Purpose and goal

Immediate outcomes (project): - Extended life for Staccatoventilen from 300 million to 500 million operating cycles - Reduced variability of life - As the overall direct impact of these results is made possible use against tougher requirements and new applications The three goals of the application are met.

Results and expected effects

We have in the project identified and verified all life limiting factors. We have, through research performer Swerea Kimab received solutions that have increased life expectancy of at least 500 million switch operations which was one of the project goal. We also stabilized the characteristics of life in a desirable manner. Through the project, we have created the confidence of one of our clients. We have the project built up our internal knowledge of the areas that limit our technology´s lifespan and thus improved our skills in further development

Approach and implementation

The original design has been incorporated into the Swerea Kimabs simulation models. The materials analyzed. Test results from field tests have been analyzed. Wrecked the detail has been analyzed by Swerea Kimab. Based on the analysis, since the proposed solution has been developed to meeting project objectives. These solutions have been converted into construction drawings in consultation with manufacturing facilities of details. Subsequently, the new solution has been tested and compared with the previous designs.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
