| Abstract |
This work describes the research, designs, and findings in the senior design project this team has worked on. Over the course of this past school year, this team was formed to complete impact survivability testing on an accelerometer for BTech Acoustics. The accelerometers being tested are used in environments in which they could be subject to high amounts of shock. The sensors must be able to continue to function properly after being exposed to those high amounts of shock, so this team’s goal is to test and observe at what point the sensors no longer work so improvements can be made on the design. The main objective for this semester was to design an experimental set up for the testing and be ready for testing next semester when the accelerometers are available. Using a Hopkinson bar, the accelerometers will be struck with increasing force until a signal is no longer received from the device. Due to closures on campus, the team was not able to complete impact testing. The project was shifted to research that could be completed remotely. Also, in this report will be the details of simulations run by this team of what would be seen with the device being tested in a conical shock tube. The shock tube was designed by the team and the simulations were completed using Comsol |
