The invention relates to the field of deformation detection tools, in particular to a circular cylinder deformation detection tool.
Background
Products made of carbon fiber reinforced Composites (CFRP) are increasingly used in engineering machinery, aerospace and other industries by virtue of low density, corrosion resistance and high fatigue performance. The fatigue strength of the composite material is obviously improved, and the composite material is very expensive for structural members bearing variable-amplitude loads. In addition, the composite material has the advantages of impact resistance, injury tolerance (load can be borne after cracks are found, symptoms are also present before damage), secondary damage is small, molding and processing are easy, and the like, along with continuous and healthy and rapid development of economy, the demand of engineering machinery for infrastructure construction is greatly increased, while a hydraulic cylinder is a special part of various engineering machinery, coal mine machinery, special vehicles and large machinery, strict requirements are also provided for the arm extension height of the engineering machinery, but the problems of high weight, unsatisfactory strength, rigidity and fatigue resistance of all-metal hydraulic cylinders in the prior art are solved, and the all-metal hydraulic cylinders can not meet the use demands gradually, so that carbon fiber materials are excavated and applied gradually.
