Abstract
1. Способ измерения кривизны длинномерного объекта, заключающийся в том, что для измерения кривизны на базовом продольном участке объекта длиной 2t и максимальной кривизны на всю длину объекта, используются датчики (оптические, индуктивные, емкостные, лазерные и т.п.) расстояний до объекта, отличающийся тем, что обеспечивается независимость измерений от поперечного смещения или вибрации объекта и требует для своей реализации log2(L/t)+2 датчиков, где L - длина объекта; t - половина базового расстояния, при этом, погрешность измерения останется неизменной при любой длине объекта измерения. ! 2. Устройство для измерения кривизны длинномерного объекта, содержащее лазерные триангуляционные датчики, отличающееся тем, что датчики расположены между собой на расстоянии (t, t, 2t, 4t, 8t, 16t…), где t - половина базового расстояния для измерения кривизны. 1. A method for measuring the curvature of a long object, which consists in using sensors (optical, inductive, capacitive, laser, etc.) of the distance to the object to measure the curvature in the base longitudinal section of the object with a length of 2t and the maximum curvature over the entire length of the object , characterized in that the independence of measurements from lateral displacement or vibration of the object is ensured and requires for its implementation log2 (L / t) +2 sensors, where L is the length of the object; t is half the base distance, while the measurement error will remain unchanged for any length of the measurement object. ! 2. A device for measuring the curvature of a long object, containing laser triangulation sensors, characterized in that the sensors are located at a distance (t, t, 2t, 4t, 8t, 16t ...), where t is half the base distance for measuring curvature.
