Today, bridge structures are tested with unique constraints. Vehicle loads and extreme conditions give researchers a better understanding of the impact these structures can withstand. However, bridges are not being designed for both of these conditions at the same time.

 

Researchers at the University of Nevada, Reno are using graphical system design to test bridge sections and the extreme conditions they may endure. To better understand the behavior of these immense structures during an earthquake and the combined load of a vehicle, researchers wanted to accurately test how the vehicles suspension system interacts with the movement of a bridge. They achieved this by building bridge sections and simulating earthquakes with large hydraulic shakers.

 

NI data acquisition hardware and the NI LabVIEW Real-Time Module helped the researchers easily program a system that could monitor critical components of their simulation such as strain, force and displacement. The ability to collect and process accurate data all with one platform made the test system a huge success. The entire system design gives researchers the capabilities to better understand the behaviors and movements of the structures we drive across every day.

Two important elements in a sustainable urban infrastructure are public transportation and green structures. Not only are they important, but they also help create sustainable living conditions for a

community. That’s why engineers at National University of Singapore created the first working prototype of a zero-energy bus stop (node) that was also user friendly for commuters.

 

Powering a zero-energy bus node that is self-sustainable requires electricity. The engineers needed to situate solar panels on the top of the bus node. To further the energy supply, they mounted the solar panels on a rotational base that causes the panels to adjust with the weather information received by a controller. Using the energy supply from the abundant sunlight created enough to power one entire bus node.

 

The next crucial element was creating a solar panel powered system. The engineers created a three-part system made up of sensors, actuators, and a controller. They used NI CompactRIO hardware and LabVIEW software to give the controller capabilities for obtaining up-to-date arrival times, current traffic conditions, and other navigation information for passengers right on-site.

The use of integrated NI hardware and software helped engineers create the first working prototype of a zero-energy bus node. This entire bus node is 100 percent self-sustainable in electricity consumption and Singapore now has a ready platform for energy control activities that will help create a more sustainable infrastructure in the future.
