Abstract

The invention belongs to the technical field of detection, and discloses a mass distribution identification method, device and equipment of a composite material beam and a storage medium, and the method comprises the steps: obtaining a front-order modal function of a composite material cantilever beam; wherein the positive integer is a preset positive integer and is greater than 1; according to the front-order modal function, solving a Legendre orthogonal polynomial-based main mass orthogonal equation to obtain a front-order Legendre polynomial coefficient; based on a Legendre orthogonal polynomial, calculating the linear density of the composite cantilever beam according to the Legendre polynomial coefficient of the front order; therefore, the mass distribution condition of the composite cantilever beam can be accurately identified.

Description

technical field [0001] The present application relates to the field of detection technology, in particular, to a method, device, equipment and storage medium for identifying mass distribution of composite material beams. Background technique [0002] Because composite materials have composite properties such as layered or fiber braided, their density presents spatial distribution characteristics. In order to study the mechanical properties of composite cantilever beams, mechanical modeling is generally performed on composite cantilever beams. Traditional modeling methods usually set a series of parameters according to structural parameters such as isotropy or anisotropy, but do not consider the spatial distribution of density. The established model cannot more accurately describe the mechanical properties of composite materials. Contents of the invention [0003] The purpose of this application is to provide a method, device, equipment and storage medium for identifying t...
