Low dimensional modeling of a non-uniform, buckled piezoelectric beam for vibrational energy harvesting
نویسندگان
چکیده
A model is developed for a non-uniform piezoelectric beam suitable for analyzing energy harvesting behavior. System dynamics are projected onto a numerically developed basis to produce energy functions which are used to derive equations of motion for the system. The resulting model reproduces the experimentally observed transition to chaos while providing a conservative estimate of power output and bandwidth.
