Problems solved by technology

[0006] The aircraft simulation experiment device disclosed above is mainly for flight performance testing under a single attitude or coupling of three attitudes, it is difficult to simulate the structural performance of the aircraft in a large overload environment, and it is impossible to continuously simulate the overload of the aircraft
The rope traction parallel robot and the centrifuge simulation device disclosed above can realize the large overload maneuver simulation of the aircraft, but the rope traction device is limited by the slackness of the traction rope, and the movement space is limited, and the centrifuge flight overload simulation is mostly aimed at a certain attitude of the aircraft The static overload simulation below is a steady-state acceleration test device, which cannot simulate the acceleration change rate, and it is difficult to realize the complex dynamic overload simulation process

Abstract

The invention discloses a high-dynamic centrifuge overload simulation test device. The high-dynamic centrifuge overload simulation test device comprises a first freedom degree device for providing static overloads for a test piece, a second freedom degree device for providing the yaw rotating movement for the test piece, and a third freedom degree device for providing the rolling rotating movementfor the test piece. The test piece is arranged on the third freedom degree device, and the second freedom degree device is used for freedom degree control of the third freedom degree device. The first freedom degree device is used for freedom degree control of the second freedom degree device. According to the three-axis acceleration of a centrifugal machine resultant acceleration simulation aircraft, specifically, through rapid changing of the main arm system rotation speed, rapid changing of the centrifugal machine resultant acceleration value is achieved. Through rapid changing of the rotation direction of the second freedom degree device, and rapid changing of centrifugal machine resultant acceleration in the aircraft three-axis projection direction is achieved; and accordingly dynamic simulation of aircraft test piece three-axis acceleration changes is achieved, and continuous rapid dynamic changing overloads are accurately provided.

Description

technical field [0001] The invention belongs to the technical field of simulation test devices, in particular to a high dynamic centrifugal overload simulation test device. Background technique [0002] In order to verify whether the aircraft has good flight performance in actual flight, it is necessary to test the performance of the aircraft on the ground. The high dynamic flight environment is a flight mode in which the structure of the aircraft is under severe stress. It is necessary to test the structure of the aircraft in this environment. Performance, providing effective and reliable technical indicators and test data for actual air flight. [0003] The actual flight process of a highly dynamic aircraft often involves various factors such as the three-axis overload acceleration and the acceleration rate of change, but the current aircraft performance test devices are mostly concentrated in the following two aspects: [0004] In terms of independent simulation testing ...
