Embodiment Construction

[0022] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as figure 1 , figure 2 Shown is a kind of general-purpose aircraft vertical crash test device of the present invention, and it comprises: fixed bracket 1, test piece 4, impact platform 11, some guide cables 3, scale plate 7,9 and face scale plate 7, 9 placed cameras 8, 10.

[0024] The test piece 4 is fixed on the fixed support 1 by the suspension steel cable 2 . The height of the lowest point of the aircraft test piece 4 from the impact platform 11 is H.

[0025] The impact platform 11 is arranged on the ground and parallel to the fixed support 1 .

[0026] The number of guide cables 3 is preferably four, which are arranged between the fixed bracket 1 and the impact platform 11 and run through the test piece 4; furthermore, the guide cables 3 are vertically arranged with the fixed bracket 1 and the impact platform 11.

Abstract

The invention discloses a general-purpose plane vertical crash test device and a general-purpose plane vertical crash test method. The general-purpose plane vertical crash test device comprises a fixing bracket, a test piece which is fixed on the fixing bracket through suspension steel cables, a crash platform which is arranged on the ground and is parallelly opposite to the fixing bracket, a plurality of guide steel cables which are arranged between the fixing bracket and the crash platform and penetrate the test piece, a scale plate, and a camera which is arranged in a manner that the camera directly faces the scale plate. With the general plane vertical crash test device and test method provided by the invention, the stability of the attitude of the plane test piece in a free fall process can be ensured, and it can be ensured that the test piece cannot deviate from the guide steel cables in crash and bounce, and therefore, the safety of personnel and equipment can be guaranteed; and the scale plate and the camera are used in cooperation, and therefore, real-time recording of the deformation and displacement of the test piece in the crash process can be realized, and whether the test piece is tilted in the fall process can be verified. The general-purpose plane vertical crash test device and test method of the invention are advantageous in accurate test results, simple operation, safety and feasibility.

Description

technical field [0001] The invention belongs to the technical field of aircraft design, and relates to a test device and a test method, in particular to an aircraft vertical crash test device and a test method. Background technique [0002] In the vertical crash test of a general-purpose aircraft, the test piece needs to be hoisted to a certain height H in order to achieve the ground contact speed V required by the test piece, and the head of the test piece is vertically downward, and the free fall method is adopted. In the vertical drop test, how to keep the head of the test piece in a stable vertical downward position during the fall is the key issue in the drop test. In addition, after the test piece falls to the ground, its bouncing direction is difficult to predict, and there are safety problems for personnel and equipment. Contents of the invention [0003] The purpose of the present invention is to provide a kind of effective and feasible general-purpose aircraft v...
