BELT TENSION CALCULATING PROGRAM, BELT NATURAL FREQUENCY CALCULATING PROGRAM, AND METHOD AND DEVICE FOR SAME

摘要

A more accurate tension of a belt or a more accurate target natural frequency of the belt when the belt tension is adjusted is determined. A belt tension calculating program includes: allowing a computer to receive a natural frequency of a belt and a span, perform calculation for determining the tension of the belt using a predetermined expression, based on the natural frequency, the span, and a unit mass of the belt read from a memory, and display the tension on a display. In a case where the span is within a predetermined range corresponding to the belt, the predetermined expression is corrected so that an error caused by a bending stiffness of the belt is reduced.
