Job Description

Job Description

3.1 Mission

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 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.

Presentation of the simulation reports to application engineering and customers

Participation in customer meetings if required

Comparison of the simulation results with the engine test results

Carrying out the assigned project simulations in compliance with specified target deadlines

Carrying out priority planning for several project tasks assigned in parallel in accordance with Request for Engineering Services (RES) orders under consideration of specified deadlines

Further development of the simulation methodology to increase the speed of the process and the accuracy of the simulation results
