1. Integrative Design Process Using Mechatronic AnalysisRazvan PanaitescuDesigning an electro-mechanical system is the work of art of many engineers. Every new design comes with a challenge and new, tougher, constraints: more precise, faster, adaptable to process changes, more robust. We use past experience and try to enhance the basic building blocks in order to build a better machine. How fast can I be in position with this rotary axis? How can I get the planned accuracy of this milling machine and improve the quality of the surface finish? Why do I have this noise during the operation? – to list just a sample of many questions arising during the design/production process. |

2. Mechatronics Design with NX Motion and MatlabRazvan Panaitescu and Mathias OppeltSiemens’ NX Motion Simulation, which is part of NX Suite, enables designers to connect mechanical simulation with control simulations and to allow designers to co-simulate in both the NX environment and Matlab, giving designers fast and realistic insight into the dynamic machine and control behavior of a system modeled in almost any 3D CAD software. With the release of NX6, the user has the ability to integrate mechanical simulations of all controls and drives with any Matlab/Simulink control structure in a Co-Simulation environment. This unified simulation environment allows the designer to dynamically analyze the complete machine, while predicting performance, resulting in faster, more complete prototypes with shorter development schedules. A good Mechatronic simulation reveals design issues early in the development process, allowing the designer to explore multiple design alternatives and virtual prototype iterations, bringing the product to market faster with less development cost, higher precision, and increased productivity. The purpose of this paper is to describe how NX Motion conducts controller-integrated simulations as part of a complete Mechatronic machine analysis. |

3. Design Analysis and Optimization using NX Motion 7.5 and MatlabRazvan Panaitescu and Johannes
Popp Mechatronics Consulting offers an extensive engineering service to evaluate conceptual machine designs and improve existing machines. In order to find the ideal parameter settings and optimize the design, a digital prototype is developed that behaves identically to the real physical system. By considering all technical domains, such as mechanics, electronics, and control architecture, it is ensured that reliable results can be derived from examining the digital prototype. Based on measurements of the dynamics, the control configuration is optimized and the mechanism is evaluated and if necessary changed. In this video it is demonstrated how NX 7.5 and the co-simulation feature of Matlab/Simulink can be utilized for developing a holistic digital prototype. Additionally, we outline, how the performance of a machine can be maximized using a Mechatronics analysis approach. |
