Original abstract
This article focuses on the experimental contact area evaluation. Test rig is designed in order to investigate the piston/cylinder liner contact. The conducted experiment is based on the principle of electrical contact resistivity between two tested machinery parts. The measured results are compared with different contact model theories. The computational simulation uses precomputed database of contact pressure and contact area depending on separation distance of surfaces. This simulation is solved by Multibody System (MBS) enhanced by the user-written FORTRAN subroutine. The results of experiment and simulations are discussed.
Czech abstract
Tento článek se zaměřuje na experimentální ověření kontaktní plochy. Testovací sestava je navržena s ohledem na výzkum kontaktu mezi pístem a vložkou válce. Provedený experiment je založen na principu rezistivity elektrického kontaktu mezi dvěma testovanými strojními součástmi. Výsledky z měření jsou porovnány s výsledky z několika různých výpočetních modelů. Výpočetní simulace využívá databázi předpočítaných kontaktních ploch a tlaků v závislosti na oddělení dvou povrchů. Simulace je řešena pomocí Multibody Systému (MBS) rozšířeného o uživatelsky psanou funkci v jazyce FORTRAN. Výsledky simulací a experimentu jsou rozebírány.
