This work has been realized in cooperation with The Construction Office of WSK “PZL-KALISZ” S.A.” and is part of Grant Agree-ment No. POIR.01.02.00-00-0002/15 financed by the Polish National Centre for Research and Development. The project/research was financed in the ramework of the project Lublin University
of Technology – Regional Excellence Initia-tive, funded by the Polish Ministry of Sci-
ence and Higher Education (contract no. 030/RID/2018/19).
he article presents the results of numerical simulations using the FEM (Finite Element Method) of the engine
mount strength for mounting an aircraft diesel engine with opposite pistons called PZL-100. Four versions of the
mount prepared by aircraft engine producer WSK “PZL-Kalisz” company were analyzed. Tests were performed
in Catia v5 software in the Generative Structure Analysis module. The boundary conditions were engine gravity
force, propeller thrust force, and propeller torque. S235JR steel was defined as the material. A design grid with
tetrahedral elements with a single element size of 2 mm was used. As part of the simulation study, four structural
solutions for the test engine mounts were calculated in terms of strength. The results of stress maps and the mag-
nitude of deformation of the mount elements were compared. Based on the obtained results, one of the mount
versions was recommended for actual fabrication.
