Finite Element Dynamic Analysis of the Shafting of Transmission-Laser-Scanning-Emitter

Abstract:

The transmission laser-scanning diameter-measurement system uses the parallel laser-scanning principle to achieve high-precision measurements of radial dimensions of shaft parts. The transmission laser-scanning emitter is a mechanical scanning device of which scanning accuracy has a significant impact on stability of the measurement system. The dynamic model of the emitter's shaft rotor is established. Dynamic performances according to variant parameters are derived by finite element analysis simulation. Characteristics of high-speed-rotors with different structures, such as vibration mode and natural frequency, are summarized to provide theoretical basis for shafting design.
