Embodiment Construction

[0028] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the following only describes the features of the present invention that are different from the prior art, and the technical features that can be found in the prior art will not be repeated here.

[0029] For ease of understanding, the basic principle of the present invention is briefly described first. The three-dimensional space vibration measuring device of the present invention uses three pull-wire displacement sensors to measure the vibration displacement signals of the measured object in the corresponding three directions, and then uses the spatial coordinate transformation method to convert the signals of the three pull-wire displacement sensors into three Vibration displacements in two mutually perpendicular degrees of freedom.

[0030] First refer to figure 2 , introduce a preferred embodiment of...

Abstract

The invention provides a three dimensions vibration measuring apparatus and a measuring method. The test vibration apparatus comprises a support, three stay-supported displacement sensors and a processor, wherein the support has three installation parts which are respectively positioned on three mutually perpendicular axes (x, y, z) in a three dimensions coordinate system, each stay-supported displacement sensor comprises bodies (4,5,6) and stay wires (4(,),5(,),6(,)) drawn from the body, the bodies are respectively provided on the installation parts, the ends of the stay wires can intersect at a measuring point (7) in the space restricted by the bodies and the origin (O) of the three dimensions coordinate system and the processor communicates with the three stay-supported displacement sensors through an acquisition apparatus and processes the data obtained. According to the three dimensions vibration measuring apparatus and method provided in the invention, the processing towards a measuring signal is simple and direct, more precise vibration displacement values can be acquired. Besides, the vibration measuring apparatus is characterized by simple structure, convenient installation and low cost and the vibration measuring method is characterized by simple operation and easy implementation.

Description

technical field [0001] The invention relates to a three-dimensional space vibration measuring device and method. Background technique [0002] In the field of heavy industry machinery, some complete machines (such as pump trucks) have long boom structures. There is more or less vibration at the end of the long boom structure during work, which may affect the positioning of the working face and may cause safety accidents. After the design and development of the whole machine, it is necessary to carry out this test before leaving the factory to ensure the normal use of users. However, in vibration testing, single-degree-of-freedom vibration measuring devices are relatively common, while three-dimensional space vibration measuring still lacks corresponding devices and methods. [0003] In the prior art, the following two methods are generally used to test the vibration: (1) the existing remote vibration test generally firstly measures the acceleration signal of the measured o...
