Knowledge Preservation Management

The Knowledge Preservation Management (KPM) system allows for the capture, management, and Web-based access of manufacturing operations information. KPM also captures retirees' knowledge via transcript-enabled video-taped interviews, and with video data-mining advanced search capabilities. Access to this information is available directly to the operator on the factory floor or in an office, providing a complete, on-demand knowledge management and training capability.

Development of Automated Structural Health Monitoring for Composite Overwrapped Pressure Vessels

Virtually all NASA spacecraft use composite overwrapped pressure vessels (COPVs) to reduce the weight disadvantage of metal pressure vessels. However, these composite structures are more susceptible to damage than metal PVs, are difficult to inspect, have large burst pressure variability, and are susceptible to stress rupture when maintained at pressure. Over the past few years, NASA's Johnson Space Center (JSC) White Sands Test Facility (WSTF) has developed novel analysis methods that show promise for assessing the structural health of composite overwrapped pressure vessels. These methods and industry standard methods have been integrated into specialized software for automated analysis, thus significantly increasing throughput to the point where real-time assessments of structural health may be determined. Adaptive analysis methods have also been developed to provide modal analyses at specified points in a structure's life, including loading, unloading, and dwells. Together, these enhancements increase the utility and ease of use for acoustic emission testing.

Key Considerations for Powertrain HIL Test

Safety, availability, and cost considerations can make performing thorough tests of embedded control devices using the complete system impractical. Hardware-in-the-loop (HIL) simulation is a real-time test technique used to test these devices more efficiently. During HIL test, the physical system that interfaces to an embedded control device is simulated on real-time hardware, and the outputs of the simulator mimic the actual output of the physical system. The embedded controller “thinks” it is in a real system. HIL simulation meticulously tests embedded control devices in a virtual environment before proceeding to real-world tests of the complete system. This application note covers recommended best practices for powertrain HIL testing.

Sound-Off: How to Model Electric Bus Implementation

To reduce costs and eliminate air pollution, many cities are exploring the benefits of electric buses. Before electrified fleets take the road, however, officials will require a test run. The National Research Council of Canada (NRC) used a modeling approach.

A Modern Electric Bus Fleet: Improving Public Transit with System-Level Modeling

As cities across the world continue to increase in both population and density, public transportation plays a critical role in creating liveable cities. The current adoption of electrified transportation, however, presents a wide array of new challenges that must be carefully considered before these systems are implemented.

Product of the Month: October 2017

ANSYS, Canonsburg, PA, introduced ANSYS® Discovery Live™ simulation software that allows engineers to immediately examine the impact of their design changes. Users can pose what-if questions upfront in the design process to rapidly explore thousands of design options and receive immediate feedback. The software supports fluids, structural, and thermal simulation applications, enabling engineers to experiment with design ideas and see instant feedback. Users can run an analysis-first approach as they design, allowing them to iterate with a 3D model, and interactively explore the impact of simple and complex changes. The environment provides users with instant simulation results, tightly coupled with direct geometry modeling. The simulation technology is based on the parallel nature of NVIDIA graphics processing units (GPUs).

MSET Industrial Early Warning System

System breakdowns in modern industrial environments can result in millions of dollars in lost time and productivity, and even the loss of life and property. In the utilities industry — where the continuous operation of coolant pumps is essential — the breakdown of a single pump can result in a loss of as much as $10 million in downtime.

Robust Mesh Update Method for Grid Motion Problems

Over the past several decades, one class of problems in computational fluid dynamics (CFD) that has undergone substantial development involves movement of the fluid domain boundary. The problem class exists when the fluid domain boundary is either explicitly time-dependent, or is known a priori and determined as part of a flow solution in a coupled fashion. Free-surface fluid-structure interaction and forced-motion flows are typical of problems in this class. More specifically, as a boundary moves, a CFD mesh simulating the fluid dynamics can experience mesh cell distortion to the point of cell collapse, thereby rendering the CFD mesh meaningless.
