More Information
Summary:The invention relates to the field of engineering machinery, and discloses a method and device for judging the safety of the rotation direction of an arm support, and engineering machinery. The methodcomprises the steps: acquiring the gravity center of the engineering machinery; acquiring a bearing area of the engineering machinery; determining a nearest edge, wherein the nearest edge is the edgewith the shortest distance from the gravity center in a polygon formed in the bearing area; determining a judgment angle, wherein the judgment angle is an included angle between the nearest edge anda connecting line of the stability center and the gravity center of the engineering machinery, the nearest edge is provided with a direction, the direction of the nearest edge is consistent with the rotation direction of the arm support, the connecting line is provided with a direction, and the direction of the connecting line is from the stability center to the gravity center; and based on the judgment angle, judging the s
