Background

About Boris Bedic

Activity: • Experienced in team lead and coordination • Experienced in NVH simulation and analysis; both concept/layout and troubleshooting projects. • Experienced in automotive and non-automotive NVH projects Job responsibilities: • Team lead • Alignment of team workload distribution • Supporting of team colleagues and newcomers • Simulation setup and analysis of highly advanced prototype systems • Overall evaluation of results for concept projects and determination of problems on existing engines/structures with recommendations/requirements on possible/necessary design improvements to correspond with set criteria limits. • Proactively testing (simulating) proposed solutions in order to determine potential improvements. • Performing customer specific requests regarding simulation and results evaluation. • Contact with customer, presentation of work done on the project and future steps as well as performing training onsite for AVL AWS EXCITE PU software. • Development and verification of new analysis methods which are applied as AVL standard analysis. • Evaluation of component strength (high cycle fatigue) based on dynamic excitation using fatigue tools. • Simulation model review and preparation • Modal analysis evaluation of local and global engine eigenmodes (free-free and constrained) and its possible correlation with main engine order frequencies. • Forced response analysis. • FSI and acoustic analysis using Nastran/Actran • MBS simulation using AWS EXCITE PU software and results evaluation according to criteria for- Low frequent vibrations at engine mounts and auxiliary units- Evaluation of bearings (hydrodynamic pressure, asperity contact pressure, wear, thermal load, friction…)- High frequent vibrations, evaluating structure borne noise. • Analysis of transmissions and hybrid systems with regard to high frequent gear whine and rattle assessment. • Topology optimization of components based on MBS simulation results • Onsite work
