“…However, there has been no estimation of impact loads transmitted to parts of a vibro-ripper during the crushing of rocks with eccentric rotational motion. In previous investigations of rock crushing systems, Ficarella et al [6][7][8] employed a one-dimensional hydraulic simulation and experiments to assess the performance and design method of a hydraulic breaker, while others have focused on improvements to impact performance, minimizing the weight of the breaker housing, and design optimization [9][10][11]. Other studies have focused on the development and improvement of vibro-ripper and hammer systems.…”

This study aimed to estimate impact loads delivered to vibro-ripper housing through link modules, together with loads transmitted in various directions. Housing vibration resulting from impact loads generated during the operating condition and frequency response functions were assessed by vibration and modal experiments, respectively. Vibration data and transfer functions were applied in a transfer path analysis (TPA) model to analyze the quantified impact loads transmitted through the key components of the vibro-ripper to its housing. Impact loads derived by TPA for different housing parts were compared with those in the tooth derived from load-cell measurements, validating the TPA method. As a result of the verification, the impact load calculated by the TPA method was 193.7 kN, whereas that from the striking force measured by the load cell was 220 kN, a difference of 12.3%. The results of this study may be important input values for numerical analysis in equipment design and can be used as key data for structural safety evaluation and optimization. In summary, this paper introduces the vibration-based TPA method and considers its applicability to construction machinery exposed to impact vibration and loads.
