This presentation was made at the NAFEMS European Conference on Simulation-Based Optimisation held on the 15th of October in London.

Optimisation has become a key ingredient in many engineering disciplines and has experienced rapid growth in recent years due to innovations in optimisation algorithms and techniques, coupled with developments in computer hardware and software capabilities. The growing popularity of optimisation in engineering applications is driven by ever-increasing competition pressure, where optimised products and processes can offer improved performance and cost-effectiveness which would not be possible using traditional design approaches. However, there are still many hurdles to be overcome before optimisation is used routinely for engineering applications.

The NAFEMS European Conference on Simulation-Based Optimisation brings together practitioners and academics from all relevant disciplines to share their knowledge and experience, and discuss problems and challenges, in order to facilitate further improvements in optimisation techniques.

Resource Abstract

In recent years, the automotive industry has seen a significant increase in in-vehicle comfort demanded by customers. One of the most important parameters affecting vehicle comfort is in-vehicle vibration. The main source of in-vehicle vibration is the engine. Due to increased engine power progressively, the selection of mounts becomes dramatically more important to dampen the transmission of the vibration arising from the engine through the vehicle. Mount selection, which affects natural frequencies of the system, is also an essential parameter for determining vehicle idle speed.



In order to reduce the vehicle idle speed, an optimization study has been performed for powertrain modal alignment. At the end of the study, by all outputs the most proper engine mount stiffness values has been chosen.
