Abstract

In the current practice, sensors such as the accelerometers and strain gages are attached to or embedded into structure to measure its response for structural health monitoring purposes. However, installation and maintenance costs of these sensors are high, and the process is time and cost consuming partially because the operation of the structure has to be interrupted to perform the maintenance. Acoustic sensor with its ability to capture sounds through air vibration is very promising means to perform the task of measuring vibration for structural health monitoring purpose as a non-contact, non-destructive method. However, challenges remain on developing proper algorithms to convert measured acoustic data to vibration measurements from the source. The XXX System, with its enrollment of approximately 2.5 million students, is in a prime position to grow the future science, technology, engineering, and mathematics (STEM) workforce. Through a U.S. Department of Education funded XXXXX program between XX, a Hispanic-Serving community college and XXXX, a public comprehensive university, a 10- week summer program is set up to provide opportunity for community college students to experience the excitement of the state-of-the-art research. As one of the Civil Engineering projects in this summer program, the community college students are working closely with graduate students at XXXX to investigate the possibility to use acoustic sensor for non-destructive structural health monitoring. After learning basic theory through a series of training workshops, the students performed experimental testing with an array of microphone sensors with various configurations on a single-degree-of-freedom (SDOF) structure exciting on a shake table. With the acquired data, several post-processing algorithms are proposed to extract the useful information and eliminate the noise.

In addition to the surveys, the participants were invited to participate in a 30-minute conversation about their summer internship experience to examine the internships’ impact on interviewees in terms of: i) engineering self-efficacy and commitment to engineering as a career; ii) academic goals, including interest in research; iii) career goals; and iv) network of/engagement with professionals from academia and industry. The feedback from students shows that the XXXXX program offers an effective way to engage students from community college in engineering research.
