Embodiment Construction

[0017] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and several preferred embodiments.

[0018] As an aspect of the present invention, the inventor of this case provides a method for testing the overall vibration of super-large structural parts, including:

[0019] Discretely set a plurality of sensing units on the overall surface (including the outer wall and inner wall) of the super-large structural part and / or inside the overall structure (that is, make the detection range of the plurality of sensing units completely cover the surface and interior of the super-large structural part ), and when super-large structural parts are subjected to external forces (for example, forces generated by factors such as wind, water flow, pedestrians or vehicles passing by buildings, earthquakes, or decoration construction, and transmitted to super-large structural parts) In this case, the plurality of sensing u...

Abstract

The invention discloses a whole-body vibration testing system and a whole-body vibration testing method for an ultra-large structural member. The method comprises the following steps of: providing a plurality of sensing units, wherein the monitoring range of the sensing units is enough to fully cover the whole-body surface and/or internal part of the ultra-large structural member, and under the situation that the ultra-large structural member is under the effect of external force, the sensing units are used for detecting the response parameters of all parts of the ultra-large structural member; and using at least one data processing unit to receive and process detection signals output by the sensing units, constructing a real data model for the ultra-large structural member and deducing the excitation characteristics of the ultra-large structural member. By using simple equipment, the whole-body vibration testing of the ultra-large structural member can be conveniently and rapidly realized, testing results which are basically consistent with real situations are obtained and the system and the method are suitable for the vibration testing of ultra-large structural members of all kinds.

Description

technical field [0001] The invention relates to an environmental vibration test equipment and method, in particular to a system and method for performing a vibration test on the overall structure of a large building, a large ship, a large flying object, etc., and belongs to the technical field of vibration test. Background technique [0002] At present, for super large structural parts such as large buildings, large ships, large flying objects, and offshore drilling platforms, it is generally difficult to use vibration test equipment to test their overall structure. Parts are tested, and then the test data is integrated to deduce the overall performance of these super-large structural parts, or only by building simulation models of these super-large structural parts, and then using these simulation models for vibration tests to infer these super-large structural parts overall performance. However, the test results obtained by these methods are often far from the real situat...
