摘要： A material testing apparatus and methods of testing material are disclosed. The material testing apparatus may include a support ring contacting a test material and a moveable contact component positioned adjacent to the support ring. The moveable contact component may include a substantially curved contact surface comprising a radius-varying curvature profile formed between a center and a perimeter of the substantially curve contact surface. The curvature profile may be based on a predetermined deflection-force profile specific to the test material. Additionally, the curvature profile may also be based on the material characteristics of the test material, the physical characteristics of the test material, the physical characteristics of the support ring and/or a testing process performed on the test material.

摘要： Methods, systems, and apparatuses for determining a flexibility value K of a fastener. An illustrative system includes a test apparatus including three straps with a strain gauge coupled to each strap. A fastener, such as a bolt, is installed through the straps, with a tensile or compressive force then applied to the test apparatus. Responsively, the strain gauges generate signals indicative of elastic deformation of the straps. The signals are transmitted to a signal processor, which may display deformation values, or alternatively, may process the signals to calculate the value K. The elastic deformation values acquired from the strain gauges, together with cross sectional area and elastic moduli of the straps, are entered into a calculation which applies a predetermined relationship to arrive at the value K. The test apparatus may be a stand-alone device for use in calculating the value K.

摘要： Disclosed herein is a test apparatus for early landslide detection fully-connected with pore water pressure, surface displacement and shear surface. The test apparatus calculates a factor of safety of a slope based on variation in pore water pressure, surface displacement and shear surface of a soil mass, and predicts a change in factor of safety, thus making early landslide detection possible. In the test apparatus, while a container of a slider is moved with a soil mass loaded into the container, shear surface and surface displacement environment is provided, and the shear strength and the shear stress of the soil mass can be calculated based on the pore water pressure and the weight of the soil mass. Thereby, the factor of safety of the soil mass can be calculated, and early landslide detection can be realized by using variation of the factor of safety of the slope.

摘要： The present disclosure relates to a simulated impact-type rock burst experiment apparatus comprising a bracket, a specimen box assembly, an X-direction, Y-direction and Z-direction loading mechanisms mounted on the bracket, and control systems. Loading mechanism comprises: four supporting posts in a rectangular arrangement, a first and second frames aligned with each other and fixedly connected to both ends of the four supporting posts, a loading hydraulic cylinder and a lead screw mounted on the two frames respectively. The present disclosure is able to load static and dynamic loads to the rock sample in three directions perpendicular with each other, thereby performing experimental method for simulating an impact rockburst. Furthermore, the structures of the three sets of loading mechanisms are substantially the same, which have good symmetry, therefore, it is more easily and accurately to control the operation for loading static or dynamic load to the rock sample.

摘要： An electrical conductor includes an electrically non-conductive plate, an electrically conductive pin extending through the plate, and a frame member fitted around an outer edge of the plate. The frame member is configured to pre-load the plate with a compressive stress. In particular, the frame member may pre-load the plate with the compressive stress that is sufficiently high enough such that a sum of the compressive stress, tensile stress, and shear stress components generated in the plate under high-pressure conditions is compressive overall.

摘要： A method for enabling a MIMO operation mode in a multimode communication terminal includes switching a first channel module to have parameter characteristics consistent with those of a second channel module, so that the multimode communication terminal enables the MIMO operation mode by using the first channel module and the second channel module at the same time. The method also includes extracting corresponding parameters from the second channel module and configuring the first channel module to be switched with the extracted parameters, such that the first channel module and second channel module enable the multimode communication terminal to perform MIMO communication. The method further includes issuing, upon determination of a switch, notification instructions to means in channel switch layer means and changing a data channel associated with the first channel module, such that the first channel module and second channel module can be adapted to the MIMO operation mode.
