| 為了實現(xiàn)某型掠海恒高拖靶系統(tǒng)的高度控制功能,設(shè)計了舵機(jī)執(zhí)行機(jī)構(gòu)和舵回路控制電路。采用螺旋滑動絲杠傳動機(jī)構(gòu),確定了牙形角、公稱直徑和導(dǎo)程等參數(shù),并計算了螺母和螺紋的長度,驗證了機(jī)構(gòu)自鎖條件;通過對減速比的計算,選擇了合適的減速箱型號;通過對電機(jī)功率及速度常數(shù)的計算,參照電機(jī)樣本數(shù)據(jù)表資料,完成了電機(jī)的正確選型,并進(jìn)行了指標(biāo)驗算;設(shè)計了以L292功放模塊為直流電機(jī)驅(qū)動器的舵回路控制電路。實際使用表明設(shè)計合理,各項性能指標(biāo)滿足要求。 |

| A servo executing agency and the rudder loop control circuit design was designed to achieve height control of a certain sea-skimming constant high tow target system.Spiral sliding screw drive mechanism is to determine the tooth-shaped angle,nominal diameter and lead,etc.Then verifying the institution's self-locking conditions by calculating the length of the nut and threaded.Next,the deceleration box marque was determined by calculating the reduction ratio.At last,motor's marque was determined by motor power and speed constants company with reference of sample data sheet information and complete the indicators checking.And the L292 power amplifier module was choosed as the rudder loop control circuit of DC motor drives.In conclude,actual use demonstrate its rightness and surely meet the requirements of the performance. |
