Abstract: Provided are a device and a measuring method for measuring an unbalanced moment on a bottom surface of a circular valve core. The device includes a diverging shaped tube, a water tank, a transparent tube, spring dynamometers, laser sources, a circular valve core, and a high-speed camera with a camera stand. Inner shackles and the laser sources are evenly distributed on an outer side of the circular valve core of the device, the spring dynamometers are connected with the inner shackles and with the outer shackles evenly distributed on an inner wall of the transparent tube. The method records an unbalanced state of the circular valve core under an impact of water flow from different orientations with the high-speed camera on the camera stand, the location of the laser point on the outer wall and a tension force of the spring dynamometer are read to calculate a torque of the circular valve core.

Abstract: A zero-strain soil pressure sensor includes a shell provided with a hydraulic oil cavity and a cavity located below the hydraulic oil cavity, a processor, an outer elastic film arranged at the upper end of the hydraulic oil cavity, an inner elastic film arranged between the hydraulic oil cavity and the cavity, an outer strain bridge circuit connected with the outer elastic film, an inner strain bridge circuit connected with the inner elastic film, a piston communicated with the hydraulic oil cavity, and a driving mechanism connected with the piston. The outer strain bridge circuit, the inner strain bridge circuit and the driving mechanism are electrically connected with the processor. The invention has the beneficial effect that the piston is driven by the driving mechanism to control the oil pressure in the hydraulic oil cavity, external soil pressure is balanced through the oil pressure to keep the outer elastic film in an non-deforming state all the time, and only the inner elastic film is deformed, so that the soil arch effect and soil displacement are avoided, and thus the liquid pressure measured by the inner elastic film is the soil pressure, and the measurement result is more accurate.

Abstract: A thin film material residual testing structure comprises two groups of structures. The first group of structures comprises an electrostatic driven polysilicon cantilever beam, an asymmetrical cross beam made of thin film material to be tested and having an alignment structure, and a double-end fixed support beam made of the thin film material to be tested. The second group of structures is similar to the structure of the first group with the fixed support beam removed. A residual stress testing method includes separating the loading drive part of force from a residual stress testing structure made of the thin film material to be tested, designing the bending deflection of a control testing structure according to geometrical parameters, extracting the force applied on the residual stress testing structure and utilizing force and deflection to calculate the residual stress of the thin film material to be tested.

Abstract: A pressure sensor system comprises a force feedback loop. The force feedback loop is configured to receive a measured pressure sensor signal and generate a feedback signal based on the measured pressure and an electrostatic force. The electrostatic force is generated based on the feedback signal and combined with the measured force keeping the resultant sensor signal stable.

Abstract: An apparatus and method for performing a load test in an elevator installation having an elevator car and a counterweight, which are connected to one another by a supporting device, and a drive brake for halting the elevator car during a downwards journey. The apparatus has a connecting element for fastening to the counterweight, an element with spring properties and a tensioning device for installation in the elevator installation. One point of the tensioning means is fixed to a stationary point of the elevator installation via the element with spring properties. Another point of the tensioning means is connected to the counterweight via the connecting element, wherein the tensioning device includes an actuating device with which to tension the element with spring properties in order to thereby exert a downwardly directed tensile stress on the counterweight.
