摘要
螺旋桨作为一高速旋转部件,由于制造和装配误差,造成螺旋桨在装机后重心和旋转中心不重合,以及各桨叶上气动力不完全一致,从而使螺旋桨在高速旋转过程中产生振动。文中讨论一种精确测量螺旋桨重点位置的方法,可为正确进行螺旋桨动平衡提供参考。
Because of the errors in manufacturing and reassembling, the barycentre of the propeller will deviate from its rotation centre, and the aerodynamic force brought from every blade is not exactly the same, these factors will make the propeller vibrating when it is in high-speed rotating. A accurate detection method of heavy spot on the propeller is proposed to provide a good reference for the procedure of propeller dynamic balance.
