ABSTRACT
The computer modelling technique most often used for the analysis of structures is that of finite element analysis. In this technique the geometry of a complex structure is defined by a series of elements, the shape of which is determined by the form of the structure. The system isolation should ensure that none of the thermal or mechanical forces produced in or by the device should be transmitted to other connected structures or to the user. Mechanical cams and linkages have been employed to provide the necessary controlled motion paths, with adjustment or reconfiguring only achievable during shutdown and often with difficulty. The extent to which such mechatronic systems can be applied depends upon the accelerations and forces to be controlled and the available slew rate of the driver. Applications where such parameters reach extremely high values, as in cigarette making machines, canware manufacture and chequebook printers will see traditional mechanical cams continuing in use.
