Original abstract

The paper provides description of FEM stress analysis of several landing gears for new Czech aircraft. In all loading cases, there is considered material and geometric non-linearity, contacts and friction between some parts of landing gear and carried out verification of analysis results with comparative testing. The structural tests of the landing gears of Zlín Z143-L, small GA and aerobatics plane and KP2U-Sova, an ultralight plane , were tested in the IAE laboratory. The structural test of nose and main landing gear of Aero Vodochody s new commuter were tested in test laboratory of Technometra Radotín, the Czech producer of landing gear.

Czech abstract

Článek popisuje napěťovou analýzu několika povozků letounů české výroby pomocí metody konečných prvků. Ve všech uvedených příkladech je uvažována materiálová a geometrická nelinearita, kontakty a vliv tření mezi patřičnými díly podvozku, je provedena verifikace vypočtených výsledků s odpovídající zkouškou. Pevnostní zkoušky podvozků letounu Z143-L a KP2U-Sova byly prováděny na zkušebně Leteckého ústavu. Pevnostní zkoušky příďového a hlavního podvozku letounu Ae270 ( Aero Vodochody ) byly prováděny na zkušebně výrobce těchto podvozků – Technometra Radotín, a.s.
