Tooth load display device of toothed belt, tooth load display method of toothed belt, and program

摘要

PROBLEM TO BE SOLVED: To display a calculation result of a tooth load that is predicted using a finite element method analysis as a graph which can be easily visually recognized.SOLUTION: By a finite element method analysis, a stress of truss element at a plurality of division parts provided between a plurality of tooth parts is outputted (S2), based on a stress difference between adjoining division parts, an absolute value of a tooth load at a tooth part between the division parts is calculated (S3), a stress at a front division part is subtracted from a stress of a rear division part along belt's advancing direction in the adjoining division parts, and positiveness/negativeness thereof is calculated as a direction of the tooth load at the tooth part between the division parts (S4), one of nodes of the truss element present between adjoining division parts is calculated as an original point of the tooth part between the division parts (S5), and an absolute value and direction of the tooth load at the tooth part between the adjoining division parts are displayed as a vector extending from the original point (S8).SELECTED DRAWING: Figure 7
