Analisys of dynamic load and a dynamic coefficient at time-effect strength

Abstract

The article presents the analysis which tends towards the load appointment caused by impacts. The mass falling from a particular height is the most frequent case causing the dynamic load. In order to illustrate the dynamic force (reaction) it is needed to appoint the character of the impact and find the restitution factor. Duration of the dynamic impulse allows us to discover the value of the dynamic force (reaction) as well as a dynamic coefficient. Calculated protection coefficients for an assumed model of a bending beam are higher than the ones used during designing.
