Turn Milling

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.

Using finite element method steady state and dynamic performance of a capillary compensated hydrostatic journal bearing have been investigated. For stability studies, the critical mass of the bearing system has been determined by Routh’s criterion. The locus of the journal center has been predicted by discretizing time and numerically integrating the equations of motion governing the journal bearing system.

One Micro-Electro-Mechanical System(MEMS) based actuator that fabricated by LIGA (Lithographie ,Galanoformung and Abformung) technology was designed to distinguish the change of the exterior condition. In order to prove whether the parts in the actuator intervene each other during motion, ADAMS software was utilized to simulate the motion. The rigid-flexible coupling dynamic modeling of the design was obtained by combining finite element method (FEM) with Lagrange equation, the mathematics modeling was solved with Gear method in ADAMS. The results showed that the MEMS-based actuator could move smoothly, and the simulated curve meets the intent.
