Simulation in Industrial Equipment and Rotating Machinery
To achieve targets, developers look at improving all aspects of machine performance.
Increase Process Stability and Mitigate System-Level Errors with Simulation
Industrial equipment and rotating machinery are designed by the need to deliver stronger performance with improved efficiency, safety, and durability to perform the necessary tasks.
However, as global integration pushes manufactures and heavy industries alike, the need to optimize processes and mitigate product failures has become more essential than ever.
The Impact of Simulation on the Future of Design Manufacturing
Designers and Analysts look at every aspect of the machines to find areas to improve for enhanced performance.
Having to take in many factors such as emissions of NOx, SOx, hydrocarbons, and soot, design engineers face several challenges in making energy efficient machinery while addressing emissions guidelines and standards.
Ansys Multiphysics capabilities offer the ability to factor in various real-world interactions and stresses to ensure accurate predictability in machine design.

Generator Vibration Testing Services
Common Mechanical Testing services requested by clients across the United States and Canada.
Bump Test
An instrumented modal hammer is used to perform a driving point measurement at the end winding series caps and phase connections.
Each location is excited and measured in three directions. Multiple impacts are applied in each degree of freedom with special care given to data quality and coherence.
Frequency response functions (FRFs) are calculated to provide timely preliminary results to the engineers responsible for system under repair.
Global Modal Test
An instrumented modal hammer is used to excite the structure in three directions. From here, the response is measured in multiple planes and circumferential locations for optimal spatial resolution.
Frequency response functions (FRFs) are calculated and processed in Siemens LMS to extract the natural frequencies and mode shapes.
Core Modal Test
An instrumented modal sledgehammer is used to excite the structure in multiple directions.
The response is measured in multiple planes and circumferential locations for optimal spatial resolution.
Frequency response functions (FRFs) are calculated and processed in Siemens LMS to extract the natural frequencies and mode shapes.
A mechanical engineer “taps” the core stage with a calibrated impulse hammer, sending vibrations along the structure. The collected data will validate or invalidate engineering models predicting how the structure will behave both in test and launch phases.
