This past week, we had a chance to display a few of our shake tables at the 9th US National & 10th Canadian Conference on Earthquake Engineering in Toronto. It was a great opportunity to speak with many instructors and researchers who are using the shake table as part of their teaching and projects.
For the first time EVER outside of Quanser's headquarters, we had the Hexapod, our 6 DOF motion platform on display. Many attendees stopped as they passed, mesmerized as they watched the Hexapod play out the Northridge Earthquake of 1994 in x, y, and z directions. We also added some random yaw, pitch, and roll signals to give a more realistic effect.
Also on display were the Shake Table II and the Shake Table I-40. These systems are much more portable and great for teaching structural dynamics. You can see a few videos of the shake tables below. Enjoy!

I am Golam Yasin Khan an earthquake Resistance Technology developer. I want to ask Quanswer engineer team by the shake table experiment what you guys are teaching the new generation students. Sake table experiment will not help at all the earthquake resistance, what I experience from the shake table it’s maximize the earthquake thrust effect on the stricture, instate of minimize, it should maximize on the foundation. This is the only way to resist earthquake. There is some technology available which resist the earthquake with limited life time, expensive and difficult to install. This is the reason up to this time; only 10,000 installations have been equipped with this technology which is very small number in the world arena. I have invented a technology which will be the future earthquake resistance technology. It’s true that I did not go for the large scale due to the privacy reason and lake of facilities, but you will find the concept of this technology on my proto type in action. Please see the link bellow.

As is healthy in any field of research, we are happy to see and encourage different opinions. The mass damping mechanism proposed by Quanser is a process that is used in universities for research and teaching and was approved under the University Consortium for Instructional Shake Tables program supported by NSF. Since then, having been selected as part of that program with our Shake Table II, the solution is available to other universities. We are also exploring base level vibration isolation mechanisms for research and student training. We would be interested to see what other professors and researchers feel about your opinion on this point and hope it initiates a constructive discussion.
