Reducing energy consumption used for stress relieving materials when using vibrating technology
The focus of this project is on stress relieving materials by exposing components and parts to vibrations (VSR) instead of heat treatment (TSR). We will research and document:
- Savings in energy consumption when using VSR instead of TSR
- Properties of materials atter stress relieving with VSR and TSR respectively
We will document the savings in energy consumption when using VSR instead of TSR. The documentation will be in the form of a white paper. Nowadays, it is mainly electricity used for the TSR and therefore it will the primary source of energy consumption related to stress relieving. We expect to see a relatively huge and measureable reduction. As a technology, the VSR is an important aspect of reducing the energy consumption with a significant amount without changing consumption or storing energy.
That means that the target of changing up to 50 % of energy consumption in industries from fossil sources to renewable sources in 2050 will be within rearch. We expect the industry to adopt the VSR-technology and implement it in a larger scale. This means that the project has assisted the industry in reducing energy consumption and using energy in an efficient way and thereby maximizing competitiveness.
It is investigated how the manufacturing industry can apply an alternative to heat treatment to control residual stress in metals, as this affect the productivity and the energy consumption in the metal industry. It is suggested to use vibrations to release the residual stress as this may be faster and more energy efficient than thermal methods. The technique, Vibratory Stress Relief (VSR), is tested on 13 different types of components to measure the energy consumption for comparison with traditional Thermal Stress Relief (TSR). By replacing TSR with VSR, energy savings in the range from 72 % to 100 % are obtained in the test cases. The material parameters of selected components are analysed to compare the result of both thermal and vibratory stress relief.
