We’ve discussed the need to simulate a full system quite a bit in this blog over the years. The need is clear: as products become smarter and more complex, component or sub-system simulation alone isn’t sufficient. As automobiles become computers on wheels, as your mobile phone has more compute power than the desktops of only a few years ago, there are new ways for products to fail. In other words, systems safety and reliability analysis is more critical than ever. Continue reading
Read any industry publication today and the Internet of Things (IoT) is a hot topic.Talk about how products will be connected to each other and interact with users on different levels is everywhere. But is all of this really possible? Will we see this type of connectivity and interaction any time soon? Gartner, the technology research company, says that there will be 6.4 billion connected devices this year, and many of these will be in the industrial sector. What advantage does this connectivity bring — digital twins, predictive maintenance and predictive analytics. Continue reading
I knew it was just a matter of time before the technology took off. This week, Amazon founder and CEO Jeff Bezos announced that his online store is developing a drone-based delivery service.” The Amazon drones, called octopeters, are expected to deliver products to customers only a half-hour after they click the “buy” button.
This “science-fiction” approach to deliveries is still a few years away, but it’s no longer out of the range of possibilities. And won’t it be fun to watch a recently ordered item literally drop out of the sky?
The Amazon Drones
The Amazon drone is the size of a flat-screen monitor powered by electric motors. It follows GPS coordinates to drop items off at target locations. “The hard part here is putting in all the redundancy, all the reliability, all the systems you need to say, ‘Look, this thing can’t land on somebody’s head while they’re walking around their neighborhood,'” Bezos told CBS 60 Minutes.
And this is where ANSYS engineering simulation comes in. Today, product differentiation increasingly depends on embedded software, including complex control code and user-friendly human–machine interfaces — which in turn increases product complexity and risk. So the latest ANSYS capability optimizes embedded code. SCADE Suite offers the unique capability to graphically design, verify and automatically generate embedded software for smart product applications — like drones. Continue reading
High-speed train travel has been in the news recently due to the unfortunate accidents in France, Spain and Switzerland. Much has been discussed about the systems used in trains and how they work or don’t work in order to protect passengers as the travel at high rates of speed from one location to the other. Although, high speed rail travel is not prevalent in the United States, it is widely used as a regular form of transportation throughout the rest of the world, and despite the recent news items, it is very safe. There is always room for improvement though.
So, how do the systems used within the rail infrastructure ensure passenger safety? There are three issues that must be considered: speed, avoiding other trains on the track and making sure that the train travels as intended. Complex software systems in both the train control center and on-board the train control these functions, if the train is completely automated. And these systems work very well if properly implemented. For example, train control systems control the speed of the train and its “movement authority”. Just like an autopilot on a plane, the overspeed protection will not allow the train operator to exceed the designated speed for that portion of the track. Continue reading
