APPARATUS FOR MEASURING DISPLACEMENT AMOUNT AND APPARATUS FOR MEASURING DISPLACEMENT AMOUNT OF DROP FORM IMPACT-TESTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a displacement amount-measuring apparatus having a mobile body and an optical laser displacement gage for measuring a dynamic displacement of the mobile body which has a wide displacement range where a move amount of the mobile body can be measured and has a high measurement resolving power for a move distance (displacement amount) for every predetermined time of the mobile body.;SOLUTION: The apparatus has a mobile body, an inclined jig 1 set to the mobile body and having an inclined face U with a predetermined inclination in a move direction of the mobile body, an optical laser displacement gage 2 for measuring a distance to the inclined face U in accordance with a movement of the inclined jig 1 for every predetermined time, and an operation means 7 which calculates a difference of adjacent distances to the inclined face U for every predetermined time which are measured by the optical laser displacement gage 2 in accordance with a movement of the mobile body from one point to another point, multiplies each difference by a proportion coefficient corresponding to the predetermined inclination of the inclined face, and calculates a displacement amount for every predetermined time of the mobile body.;COPYRIGHT: (C)2001,JPO
