Structural Design of Ramp in Aluminum Alloy for ACV

摘要

It is very important for ACV to keep its overall weight down to a practical minimum because of its high-speed feature. As one of the most important structure, the design of ramp is also a very important factor which affects the structure weight. After comparing structural design in aluminum alloy with B steel, aluminum alloy is adopted to be the material of the ramp. After that, Multi-analysis of link means between hinge 、ramp and hull is also given. As a result, weldable aluminum alloy is also used in hinge based on aluminum alloy ramp. To insure the strength of ramp in aluminum alloy and hinge 、pintle, finite element method(FEM) is carried out in further checkout calculation. Lastly, because of the difference between ramp in aluminum alloy and in steel, and to get rid of the design risk, model test are taken to get the stress and displacement of the ramp under static load and the stress under dynamic load and the test result give a good proof to the strength of the ramp and hinge. All the design and analysis processes provide a useful reference for further research and wide application of ramp and hinge in aluminum alloy for ACV.
