This data article comprises the experimental data during testing a vibration control technique for structural and mechanical systems which uses new passive vibrational control device called the linear particle chain impact damper (LPCID). The LPCID consists of freely moving spherical balls of different sizes arranged linearly inside a rigid container. The data were collected by taking precise measurements from a custom-designed experimental setup. The data were collected for a freely vibrating frame structure which was released from an initial position by an electromagnet. The data presented in the article will provide a path for researchers to validate the dynamic models for several types of impact dampers such as single-unit and multi-unit impact dampers. The data will also help in understanding the nonlinear behaviour of this type of impact dampers. The article also comprises data for examining the performance of the LPCID by varying the design parameters, including mass ratios, damper clearance and chain length. The article is related to research articles by Gharib and Karkoub (2017) .
