- Abstract:
- This paper introduces a new 'portable' angular exciter model developed in KRISS during last two years. Its development was successfully completed in 2010 such that most technical issues have been resolved and a product model is ready to be delivered to the industrial sectors. Interestingly, a new company being incubated in KRSSS emerged to make and distribute a final version of angular vibration exciters to the market. This paper introduces recent measurement and test results, such as the usable frequency range, the capacity of generating angular acceleration, harmonic distortion ratios, etc, carried out in the technology incubation stage supported by KRISS. One of the topics of the technology incubation project was to develop the portable angular vibration calibration system targeted to the market. Its tested technical performance indicators and specifications are in details presented in this paper. In summary, its inertia moment is designed to be less than 2 × 10-5 kg·m² and to cover not only the frequency range of 10 Hz to 1 kHz but also the peak angular acceleration of 2,000 randian/s² or higher.
