採用特徵分析法計算了兩種減擺器連接形式的直升機地面共振穩定性。Among others, one method to solve this problem is to install lead - lag dampers. the conventional configuration for installing dampers is to put them between blades and hub. in 1990s, eurocopter began to use the inter - blade dampers in ec155 which means to put every damper between two adjacent blades
傳統的減擺器布置是槳葉-槳轂式;上個世紀90年代，歐直公司開始在ec155上使用葉間減擺器，減擺器不是布置在槳葉和槳轂之間，而是布置在相鄰兩片槳葉之間。By using the method of transfer matrix, the dynamic model of the driving shaft vibration of swing movable teeth reducer is built. the calculation formula for natural frequencies of the flexural vibration of the driving shaft is derived
應用傳遞矩陣法，建立了擺動活齒減速器輸入軸振動的動力學模型，導出了輸人軸橫向彎曲振動的固有頻率的計算公式。The flight test of ec155 tells us that inter - blade dampers can work very well in stabilizing the system ; another advantage of this configuration is it can make the hub system simpler and reduce the drag of air to the hub which is very important for helicopters with 4 or more than 4 blades
Ec155的飛行試驗證明，這種減擺器布置方式對提高穩定性效果明顯;這種布置方式的另外一個優點是可以簡化槳轂，降低其氣動阻力，對多槳葉（四片和四片以上）直升機有重要意義。To reduce the weight of the whole reducer, the fea software ansys is adopted for the shape optimization design of the ring - plate in the double crank four ring - plate cycloidal pinwheel reducer and a good result is achieved
