ABSTRACT: Modern advances in microtechnology have facilitated the development of compact, cost-effective,
integrated accelerometers and gyroscopes that are suitable for investigating the motion of various structures, mechanisms, and machines. This paper presents an experimental setup for recording large oscillations of a two-degree-of-freedom spring system. Two 3D accelerometers and 3D gyroscope modules, a low-cost microcontroller, and a wireless communication modules are used. The experiments show that measurements that use integrated digital accelerometers to investigate the kinetics of such a class of mechanical systems allow for a significantly more comprehensive analysis of their behavior than traditional measurements.
