Structure
A mechanical engineering (ME) team joined the project in February, and worked on optimizing the design of the mechanical structure we made last semester. The original design of the structure needed to be modified in order to adjust to the change in the piezoelectric scanner that would be used.Â
The team had originally planned to add springs that would help keep the two pieces together, but after discussions with the mechanical engineering team, we concluded that the use of elastic bands to secure the top to the bottom of the structure and provide a layer of vibrational isolation, and uses two anchor points per elastic that are larger.Â
Due to the 3D printed model being so lightweight, the bottom piece was attached to a concrete block to prevent unwanted movement and limit vibration. Further work on this structure would involve vibration analysis which can be achieved with the help of accelerometers placed around the device.Â
