Simulation of the durability of conceptual solutions for piston assemblies, presentation of results and proposal for improvements
3.2 Main tasks
Independent execution of finite element analysis (FEA) and durability of conceptual solutions for pistons, piston assemblies and possibly adjacent components
Recommendation of improvements for piston design (geometry, pin bore and skirt profiles) and cooling options
Participation in the development team (application engineering, design, test bench) and communication of simulation results
3.3 Subtasks
Determination of the loads and boundary conditions based on the customers statement of requirements (SOR) and the product functional specification sheet (PFS) together with application engineering (AE)
Extraction of the relevant load cases from a set of pressure curves if provided by the customer
Creation of the FEA model based on a CAD design: mesh generation, definition of sets and surfaces, contact definitions, loads and boundary conditions for the following components: piston, ring carrier, cooling gallery, pin, bushing, connecting rod, connecting rod bushing, cylinder, piston rings, cooling jet
Definition of the profiles for pin bore, skirt and lands
Morphing of FE meshes for independent geometry modification
Calculation of the temperature field of the piston assembly and the heat flow over the system boundaries
Calculation of the stresses and deformations of the piston assembly for different load cases
Calculation of the durability of the piston assembly based on the stresses and temperatures
Independent improvement of piston assemblies by profile optimization and minor geometry modifications by morphing
Creation of simulation reports with detailed investigation of all relevant locations of the piston assembly. Submission of these reports into an internal approval process.
