Dynamic Mechanical Analysis Piezoelectric Design

This project is a continuation into the design and implementation of a Dynamic Mechanical Analysis (DMA) device that will be used to conduct high frequency testing on tire tread compounds. The design requirements necessary were to design a device that will produce a target frequency of 10 kHz with a 0.05% strain, while being at room temperature. The 3-D model developed by the previous year’s students was improved upon and new parts were designed as well. The assemblies (most importantly the connector piece) were 3-D modeled using Creo Parametric and analyzed with COMSOL Multiphysics. A new design involving flexures was also designed to be used in the third year of the project to help increase the overall frequency of the assembly while adding support to keep the assembly in place. Different designs were examined to determine the best design that met all of the design requirements. After the best design was chosen, communication with both local and international companies was done to determine the best method for manufacturing. Communication with companies that could give quotes for glue used to prevent the rubber from shearing off the metal surfaces. The part was then ordered and delivered to the university. The part was then assembled to ensure the parts were manufactured properly and will be tested in the future
