Purpose and goal
The objective was to test strength, stiffness, production cycle time and cost for the rear end of a Volvo city bus using 3Dlitetechnology.The result is that the technology functions and that the the production cycle time is about 3 min for the core filling.The design has been compared with a carbon fiber structure and is as strong and stiff as the carbon fiber structure but to much lower cost. The rear end will be heavier but light enough for this application. The final product will be built in the late fall of 2014.
Results and expected effects
The result is that the technology functions and that the the production cycle time is about 3 min for the core filling.The design has been compared with a carbon fiber structure and is as strong and stiff as the carbon fiber structure but to much lower cost. The rear end will be heavier but light enough for this application. The final product will be built in the late fall of 2014. The implementation will be done ASP due to the world market demand for light weight electric and hybrid buses
Approach and implementation
The project was done in 3 steps. 1. Design of the rear end 2. Test of core filling technology 3. Building of the rear end The result is that the technology functions and that the the production cycle time is about 3 min for the core filling.The design has been compared with a carbon fiber structure and is as strong and stiff as the carbon fiber structure but to much lower cost. The rear end will be heavier but light enough for this application. The final product will be built in the late fall of 2014. All partners likes the project design.
