A simulation apparatus is provided comprising a fixed main body; a carriage associated with the main body for movement relative to the main body; a first device coupled to the fixed main body for engaging a workpiece; a second device coupled to the carriage for movement with the carriage and for engaging the workpiece; at least one motor apparatus coupled to the fixed main body and the carriage for effecting movement of the carriage and the second device relative to the main body such that a tensile load is applied to the workpiece; sensor apparatus comprising at least one force sensor for sensing the tensile load applied to the workpiece during the movement of the second device; and a drive controller. The controller is coupled to the motor apparatus for controlling the operation of the motor apparatus in accordance with predefined carriage positions corresponding to discrete time intervals and in response to feedback from the sensor apparatus comprising the at least one force sensor so as to enhance the control of the position of the carriage as a function of time.

Simulation apparatus

A method for inducing strain on a workpiece includes the step of providing a testing apparatus having a first set of teeth and a second set of teeth. The workpiece is placed adjacent to the first or second set of teeth. The second set of teeth is disposed on a movable carriage which linearly reciprocates thereby allowing the first and the second sets of teeth to engage and disengage each other. A commanded position by time is provided to the carriage while the actual position by time of the carriage is measured. The first set of teeth are in communication with at least one load cell such that when the first set of teeth engage the second set of teeth, the load applied by the carriage is measured. The actual position by time data and the load data are manipulated to produce vast information pertaining to the workpiece.

Method and apparatus for the variable speed ring rolling simulation of substrates

A simulation press is provided comprising a fixed main body; a carriage associated with the main body for movement relative to the main body; a first plate coupled to the fixed main body and being adapted to engage a workpiece; and a second plate coupled to the carriage for movement with the carriage. The second plate is also adapted to engage the workpiece. One or more motor apparatus are coupled to the fixed main body and the carriage for effecting movement of the carriage relative to the main body. A drive controller is coupled to the motor apparatus for controlling the operation of the motor apparatus in response to feedback from one or more feedback sensors so as to cause the second plate to move relative to the first plate such that the first and second plates engage at least one point site on the workpiece so as to simulate compression loading of a point site on a workpiece in a nip type process.
