Research Abstract

The study conducted in 1994 is concerned with the following two subjects,
1) The effect of the dimensional error of the hinge on the mass and the dynamic rigidity
2) On the displacement detecting type balance with high sensitivity
1. The effect of the dimensinal error of the hinge on the mass and the dynamic rigidity
The experiments are repeatedly done on the effect of the dimensional error on the mass, using a prototype balance with dimensions of 54 high, 62 wide and 8mm thick.
(1) The fact that around 3/8 of the dimensional error in thickness contributes to the mass to be measured is confirmed in order to highten the dynamic rigidity.
(2) It necessities to make hinge stiff and reduce mass of reinforceing plate and the stage.
2. On the displacement detectig type balance with high sensitivity.
The manufactured fine balance with high sensitivity consists of 5 flat plates (dimensions : 50mm high, 12 thick and 50 wide) made of aluminum. In order to design a balance with high sensitivity, all the plates are combined in series. The facts made clear in this study are ;
(1) The displacement at the ideal point remains ideally unchanged regardless of the loading position. The actual displacement, however, changes in according with the location of loading, leading to the error of the mass to be measured.
(2) The balance concerned is too stiff to achieve the expected accuracy of 1/10,000. It is required to improve further more the sensitivity
(3) The balance necessities to be modified because of the torsional weakness.
