Quality assurance of innovative product for dynamic and adaptable truck balancing

Important results from the project

The project partially met the goals set at start. The goal of completely ensuring how the product influences a truck´s balancing was too high. On the other hand, a very good basis for further investigation was laid, and most important lessons were emerged; which variables need further verification and what processes need to be refined. The project as a whole was successful and provided a good foundation for further development and testing of the product.

Expected long term effects

The results in the tests were ambiguous and gave no perfectly clear indication of how the product affects the balancing of the truck. The product did show signs of adaptive balancing while the truck was on the road, but not with scientific certainty. More variables need to be checked and controlled in the future to ensure the right conditions.

Approach and implementation

The tests were carried out on a hired truck fitted with accelerometers to measure imbalances in all directions of the wheels. The driving route was located on the E6 south of Göteborg and the truck ran the same route with different effects on the wheel´s balancing. Half of the time was used to ensure that the sensors were properly mounted and half of the time to test the product. Afterwards it is clear that more time had to be put on the test of the product, with better control of variables, but this became a resource issue when planning.
