Abstract

The invention discloses a wall collision prevention method of a double-flight refueling wind tunnel test supporting device. The wall collision prevention method comprises the steps: building a positive motion equation of a supporting device, and determining the joint space of each joint in the supporting device; then selecting a random value set in the joint space, wherein the random value set comprises a plurality of random values in one-to-one correspondence with the joints, inputting the random value set into the positive motion equation, and calculating the position of an end execution point of the supporting device defined by the random value set; and repeating the steps of defining the random value set and calculating the position of the end execution point for multiple times so as to obtain the position of the end execution point under multiple conditions; and drawing a work space cloud chart according to the positions of all the end execution points; finding out a point of which the position of an end execution point exceeds the position of the wind tunnel space in the work space cloud atlas, deleting the random value set corresponding to the point, and taking the remainingrandom value group as an experimental parameter set, thereby guaranteeing that the end execution point does not collide with the side wall of the wind tunnel theoretically.

Description

technical field [0001] The present application relates to the technical field of aerial refueling, in particular to an anti-collision method for a support device in a wind tunnel test for refueling of two aircraft. Background technique [0002] The support device for aerial refueling needs to be tested in a wind tunnel before it is actually applied to verify whether it can meet the requirements of support strength and other conditions during the high-speed flight of the aircraft. During the wind tunnel experiment, the support device needs to continuously adjust its posture to simulate the cooperation between the oil tanker and the oil receiver in practical applications. During the process of adjusting the position of the support device, it is easy to collide with the side wall of the wind tunnel. The collision not only affects the normal progress of the experiment, but may even damage the support device and the wind tunnel. [0003] Therefore, how to avoid the collision bet...
