HARDNESS TESTING SYSTEMS
A system for measuring a mechanical property of a material or component under test comprises a hardness testing device with a computing device. The hardness testing device is configured to measure at least one measurement value indicative of a hardness of a material or component under test. The computing device includes a display, a processor, and memory. The memory has instructions that, when executed, cause the processor to control the hardness testing device to measure a measurement value indicative of hardness of a material. Executing the instructions further causes the processor to control to save testing data to a database. The computing device accesses the database, calculates a parameter related to hardness, and displays at least one of the portion of the database and the parameter related to hardness.
Method for testing and extracting paleo-tectonic geostress based on rock core
A method for testing and extracting paleo-tectonic geostress based on rock core, including: selecting rock cores in different tectonic periods; preparing standard cylindrical samples from the rock cores in a specific orientation; subjecting the samples to an acoustic emission test to test paleo-stresses of multiple tectonic periods and obtain paleo-tectonic stress data sequence; based on a correlation analysis and an Euclidean distance of the stress data sequence, stripping and extracting multi-level Kaiser stress points of the acoustic emission of rock cores from different formations, so as to calculate and evaluate the ground stress of an evaluated formation in an evaluated paleo-tectonic period.
Bulk crush strength test apparatus
An apparatus for use in testing the bulk crush characteristics of pellet materials. The apparatus constructed such that opening and closing can be conducted without complex binding and unbinding requirements. The apparatus may be used in combination with a universal testing machine fitted with compression test plates and a load cell capable of measuring force in a vertical direction.
SHEAR HEAD DEVICE
The shear head device includes a monitoring head having geophones and transmitters inside a cylindrical body. A shear head is coupled to the monitoring head from below. The shear head has a tubular structure with a plurality of apertures formed around an outer surface of the tubular structure. A plurality of cones are coupled with modified tips and disposed within the plurality of apertures. A sheet supports the plurality of cones inside the shear head. The sheet is selectively movable between a first radial position and a second radial position for the modified tips to apply radial force to the rock by adjustment of an internal pressure of the shear head. The transmitters transmit the recorded acoustic emission to a computing system for determining properties of the rock while the shear head device is testing the rock in the bore.
Loading device for measuring stiffness of structural member over time, monitoring system, and method thereof
A loading device, a monitoring system, and a method thereof can measure stiffness of a structural member (SM) and monitor progress or property thereof over time. The loading device includes two types of displacement sensors, one type being an antenna. As the SM, which is in a magnetic or electromagnetic field and electromagnetically coupled to the antenna without contact, undergoes displacement under known loads, characteristics of the electromagnetic field coupling between the antenna and the SM change over time due to the displacement of the SM. The shift in the characteristics of the electromagnetic field coupling between the antenna and the SM can be used to determine the displacement of the SM. Based on the changes in the displacement over time, diagnosis of the SM being monitored over an evaluation period can be made. The loading device includes at least one movable frame to apply a preload to the SM.
ARTICLE ORIENTATION CHANGE DEVICE
An article orientation change device 30 includes a flap 11 is provided so as to be vertically swingable about a swing shaft 13 as a fulcrum, a conveying member 25 that pushes out a tablet W to a predetermined position on the placement surface 11a, and a pressing member 12 that presses the tablet W against the wall portion 1A, in which a tapered surface 25A is provided on a facing surface of the conveying member 25, the conveying member 25 conveys the tablet W to the placement surface 11a to push out the tablet W to the predetermined position in a state where the tablet W maintains the first orientation, and the pressing member 12 moves in a direction approaching the wall portion 1A to change an orientation of the tablet W on the placement surface 11a from the first orientation to a second orientation.
STRENGTH MEASURING APPARATUS AND STRENGTH MEASURING METHOD
The strength measuring apparatus includes: a strength measuring instrument measuring the strength of the mold on the basis of a reaction force received from the mold; a moving unit moving the strength measuring instrument; a distance sensor measuring a distance to an object on the conveyance line; and a control unit controlling the moving unit, wherein the control unit determines a measurement position of the strength measuring instrument in a horizontal direction perpendicular to a conveyance direction of the conveyance line on the basis of the distance detected by the distance sensor and controls the moving unit to move the strength measuring instrument to a position above the measurement position.
