Description

technical field

[0001] The invention relates to vibration testing equipment, in particular to an angular vibration table. Background technique

[0002] The angular vibration table is the key test equipment for testing the dynamic performance and anti-angular vibration interference ability of inertial devices and navigation equipment. With the continuous improvement of the dynamic performance and precision of inertial devices and navigation equipment, the requirements for the angular vibration table are also increasing, which requires the angular vibration table to have a higher excitation frequency, a larger stroke, and a smaller waveform distortion. The flexible hinge has the advantages of no gap and friction, no lubrication, and no wear. The voice coil motor has the advantages of simple structure, high precision, and fast response. Combining the two, a precision angular vibration based on the flexible hinge and voice coil motor is designed. The table, which can meet the n...
