Vidareutveckling av ett dämpat slagstäd till en slagutmattningsutrustning

Sammanfattning: Impact fatigue is an area which very little research has been carried out in. Of interest from companies in the rock drilling industry, Karlstads University has resumed research in the field of impact fatigue. During its experiments, Karlstads University wants to preform experiments with both a solid anvil and a damped anvil. As the damped anvil is a new product this work has followed a typical product development process. In order to be able to evaluate the different solutions, an elimination matrix has been used in connection whit some estimated calculations. The final concept uses a hydraulic cylinder in conjunction with a piston accumulator. As the concept is hydropneumatics and the hydraulic cylinder will need to be modified, there is a potential risk of leakage. The dampening properties of the final concept are enough to be able to perform the work that the client demands.
