Creating Interactive Techniques and Automated Workplaces

Using ANSYS EKM allows to create automated workplaces and interactive techniques on the basis of ANSYS software and other products. An interactive technique is a web-application which works with one or several parametric models. Such environment allows to customize the software interface according to user’s demands.

Inter-bay current leads

 
CADFEM CIS has an experience in creating interactive techniques based on using EKM software. The relevant project was prepared for LLC «Scentific Production Center «Marine Electrotechnical Systems». The profile of the company includes design of marine inter-bay current leads.

The shape of inter-bay current leads may vary significantly, and they need to be tested on fire resistance, mechanical strength and electromagnetic compatibility. There are special criteria for evaluating results in each type of analysis. To improve productivity, it is necessary to minimize and streamline the design cycle. Moreover, the production must comply with high quality standards.

To meet all these demands, three interactive techniques have been developed basing on ANSYS DesignModeler geometry preprocessor and JScript. Fire resistance and mechanical strength were simulated in ANSYS Mechanical, and electromagnetic compatibility was analyzed in ANSYS HFSS. All simulations were performed automatically on the remote high performance server using ANSYS Remote Solve Manager.

CAD models of inter-bay current leads

 
Simulation models used in interactive techniques have been prepared by the engineers of CADFEM CIS. All settings were chosen so that the models produced the most accurate results with any acceptable input data. For example, FEA mesh parameters were chosen based on geometry. Besides parameterization, in interactive technique, problem settings were enhanced in such a way as to decrease calculation time without reducing results accuracy. For structural and thermal analysis, steady-state approach was used. The engineers developed methods allowing to evaluate the construction performance capability using linear material properties. The experts were initially planning to use transient electromagnetic compatibility analysis, however, they managed to solve the problem using harmonic signal analysis in a narrow frequency range.

Web-interface of the interactive technique is in Russian language, and it is highly simplified. It is possible to visually control geometry of the model. If a construction fails the test, the user needs to change the previous input data. When the simulation is complete, the software automatically generates reports and visualizes results as stress and temperature fields for structural and thermal analysis. From electromagnetic compatibility analysis, the user can visualize the model with highlighted current leads of worst parameters. All simulation results are saved in the EKM database, which allows to perform detailed analysis, if it is necessary.

The project performed for LLC «Scentific Production Center «Marine Electrotechnical Systems» shows interactive technique usability for inexperienced engineer having no skills in ANSYS software and simulation analysis. The engineer can quickly and efficiently design new products, while the model will be set optimally without a risk of being improperly modified.
