Technical Field

The invention relates to the technical field of wind tunnel tests, in particular to a steel wire rope clamp and application thereof.

Background

At present, the folding wings (rudders) of most folding wing missiles are in a passive structure, the missile wings (rudders) need to be folded and placed in a launching box (barrel), and the missile wings (rudders) automatically unfold and lock at the moment the missile launches out of the launching barrel. The folding angle of the missile wing in the launching tube directly influences whether the missile wing can be successfully unfolded to the locking position after being taken out of the tube.

Therefore, the purpose of carrying out the missile wing and air vane wind tunnel unfolding test of the folding wing missile is to determine the design states of the missile wing and the air vane (including the design states of a folding mechanism, a locking mechanism and the like), and to check and verify the unfolding performance of the determined design states under the conditions of a specified folding angle and an external wind speed.

When a folding wing (rudder) wind tunnel unfolding test is carried out, the folding wing (rudder) is generally fixed on a projectile body by adopting a constantan wire or a string wrapped with an ignition explosive package to simulate various folding fixing angles of the missile wing in a launching tube. After the wind speed in the wind tunnel reaches the set requirement, the constrainer wire is ignited to release the restraint of the folding wing (rudder), and whether the missile wing can be completely opened and locked is observed. However, the constantan wire has ductility, and cannot realize accurate fixation of the folding angle of the missile wing (rudder); when a wind tunnel experiment is carried out, along with the lifting of the wind speed, the torque generated by the folding wings is gradually increased, and the constantan wires and the ignition strings are likely to break in advance when the wind speed required by the experiment is not reached, so that the experiment fails. After the missile wing is folded, the distance between the edge of the missile wing and the missile body is very small, and the missile wing cannot be effectively fixed when the folding angle of the missile wing with large torque is fixed. Therefore, how to accurately and stably fix the folding angle of the missile wing (rudder) to improve the success rate of the test is a technical problem to be solved in the field.

The steel wire rope is woven by high-strength steel wires and has the advantages of high tensile strength, flexible length adjustment, low cost and the like. The steel wire rope is matched with the locking and releasing device to fix the angle of the folding wing, which is a good method. However, when the steel wire rope clamp is used for clamping the steel wire rope at present, point contact or line contact is mostly adopted, and the problems that a clamping surface is easy to damage, the steel wire rope slips due to insufficient clamping force, the size is large, the folding wing wind tunnel unfolding test small-space operation is not suitable and the like exist when a single steel wire rope is fixed.

In view of this, the invention is particularly proposed.

The specific shape and structure of the wedge 4 are not strictly limited; as shown in fig. 5 and 6, in one embodiment, the wedge 4 may be a semicircular wedge. It will be appreciated that the semi-circular wedge has a circular arc surface at the top end, a flat surface at the bottom end and a wedge surface at the head end, with the through slot 41 being disposed in the flat surface of the semi-circular wedge.
