Abstract
This paper presents a new method for calculating maximal collision forces in kinematic chains based on their impulses. Its main advantage is its simplicity as it is based on algebraic equations. Collisions between the feed, hammer and rotor in a hammer crusher are used as a case study to show the implementation of the proposed method. The obtained results are then compared with a reference time-domain model. The proposed method can be used by mechanical engineers in early design phases to estimate loads acting on parts during collisions as well as to search for more optimal geometrical parameters.
