Simulations more effective than hardware tests

Published: 2 June 2016

A newly developed simulation-driven methodology streamlines the product development process for mechanical systems. More concepts can be evaluated and selected earlier in the process. This is presented in a doctoral thesis by Jonas Pavasson at Luleå University of Technology.

Using a simulation-driven methodology can better predict the reliability of mechanical systems. Today the durability of a system is measured in the number of hours the transmission in a vehicle meets the requirements, determined by hardware testing on a small number of vehicles.

– To instead predict the reliability of mechanical systems by using simulations provide a better measure of how multiple systems can cope with the demands because the analysis is done on a statistically significant basis, says Jonas Pavasson, PhD in Computer Aided Design at Luleå University of Technology.

Jonas Pavasson’s simulation-driven methodology thus makes it possible to predict the reliability of transmission for wheel loaders in the earlier stages of the product development process. This leads to savings in time and resources.

– Hardware testing of mechanical systems is a time-consuming work to implement and analyse, simulations allow time and resources to be streamlined and re-assigned to other tasks. Hardware test then do not need to be implemented and the systems are optimized for delivery to the customer.

Before the results from Jonas Pavasson’s research can be implemented, models in simulation-driven methodology need to be validated.

The thesis has been conducted within the framework of the VINNEXC Faste Laboratory with Volvo CE as industrial partner and VINNOVA as financier.
