Abstract
The invention discloses an elastic deformation measuring method. A deformed object, a spring and a pressure meter are used in the method. Deformation displacement is measured by measuring pressure of the deformed object on the spring. Distance is measured by measuring force so as to measure the elastic deformation of the object. The elastic deformation measuring method has the advantages of being simple in tool and convenient.
Description
Technical field
The invention belongs to the mechanical deformation fields of measurement, particularly a kind of elastic deformation measuring method.
Background technology
Traditional elastic deformation measuring method mainly adopts pulling method, measures elastic deformation by the mode of range finding, and the defective of the method is.Survey instrument and measuring process more complicated, and by acting force of the spring and the proportional characteristic of deformation, can realize by the mode of dynamometry range finding, thus measure the elastic deformation of object.
Summary of the invention
Order of the present invention is to provide a kind of elastic deformation measuring method.
The technical scheme that realizes above-mentioned purpose is: a kind of elastic deformation measuring method, comprise changing object, spring and pressure gauge, and described spring one end is pressed on the described changing object, and the other end is pressed on the described pressure gauge.
Above-mentioned a kind of elastic deformation measuring method, wherein, described changing object produces strain, and the dependent variable of generation is directly proportional with the displacement that produces at described spring.
Above-mentioned a kind of elastic deformation measuring method, wherein, the displacement that produces on the described spring is directly proportional with described pressure gauge institute measuring pressure.
Above-mentioned a kind of elastic deformation measuring method wherein, is calculated the changing object dependent variable according to described pressure gauge institute measuring pressure.
The invention has the beneficial effects as follows: the present invention realizes range finding by the mode of dynamometry, thereby measures the elastic deformation of object, has the advantages that instrument is simple, method is easy.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
See also Fig. 1, provided a kind of elastic deformation measuring method among the figure, comprise changing object M, spring K and pressure gauge V, spring K one end is pressed on the described changing object M, and the other end is pressed on the pressure gauge V.
Changing object M produces strain, and the dependent variable X of generation is directly proportional with the displacement Y that produces at spring K, and ratio is k, then gets formula 1:Y=kX.
The upper displacement Y that produces of spring K is directly proportional with the measuring pressure F of pressure gauge V institute, and ratio is g, then gets formula 2:F=gY.
Formula 1 variable substitution formula 2 can be got formula 3, and F=kgX can calculate changing object M dependent variable X by the measuring pressure F of pressure gauge V institute according to formula 3.
Below embodiment has been described in detail the present invention by reference to the accompanying drawings, and those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details among the embodiment should not consist of limitation of the invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
