【摘要】 采用解析法对航空发动机组主轴系在偏心条件下所引起的弯曲振动和扭转振动耦合特性进行了推理 ,并利用INV - 8型抗混滤波放大器、INV - 30 6DF型智能信号采集处理分析仪和DASP系统作了实验验证更多还原

【Abstract】 Using the method of analytics, this paper deduces the coupling characters of bending and torsional vibrations of the aero motor shafts under the situation of eccentricity. And it also validates the conclusion with experiment using the devices of COINV(INV-8?INV-306DF) and the DASP system.更多还原
