Description

Technical field: [0001] The invention belongs to the technical field of vibration fatigue testing, in particular to an impact and heat composite testing device for fiber-reinforced composite thin-walled components. Background technique: [0002] Fiber-reinforced composite materials and their structures have high specific strength, high specific modulus, material designability, good thermal stability, and also have the advantages of large bearing capacity and light weight. They are widely used in aviation, aerospace, machinery, ships, etc. , sports equipment, electrical equipment, medicine, weapons industry and chemical industry and other fields. With the continuous improvement of modern industrial level, many fiber-reinforced composite thin-walled components, such as composite blades, composite blisks and composite cylindrical shells, often work in harsh environments such as high-speed rotation, high temperature, impact, and corrosive gas erosion. Among them, the problems o...

Problems solved by technology

Its structure is simple, but its function is single, and its scope of application is extremely limited. It can only be applied to apply impact in a vertical manner. The structure is not compact. If you want to obtain a large impact, you must have a higher drop height. The object cannot be separated from the tested material in time and effectively after the impact is applied, whether it is the secondary impact caused by the rebound or the impact object itself has a considerable impact on the accuracy of the test

Patent CN200910197140-1 proposes a high-speed steel ball impact test device, which uses the principle of electromagnetic induction to accelerate the steel ball, so it is difficult to guarantee the speed of the steel ball, the uncertainty is large, the thrust is small, and it is impossible to apply a large The impact is narrow, and the scope of application is narrow; patent CN201420808043, patent CN200320122091, patent CN201120441056, and patent CN201280060161 respectively provide different heating methods, but the structure is not compact enough, the space utilization rate is low, and most of them are used in special fields, and the versatility is low. The temperature control range is narrow and the control accuracy is low; and these patents are separate modules, it is difficult to combine the two together, and the function is single
