Drop Test Analysis of a Lamy Pencil
Dr.-Ing Matthias Hörmann, Steffen Schiele - CADFEM GmbH
Reinhard Probol - LAMY GmbH
Consumer products like cell phones, personal digital assistants, dish washers or cookers, to name just a view of them, are often exposed to drop during transportation to the customer and during usage in life time. Pre-damage, failure or malfunction due to drop is typically not acceptable and will lead to refusal through the costumer in addition with a correspondingly amount of financial and prestige loss. The present work deals with the ...
Dynamic Simulation of Mechatronic Systems
R.Cresnik, A.Rieser, H. Schluder - Virtual Vehicle
A growing number of safety systems are implemented in modern vehicles. Thereby vehicles become more complex and in succession the quantity of potential error causes is increasing. Numerical simulation and prototype tests are used to investigate vehicle behaviour and prevent aberrations at an early stage. However, prototype tests on full vehicle level are not feasible in early development stages. Numerical simulation is an effective tool ...

This work demonstrates a first approach of using virtually obtained material properties as input for forming simulations. The necessary parameters to apply a Barlat-Lian89 yield surface are computed in the so called “Virtual Lab”, which performs FE-simulations on previously cold rolled volume elements to predict the distribution of grains. The resultant stress-strain-curves serve as input parameter for a deep drawing simulation. For ...
From 6 months to 6 weeks "Multi Disciplinary Optimisation MDO"
Dr Tayeb Zeguer - Jaguar Landrover
The traditional new-vehicle design cycle is very time consuming due to the sequential approach used. The need to reduce time to market for new vehicles as well as the increased affordability of high- performance computing, which can process hundreds of simulations concurrently, has led to the increased adoption of MDO processes. The goal of an MDO is to provide a more consistent, formalized process for complex system design than that found ...
