One of the most common questions I hear the team getting asked at competition is how the design of a certain component was validated. As a senior design project, 3 peers and I are working to build a custom shock dynamometer to provide the team with a method of tuning and validating shock damper tunes for competition. Our goal is to build a fully functional shock dynamometer for a fraction of the cost of buying one off the shelf. The team must work with a strict budget and timeline; along with size, performance, and accuracy requirements. We plan to have a controls system built into the dynamometer allowing the user to easily change testing parameters such as the speed at which the the shock is compressed and expanded to more realistically replicate racing simulation. After doing some competitive benchmarking, we have decided to construct the dynamometer using a DC servomotor connected to a scotch yoke as a method of transmitting rotational energy into linear. Analysis in MATLAB helped determine the power and torque requirements the motor will need. I have completed a preliminary CAD model of the product using SolidWorks showing the current state of the dynamometer. I have also began selecting which sensors we will use to measure force, shock temperature, and displacement during testing. The design is scheduled to be completed by December 1st.
