Abstract: PURPOSE: To make it possible to detect large force by separating partial pressures in two or three orthogonal directions, by constituting a small-size measuring device by using a shearting stress detection strain gauge that can separate and detect partial pressures in two orthogonal directions.  
     CONSTITUTION: Center 0 of receiving board 10 of a platform balance is taken as an origin to provide right-left, up-down and front-back X, Y and Z axes. In this case, left and right external parts 12 and 14 of the Z axis are support tables and center vertical sections 20 and 22 of their boundary parts 16 and 18 are stress concentration surfaces. Strain gauges 36' and 36", and 38' and 38" that stress concentration sections 20 and 22 cross at 45° centering vertical lines of intersection with a stress concentration hole wall or side wall of front-back plate 10. As a result, vertical force operates upon receiving plate 10 and shearing force W operates upon the strain gauge part, so that while gauge pieces 36' and 38" are compressed, 36" and 38' will be elongated. For this purpose, when a strain gauge bridge using 36' and 38", and 36" and 38' as diagonal sides is formed, an unbalanced voltage due to shearing strain is applied, so that the shearing force in direction Y will be detected.

Title: Vibro-preventive device with anisotropic leaf spring
Inventor: HIROMATSU TAKESHI
IPC: F16F15/00
Filed: 1987-07-03
Abstract: PURPOSE:To prevent generation of transverse dislocation in a large scale by making a vibro-preventive spring through folding of a sheet into bellows, setting the anisotropic characteristic and spring stiffness, and supporting a vibration excitor or a vibration receiver by vibro-preventive springs arranged in two directions in right angle to each other. CONSTITUTION:Ratio of the natural frequency of a vibro-preventive spring 5 in its plum direction to the one in horizontal direction can be calculated from the width of folding A in cm, the number of times of foldings N, depth L in cm, folding angle theta deg., plate thickness in cm, and properties of the material. The spring is given a form such that this ratio of natural frequencies becomes 50-100 as ideal. That is, this vibro-preventive spring 5 responds flexibly to externals forces with elastical deformation of each folded part and deflection of each folding piece as long as it corners the vertical direction. In the horizontal depth direction, a great resistance will be encounted with the material characteristics of the sheet and the depth dimension L. These anisotropic leaf springs 5 are installed in the directions in right angle to each other and support a vibration excitor or a vibration receiver, so that transmission of the vertical vibration is damped mildly and vibro-suppressed, and the horizontal displacement is counteracted strongly to prevent transverse dislocation.
