Mechanical force-displacement procession test modules are test rig and test system components for 100% mechanical inspection of mounted assemblies and products as well as functionality tests. The test modules are based on controlled drives for introducing defined forces and paths into the test object. For functional testing, the test item is subjected to mechanical input variables by the test module, and the resulting output variables are compared with a nominal value. In the functional test, therefore, not every single component is tested for function, but it is assumed that all individual functions are also correct if the overall result is correct. Typical tasks are the automated 100% control of screw threads and gears as well as friction torque measurements on adjusting elements and ball bearings. Typical products are mechanical products such as combustion engines and transmissions, electrical products such as electric motors and household appliances, electronic products such as automotive control devices and mobile phones or fluidic components such as pumps and valves. For a functioning test system, a workpiece holder for fixing the test object as well as a sequence control, an optional measurement data acquisition and evaluation as well as the user interface are required. Users are the internal tooling and equipment departments, the test systems as well as the special machine and system engineering for the automotive and automobile supply industry, manufacturers of electrical components, electrical and domestic appliances and other industries.
