Description
Technical Field
The invention relates to mechanical experimental equipment, in particular to an electron irradiation in-situ stretching compression experimental device and method.
Background
The space material needs to be in service in space for a long time and is subjected to complex space environment effects, wherein the electron irradiation effect is a common irradiation form, and in ground experiments, an equivalent fluence method is commonly used for carrying out electron irradiation experiments. Therefore, the electron irradiation experiment has wide application in the field of aerospace material testing. The properties of materials may change after being subjected to electron irradiation, and changes in mechanical properties are a major concern. In order to study the change of mechanical properties of materials, a common method is to conduct a tensile compression experiment on a material sample before and after irradiation and compare the tensile compression experiment. During the process of the electron irradiation experiment, operators must be far away from the electron irradiation device due to the radiation effect, and effective physical isolation exists between the operators and the equipment. On the other hand, because the electronic equipment is interfered strongly in the electron irradiation process, the data transmission of the electronic equipment such as an actuator, a sensor and the like can be interfered, and even the normal operation of the electronic equipment is affected. In order to obtain the data of the change of the mechanical properties before and after the electron irradiation, the prior technical scheme is as follows: preparing a batch of experimental samples under the same condition, and carrying out stretching and compression experiments on a certain number of experimental samples which are not subjected to electron irradiation by adopting a universal material tester to obtain a group of experimental data; and then, a certain amount of experimental samples are sent to an electron irradiation device for electron irradiation with a certain dosage, and after the dosage irradiation experiment is finished, a universal material tester is used for carrying out a stretching compression experiment to obtain irradiated experimental data. The two sets of experimental data were then compared to verify whether the electron irradiation had an effect on the change in mechanical properties of the experimental samples. In this case, there is a problem that the time-effectiveness of the mechanical load test performed by taking out the test specimen is required because the test specimen may have an "annealing" effect after irradiation. For the specific aging effect of different materials and the magnitude of the time effect, no comprehensive systematic research has been disclosed at present, and the experimenter cannot study each material due to the problem of cost. In addition, because the electron accelerator and the electron irradiation device have complex structures, the operation steps are complicated, certain safety operation rules are required to be followed, and the starting-up and the shutdown cannot be carried out at will. Therefore, in the existing electron irradiation experiments, electron irradiation with a certain dose or fluence is generally only performed, and the irradiation intensity needs to be set in advance. Thus, the data obtained for the effect of electron irradiation on the mechanical properties of the material are discrete. Furthermore, scientists sometimes need to study the coupling effect of preloading and electron irradiation. In the existing practical operation, the test sample is generally loaded into a designed mechanical device, then a mechanical load is applied in advance, then the test sample is put into an electronic irradiation device for irradiation, and after a certain dose of irradiation is completed, the test sample is taken out for mechanical loading. There is a problem in that the mechanical load applied is fixed and cannot be adjusted during irradiation.
The problem that the timeliness influence and the fixed mechanical load caused by the annealing effect in the two methods cannot be adjusted in the experimental process restricts the related research of the influence of the electron irradiation on the mechanical properties of the materials. How to carry out in-situ mechanical loading experiments on the material in the process of receiving electron irradiation to obtain corresponding experimental data is a technical problem to be solved by the invention.
