The invention provides a connector detection device, which comprises a force hammer, a piezoelectric acceleration sensor and a processor, and is characterized in that the force hammer is used for applying a knocking force to a mechanical component to which a connector is fixedly connected, measuring an excitation signal corresponding to the knocking force and sending the excitation signal to the processor, wherein the connector and the mechanical component to which the connector is fixedly connected form a connecting system; the piezoelectric acceleration sensor is used for measuring the vibration acceleration of the connecting system when the force hammer applies the knocking force to the mechanical component to which the connector is fixedly connected, converting the vibration acceleration into a response signal and sending the response signal to the processor; and the processor is used for receiving the excitation signal sent by the force hammer and the response signal sent by the piezoelectric acceleration sensor, acquiring a mechanical impedance curve according to the excitation signal and the response signal, and judging whether a connector in the connecting system gets loose or not according to the mechanical impedance curve. The connector detection device provided by the invention improves the detection efficiency of connectors and improves the accuracy of a detection result.
Description
technical field [0001] The invention relates to mechanical measurement technology, in particular to a coupling detection device. Background technique [0002] In the field of mechanical structures, connectors are often required to be connected between various components. These connectors generally play a role of connection and fixation. Once the connectors become loose, it may cause failure of the entire mechanical structure. For example, in a wind turbine, the bolts at the flange connection of the tower and the blade connection bolts are important joints of the wind turbine, and the reliability of the connection determines the overall reliability of the entire wind turbine. Due to the vibration generated during the operation of the wind turbine If the frequency is high, the bolts at the flange joints of the tower and the connecting bolts of the blades are easy to loosen, resulting in the collapse of the wind turbine and damage to the blades. Therefore, it is necessary to fr...
