Unbalance Fault Identification of Helicopter Rotor Using Support Vector Machine
摘要
Abstract
A method is presented for diagnosis of helicopter rotor unbalance by using support vector machine (SVM).A diagnosis model based on SVM is established and a model test is conducted on the rotor unbalance composed of blade mass unbalance, blade pitch unbalance and trailing edge flap unbalance.The vibration signals from the rotor test are acquired and analyzed.The SVM-based diagnosis model is employed to identify the rotor unbalance faults and compared with the diagnosis model based on RBF neural network.The results show that the SVM-based diagnosis model is effective in diagnosing the unbalance faults of helicopter rotor with small samples.关键词
