Manager -Analysis

 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 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.
• 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
