Elastic elements for generating a pretension force

In mechatronic machines with a high positioning accuracy (i.e. submicron positioning), it is often necessary to have a stiff connection between the machine components. It can be deduced from the mechatronic model of a machine of this type that a certain connection between components has to be stiff (but not necessarily strong). A defined pretension force between the components is needed to optimise connections for (contact) stiffness. The design principle of a harmonica bush offers an elegant solution.

Order of frictions and stiffnesses…

For lumped systems consisting of different frictions and stiffnesses, there has been confusion in literature about hysteresis curves and virtual play for many decades.
