Special Issue Information

Dear Colleagues,

This Special Issue is devoted to the application of signal acquisition and processing in measurement and testing fields. The signal acquisition technique aims to acquire the analog signal, and it is governed by the Shannon sampling theorem. However, the rate of signal is usually high, and it brings a great challenge to the signal acquisition techniques. Therefore, the alternative signal acquisition techniques, such as sub-Nyquist sampling, compressive sampling etc., would be potential solutions to acquire the high speed signal. In this Special Issue, we will focus on the signal sampling methods and the corresponding processing techniques. The scope of submitted papers may encompass: (1) sampling models with mathematical explanations, particularly welcome will be models that could be implemented in circuitry. (2) signal reconstruction, representation and estimation; (3) design, circuitry implementation.

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. Full article
