Abstract
In this paper, the dynamic behavior of an airless wheel made by additive manufacturing is investigated. A lattice geometry is chosen as the cyclic pattern from which the wheel is built. Initially, a linear numerical model is used to preliminarily assess resonance frequency and mode shapes of the wheel. Afterwards, specimens were tested twice, in August 2020 and after six months, highlighting a relevant frequency and damping shift in the vibrational response. To better understand the reason behind the change over time in the wheel dynamic behavior, dedicated structural dynamics tests at varying temperature and humidity set points were performed in an environmental chamber, consisting in measuring the wheel vibrational response when subjected to temperature and humidity variation.
