)度的計(jì)算.14 §4.1.3 一軸上薄弱截面強(qiáng)度校核計(jì)算................15 §4.1.4 電橋輸出電壓的計(jì)算.........................15 §4.1.5 標(biāo)定裝置力和扭矩曲線圖.....................16 §4.2 零部件的結(jié)構(gòu)特點(diǎn)及加工工藝性分析...............18 §4.2.1測(cè)量裝置.........................18 §4.2.2標(biāo)定裝置.........................18 第五章 結(jié)論....................................... ....20 參考文獻(xiàn)...............................................21 致謝...................................................22 III
