Abstract:
At IMEKO - XV World Congress, the design of the first UK national torque calibration machine was described.
As part of the design of the machine frame, a structured finite element (FE) study was carried out to predict its behaviour. A series of models were created, with varying levels of idealisation. These were used to evaluate the linearity of response to load application, the deflection and stress states under differing load conditions, and dynamic response using both modal and post-dynamic analysis. The effect of using tubular columns in the upper structure in place of solid bars was also modelled.
The study provided confidence in the design of the machine frame and reduced the risk of post-manufacturing changes. It also contributed to the design of the software that controls the application of deadweight masses and the applied torque.
During commissioning of the machine, deflection and frequency measurements will be made to close the design loop and provide validity to the FE analysis.
