Static loading test device for missile wing

Abstract

The invention belongs to static test devices for aerial bomb missile wings, and in particular relates to a static loading test device for a missile wing. The static loading test device comprises a scissor fork mechanism, a cushion supporting column, a foundation platform, four groove-shaped guide rails, a movable lifting platform, a heavy block, a force-bearing soft hoisting belt, a taping belt, a missile wing clamp, a force-bearing vertical column, a fixed pulley, a winding drum mechanism, a speed reducer, an electric motor, an electric control cabinet, a steel wire rope and a guide wheel, wherein two groove-shaped guide rails are arranged on the upper surface of the foundation platform, and the scissor fork mechanism is arranged on the upper surface of the foundation platform by virtue of two supporting bases; cushion supporting bases are symmetrically fixedly arranged on the periphery of the upper surface of the foundation platform; the other two groove-shaped guide rails are arranged on the lower surface of the movable lifting platform, and the scissor fork mechanism is connected to the lower surface of the movable lifting platform by virtue of another two supporting bases; and the scissor fork mechanism is in rolling contact with the groove-shaped guide rails. The test device disclosed by the invention is simple to operate, and ensures that the operation strength can be effectively reduced, the number of operating staff can be reduced, and the cost and maintenance fees can be lowered.

Description

Technical field [0001] The invention belongs to a static test device for an air missile wing, and in particular relates to a static loading test device for a missile wing. Background technique [0002] The wing is a crucial part of the extended range of the aerial missile, and its wing surface bears aerodynamic uniform load during flight. In the ground test, the aerodynamic load must be simulated to assess the performance of the missile wing. Generally, according to the principle of bending moment equivalence, multi-point concentrated loading is used to simulate the wind load when the missile wing is deployed. [0003] At present, the most commonly used wing loading methods at home and abroad mainly include electro-hydraulic servo loading and crane hoisting standard weight suspension loading, etc. The former requires power oil source, electro-hydraulic servo valve, servo actuator, load sensor and data The acquisition and control system constitutes a closed-loop mode to complete th...

AI Technical Summary

Problems solved by technology

The electro-hydraulic servo loading device has a complex structure, high cost, inconvenient maintenance, and requires professionals to set parameters and operate; while the crane hoisting heavy block suspension loading device has a simple structure, but it needs to be disassembled repeatedly and coordinated by multiple people, which is time-consuming and laborious , especially when the operator is under the crane and the heavy block during operation, the safety hazard is relatively high

In addition, the impact or vibration load generated when the crane lifts the weight may be far greater than the test requirements, which will cause unnecessary structural damage to the wing test piece
