Development Concept for Timber Truck
(2010) MMK920 20092Innovation
- Abstract
- The project “ETT-Modular system for timber transport” investigates the possibilities of making logging shipments more effective, decrease their fuel consumption and road wear without compromising traffic safety. As part of this project a timber vehi-cle, the ETT-vehicle, that pulls four piles of timber, is 30 metres long, and has a gross combination weight of 90 tons, is tested on a distance between Överkalix and Piteå in the north of Sweden. By adding one more pile to each vehicle and also increasing the load in each pile, two logging shipments will be able to replace three. Fuel consump-tion measurements on the ETT-vehicle indicate a 20% fuel reduction per ton-km compared to a conventional timber truck with a maximum weight of 60 tons.

Fuel consump-tion measurements on the ETT-vehicle indicate a 20% fuel reduction per ton-km compared to a conventional timber truck with a maximum weight of 60 tons.
The purpose of this thesis is to investigate the strengths and weaknesses with this particular vehicle and present a development concept of a vehicle more optimised for the application. Focus is the fuel consumption, the safety and the identity of the vehi-cle. The development process used is adapted from the Generic Development Process presented by Ulrich and Eppinger and the main source of information is interviews with project members and experts. The interviewees are asked questions about the existing vehicle and wishes and ideas for a future ETT-vehicle. From the interviews statements are translated into customer needs with some of the most important needs being reduced aerodynamic drag and rolling resistance, increased loading capacity, improved visibility of vehicle and a wish that the vehicle is seen as a transport solu-tion, rather than a truck with a number of trailers. From these needs a concept genera-tion is performed where solutions to all the needs are generated. These solutions are then evaluated and tested in simulations, illustrations and discussions, from which a number are chosen for the development concept. The chosen solutions are combined into one complete vehicle development concept. Vehicle simulations in GSP – Global Simulation Platform, are used for testing and evaluation of product concepts and the determination of product specifications for the development concept.
The development concept indicates a possible fuel reduction of about 10% compared to the existing ETT-vehicle. Focus in the development concept regarding the fuel consumption is improved aerodynamics, increased loading capacity, an optimised driveline and reduced rolling resistance. Further the safety is improved and the iden-tity of the vehicle made stronger.
Further research can be conducted in order to firmly establish the results of this de-velopment concept and the estimated effects of some solutions. However, the results show high potentials in improving the fuel consumption for timber trucks. (Less)
