NX Motion Control is a new product from Siemens PLM Software, a leading global provider of product lifecycle management (PLM) software and services. It enables cosimulation of controller designs based on Simulink that have multibody dynamics models in NX. Using this capability, mechanical engineers and designers can collaborate more effectively with their counterparts developing controller designs to find and fix integration issues and to optimize product performance. With NX, users leverage a common environment for performing design, motion simulation, and advanced structural analysis, enabling data and model sharing for greater team productivity.
In a typical workflow, a mechanical engineer or designer models the mechanical plant in NX Motion while a controls engineer builds a model of the controller in Simulink. Control signals provide force, torque, or velocity inputs, and NX Motion outputs are fed back to the controller. You then specify plant input functions and sensor-based plant outputs within the NX environment. To integrate the two models together, you can drag and drop a plant representation into a Simulink block diagram. Once a simulation is complete, you can review the results using powerful postprocessing and animation capabilities within NX.
