Embodiment Construction

[0110] This embodiment takes a civil transport aircraft anti-skid brake control device as an example. The power supply is provided by the aircraft, and the electric signal of the wheel speed change is received to control the anti-skid brake pressure. The anti-skid brake control device can complete the functions of normal landing anti-skid brake control, wheel-to-wheel protection, ground protection, and wheel anti-rotation brake after the aircraft takes off.

[0111] A control board and a recording board are installed in the anti-skid brake control device, two circuit boards in total. The analysis object is the vibration model of the antiskid brake control device established by software.

[0112] The calculation conditions required in this embodiment are:

[0113] 1 The software used:

[0114] 1) Drawing three-dimensional geometric figure software: CITIA V5R18;

[0115] 2) Modeling software: Hypermesh / 10.0;

[0116] 3) Analysis software: NASTRAN2008r1;.

Abstract

The invention discloses a method of determining an anti-skid brake control device vibration weak link. The anti-skid brake control device vibration weak link is determined through a computer technology, and a design improvement proposal is brought forward according to the determined vibration weak link. The method of the invention has the beneficial effects that the energy consumption is low; test samples for the anti-skid brake control device are saved; and the energy-saving and consumption-reducing effects are obvious.

Description

technical field [0001] The invention relates to the field of vibration failure analysis of civil transport aircraft electronic products, in particular to a method for determining the vibration weak link of an anti-skid brake control device by using computer technology. Background technique [0002] The antiskid brake control is an electronic product in the aircraft braking system. [0003] The working principle of the anti-skid brake control device is to receive the electrical signal of wheel speed change transmitted by the wheel speed sensor, and to control the brake pressure during the landing anti-skid braking process according to the electrical signal, which can complete the normal landing anti-skid brake control and the take-off line brake control. , Inter-wheel protection pressure control, main engine wheel ground protection control, and various control functions of the wheel stop brake after the landing gear is retracted. [0004] The anti-skid brake control device i...
