Description
Technical Field
The invention belongs to the technical field of neutron diffraction in-situ environment loading, and particularly relates to a multidimensional stress loading experimental device for neutron diffraction measurement.
Background
The multidimensional stress loading experimental device for neutron diffraction measurement is matched with a neutron stress spectrometer, can be used for measuring stress distribution conditions of component manufacturing materials such as aviation wings, engines and high-speed rail under the conditions of service conditions and temperature, and plays a guiding role in component material selection, aging mechanism, processing technology and the like. In order to accurately measure the deformation condition of a sample, a conventional material testing machine device often uses sensors such as an extensometer to directly measure, and in neutron diffraction measurement application, on one hand, an environment loading experimental device needs to reserve a neutron beam line channel, and meanwhile, the size of the device is limited by a sample table, the beam height and the like, so that the problem that the extensometer cannot be installed or is complicated to install is caused, and the deformation measurement of the sample can only be indirectly obtained through a driving motor end. The in-situ testing device (CN 207423647U) for mechanical properties of variable-temperature tension-torsion composite load materials disclosed in the Chinese patent literature library is not provided with a deformation measurement related sensor, and the deformation condition of a sample can be obtained only through the ends of driving motors. On the other hand, in the case of sealing loading such as oxidation resistance and ice resistance, the use of conventional measuring sensors such as extensometers can damage the sealing structure and cannot meet the requirements. The patent 'in-situ heating device for neutron diffraction' (ZL 201720225423.2) disclosed in the Chinese patent literature library proposes the structural design of an in-situ temperature loading device for strain measurement by using an extensometer, but the structure is not suitable for measuring torsional deformation, and the structure of arranging a measuring hole of the extensometer on a heating body cannot meet the requirement of sealing loading.
