Often in the classroom realism is difficult to obtain when explaining and experimenting with real world systems, processes, and naturally occurring forces.  Simulation has come a long way in providing our students with the realism that is required when learning through software simulations such as Finite Element Analysis and Digital Prototyping but physical attributes of engineered systems are sometimes more difficult to ascertain.  NI miniSystems are an excellent way to fill the gap between software simulation and real world systems by providing small scale replications of systems that exist in everyday life.  Let’s have a look at the NI myQuake.

The myQuake miniSystem for National Instruments

The NI myQuake is a motion control system used to simulate the effects of earthquakes on various structural systems.  The systems that are subjected to the simulated earthquakes can be student designed systems or pre-built structures.  The forces of the earthquakes are measured using two accelerometer inputs.  The movement on the structure and its reaction to the simulation are measured through the NI myDAQ with the accompanying LabVIEW program.

Here at Studica we are using the myQuake with a fischertechnik Super Cranes kit. We have constructed one of the Cranes and hypothesized on its weakest structural points.  Using LabVIEW we were then able to determine how accurate out hypothesis was.

Using Cranes to Test Structures

The fischertechnik Crane was a fairly complex target for this test and the simulation can be run on many other models or student projects.  Whether the aim is to teach Programming and the use of Accelerometer Inputs and Motion Control outputs with LabVIEW, or to teach structural integrity and building principles then the myQuake is up to the task.

Student designed projects, simulations, and programs are also an excellent use for this NI miniSystem. From simple teacher lead projects to larger scale project based learning environments the NI myDAQ with myQuake offers an interesting way to teach hands on design, prototyping, data acquisition, data analysis, resonant frequencies, simulation and sensor measurement.  If you would like to see this miniSystem in action please do no hesitate to contact us at Studica.
