SUPPORT MECHANISM FOR MULTICHANNEL SENSOR WHICH IS ROBUST AGAINST THERMAL EXTERNAL DISTURBANCE

摘要

PROBLEM TO BE SOLVED: To obtain a support mechanism for a displacement sensor such that uncertainty in the measurement result is minimized, when a measurement system in which the plurality displacement sensors having unknown temperature characteristics are combined is designed.;SOLUTION: The support position for the displacement sensor is defined so that a neutral surface of an object to be measured is at approximately the center of the measurement range of the plurality of displacement sensors. A jig for supporting the mutual position/posture of these displacement sensors employs a material and a structure such that the effect of the thermal displacement due to the effect of temperature variation can be managed or negligible, and supports it at the displacement sensor support position.;COPYRIGHT: (C)2005,JPO&NCIPI
