Abstract

The invention provides a positioning device for a strong loading experiment. The positioning device comprises a base, a positioning frame, a front supporting frame and a rear supporting frame. The base serves as the basis of the whole positioning device and is fixed on the vibration platform. The positioning frame is mainly used for fixing and positioning a measured object. The front support frameand the rear support frame limit the displacement of the positioning frame in the forced loading test process in two directions, so that the displacement of the tested object relative to the whole positioning device in the test process is limited to a great extent, and more accurate vibration characteristics can be obtained. Aiming at a high-frequency vibration experiment of the liquid carrying box body, the liquid carrying box body can be prevented from being damaged in advance due to resonance coupling in the experiment process, and the experiment accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical testing, and in particular relates to a positioning device for strong loading experiments, which is especially suitable for high-frequency mechanical vibration experiments of liquid-carrying boxes. Background technique [0002] Vibration is a common phenomenon during the use of equipment. Under high-frequency vibration, the structure of the equipment is prone to damage, and the operating performance of the equipment will also be affected. For the liquid-carrying tank, the liquid is likely to cause slamming to the local part of the tank under high-frequency vibration, affecting the overall force of the liquid-carrying tank and causing structural damage or destruction of the tank. In order to ensure the stable, safe and efficient operation of the liquid-carrying tank, it is necessary to carry out vibration experiments on the liquid-carrying tank. Typically, vibration experiments are performed on...
