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;.
