Abstract

This paper concerns the development of an entirely new force sensor called Gyroscopic Force Measuring System (simply called GFMS) for measuring a force vectorially. In a previous paper, the dynamical characteristics and the error analysis of the GFMS for measuring a force vector in 3-dimensional space were examined using numerical simulations. The results of this work are directly applicable to design and construction of the GFMS. In this paper, the GFMS is constructed by a gyro-rotor used a miniature rate-gyro for aircraft instrument and mechanical parts together. In order to verify the principle of the GFMS, our prototype GFMS made on first trial is able to measure the only one component of a force vector, excluding servomechanisms to estimate angles of incidence. The feedback gains are selected somewhat arbitrarily, but the fundamental experiments show that the force less than 0.3 N can be measured by the GFMS. This suggests the possibility to measure a small force range useful for air-flow distribution in an air-conditioned room as an example of expected applications. No doubt the experimental results are to be released in a future imeko_proceedings.
