摘要通過對單擺運動方程的分析,得到了未知物體質心位置條件下測試復雜形狀剛體繞定軸轉動慣量的方法。The influence of the eccentricity mass moment, position of mass center and the bearing stiffness to the vibration characteristics of the rotor system is discussed in detail ; 3. to verify the exactness of fem and learn the principle of vibration of dredge pump further, the orbit of the rotor shaft of the pump in the dredger is measured, the measurement results show : the repeat of the orbit of the rotor shaft is very bad when dredge pump is in the dredging mud condition
模態分析確定了泥泵的振動特性(固有頻率和振型) ;諧響應分析確定了泥泵轉子軸在偏心力的作用下軸截面處的最大響應位移;研究了轉子軸的質心位置、軸承剛度和質量偏心矩對轉子軸振動特性的影響; 3 、採用軸心軌跡法,實船測量了泥泵軸工作時振動響應值。Including usign coordinate transformation method to deduce the uniform coordinate from the object coordinate to the photo coordinate, then setup the measuring error equation of apsse, this established the theory ground of usign the mont carlo method to analysis the error of apsse. there are errors from every tache of coordinate transform
由於建立機載光電跟蹤測量設備的測量誤差的位置傳遞方程是基於空間坐標變換的基礎上,從中心地平坐標繫到目標坐標系的變換涉及到幾十個環節,而每個環節都有誤差,其誤差的性質和大小直接影響對目標的定位測量。
