Active Vibration Isolation Challenge
The goal of the Student Challenge is to attach a focusable laser to the isolator to be pointed at a fixed target. Feedback for stabilization can use one or more MPU 9250 triple axis accelerometers and knife edge displacement sensors (if needed). A first test will be the ability of the isolator to maintain the laser on target at a distance of 6m. For the second test, a motor spinning an unbalanced mass will be attached at an edge on the underside of the breadboard. The speed of the motor will then be increased while the laser is projected onto a circular target, again at a lever arm of 6m. The gage of performance will be the motor speed at which the pointer cannot stabilize the position of the spot to stay within the circle. Rotation of the unbalanced mass will produce an angular motion of the breadboard (without the additional mass of the isolation mechanism) that will be less than ±0.5 degrees.
The isolation mechanism will mount directly onto breadboard plates (Newport 12x12x1/4-20). Four coil springs will be attached to the underside of the bread board plate forming compliant legs. This breadboard plate will be placed on the table in the work room where the competition will take place and the active isolation mechanism must be assembled onto the board. Only mechblocks, voice coil actuators, voltage to current amplifiers, knife edge sensors and MPU 9250 triple axis accelerometers can be used for assembly of the isolation stage. A complete spreadsheet containing detailed information plus component STEP files will be available to all teams. A National Instruments myRIO will be supplied (if necessary) for control and software to read this device over the SPI bus will be available.
More details about the Challenge will follow soon. In the meantime, REGISTER your team today!
Sponsorship Opportunities: Getting teams engaged early will also allow for the organizing committee and ASPE to have more time to obtain the resources required. This may include sponsorships for hardware, training, perhaps support to lower travel expenses. Selected funding from sponsors will go to prizes, the purchase of recyclable hardware (i.e. reusable for subsequent events), and student financial support. Student financial support will be necessary to alleviate the burden on individual professors to fund student teams to the challenge and will be an opportunity for the sponsors to establish closer relationships with the University, professors and students. The sponsors can also request one or more of these specific areas whereby their support is allocated.
