    微耕機的噪聲測定及數據處置
    時間:2013-09-30 來源:本站 作者:管理員

     
     依據國標的測定位置和方法,中止靜態環境噪聲和駕駛員位置處噪聲的自動測定。將檢測數據傳送到計算機中,中止自動處置和分析。

     
     JB/T10266.2-2001微型耕耘機實驗方法中規則的噪聲測定方法有兩種:一是有靜態環境噪聲測定;二是駕駛員操作位置處噪聲測定。

     
     
    靜態環境噪聲測定:被試微耕機停放在測試場地中心,聲級計傳聲器置于微耕機驅動軸延長線上,距離被試微耕機縱向中心垂直面7.5m,離地高1.2m處,“A”計權網絡和“快”檔中止丈量。被試微耕機處于空檔狀態,發起機預熱抵達正常工作溫度后,在調速器所限定的最高轉速下運轉,記載此時的聲級計的最大讀數;

     
     
    駕駛員操作位置處噪聲測定:用聲級計的“A”計權網絡和“慢”檔中止丈量,將聲級計傳聲器安放在駕駛員的頭盔架上噪聲較大的一側,并使傳聲器朝前,與眼眉等高,距頭盔架中心平面250mm±20mm的耳旁處。中止測試時,微耕機呈最大設計耕深旋耕狀態,在每個檔位上,發起機油門全開,待其穩定后,讀取最大噪聲值并測定其行進速度。最后測定微耕機發起機油門全開、空駛速度為4-6km/h 檔位的最大空駛噪聲值和速度。
