摘要
The mathematic models describing various joints of whole machine are founded to research dynamic performance of turn-milling center based on rigid-flexible coupling system. The various joint interfaces including the conical and cylinder contact, plane contact and fixed connection are regarded as flexible joints by using the spring and damping unit and the equivalent dynamic models of joint interfaces are built by finite element method based on different connection modes. Therefore, these mathematic models are used as references and foundations for research on dynamic performance of turn-milling center next stage.
