Team Vision for Problem Definition Phase

Our plans was to finalize a set of customer requirements with a basic set of ideas and engineering requirements to tackle them. Additionally, as a team we wanted to define our norms and values, set-up a schedule for the year, and to make a draft of our plan to solve project.

Project Summary

As a continuation of project P18310. Project P18310’s purpose was to build two vibrating mass systems to demonstrate the effectiveness of LORD’s TVA (Tuned Vibration Absorber) technology at trade shows and academic presentations. Project P19310’s goal is to take the existing unit and refine the design and software to create a more effective and portable solution.

History from P18310: A Tuned Vibration Absorber (TVA) is a device used within a system to reduce the severity of vibrations of a specific frequency in order to improve the robustness of the system. LORD is a company that sells TVA’s for industrial use, but is unable to demonstrate the technology at trade shows, as no equipment currently exists for this purpose. Ideally, a system could be created that allows for the direct comparison of the two vibration systems , while at the same time providing data to support the demonstration in a manner conducive to table top displays.

The key goals of this project are:

De-couple the two vibrating masses
Re-write existing QT code into MATLAB
Reduce packaging size and weight of system
Reduce footprint/Improve packaging

The key constraints for this project are:

MATLAB must be used for display software
Weight reduction
Maintain ruggedness, product needs to be rugged enough to survive multiple trade shows
Improve products ability to clearly and effectively show the benefits of the customer’s TVA
To be easy to assemble and disassemble.
Be portable and require only a standard outlet connection to operate.

By May 2019, it is desired to have a refined version of the original prototype to provide to LORD with all changes made to the engineering documents, bill of materials, and detailed working/ troubleshooting instructions to be documented and updated. Additionally, the existing software package will have been re-written in MATLAB.

Use Cases

Project Goals and Key Deliverables

Key Deliverables:

Working TVA display unit that shows minimal vibrations in the mitigated unit during operation, capable of running at the customer-desired frequency for the length of the trade show, and small/light enough to be easily transported and operated. Software package written in MATLAB capable of displaying the potential of the TVA product.

Project Goals:

To provide to the customer all the key deliverables detailed above. To meet as many other additional high-priority customer requirements as possible.
