Parametric FEM modelling of multilayer castellated Canted Cosine Theta (CCT) magnets

The programs of air-operation and service in the aviation engineering - within this at light-aircraft too - takeplace according to rigorous regulations [6, 7]. There are such machine units and parts which regulation areincomplete, for instance such is the landing-shaft seating. We have developed a new maintenance modelbased on the traditional ones, which offers new information exchange modul for e.g. weak point reconstruction and uses paper based documentation and modern remote maintenance as well. Beside thenew model we have worked out a renewing solution of the often failed landing-gear leg support applyingfield and laboratory test and FEM modelling to fill up as an engineering example for the information modulof the new maintenance model.

The article presents modeling of human lumbar vertebra and it‘sdeformation analysis using finite elements method. The problemof tissue degradation is raised. Using the computer aided modelingwith SolidWorks software the models of lumbar vertebra(L1) and vertebra system L1-L4 were created. The article containssocial and medical problem analysis, description of modelingmethods and the results of deformation test for one vertebramodel and for model of 4 vertebras (L1-L4). Santrauka Straipsnyje aprašomas stuburo juosmeninės dalies slankstelio (L1) bei juosmeninės dalies slankstelių (L1-L4) sistemos modeliavimas ir tyrimas baigtinių elementų metodu (BEM). Sukuriamas erdvinis skaitinis modelis programinės įrangos SolidWorks aplinkoje. Sudaroma vieno ir keturių slankstelių (L1-L4) skaičiuojamosios schemos, modeliams suteikiama gniuždymo apkrova. Nagrinėjamas modelių deformavimas, esant gniuždymo apkrovai, kartu simuliuojant senėjimo procesų ir osteoporozės poveikį, kuris pasireiškia audinio silpnėjimu. Nagrinėjami ir lyginami trys atvejai: sveiko audinio apkrovimas, vidutinio osteoporozės lygio paveiktos slankstelių sistemos apkrovimas ir aukšto osteoporozės lygio paveikto modelio apkrovimas.
