Abstract: A method of balancing an assembly of a wheel and a tire, may include measuring a maximum-value position of RFV of a tire and marking the measured maximum-value position, as a tire reference position, measuring each of the internal runout and external runout of the wheel, extracting a primary component of a waveform of the measured internal runout and a primary component of a waveform of the measured external runout and setting the former and latter measured primary components to be internal and external runout waveforms, respectively, synthesizing the internal and external runout waveforms and marking a minimum-value position on a synthesis waveform resulting from the synthesizing, as a wheel reference position, and aligning the tire reference position on the tire and the wheel reference position on the wheel to have the same phase and assembling the wheel and the tire.

Abstract: A vibration-cancelling module includes a first rotor having a first eccentric body, a second rotor having a second eccentric body, and a stator assembly in electromagnetic communication with the first and second rotors. A central shaft extends between the first and second rotors. The first and second rotors rotationally operate about a common rotational axis with respect to one another between a balanced position and a plurality of eccentric positions. A controller has an accelerometer assembly and a rotor-position sensor assembly. The controller delivers an electrical current to the stator assembly at least based upon the accelerometer assembly. A common housing contains the first and second rotors, the stator assembly, the central shaft and the controller.

Abstract: A method of forming a balanced rotor blade assembly includes measuring a weight of a plurality of sub-components of the rotor blade assembly excluding a core. A configuration of a core of the rotor blade assembly is determined. In combination, the core and the plurality of sub-components achieve a target weight distribution and moment. The core is then fabricated and assembled with the plurality of sub-components to form a rotor blade sub-assembly.

Abstract: The present application discloses a method for detecting an abnormity in an optical path or measuring and adjusting of a dynamic balance of a gantry in a CT system, comprising performing, by a gantry controlled by a controller, a test scan along an optical path of the CT system, the optical path being a path along which rays pass from a ray source to a detector. The method further comprises obtaining, by a processor, data relating to the test scan, and based on the data relating to the test scan. The method further comprises determining, by the processor, a status characteristic index of the optical path or an amount of dynamic imbalance of the gantry. The method further comprises analyzing, by the processor, a result of the status characteristic index; determining, by the processor, whether the optical path is abnormal, or determining whether a dynamic balance of the gantry satisfies a requirement based on a result of the analysis of the amount of dynamic imbalance.

Abstract: An angle-measuring device includes a housing and a position sensor configured to generate angle values indicating an angular position of a shaft with respect to a reference position. An interface is configured to communicate with subsequent electronics via a data channel. At least one imbalance sensor is configured to generate an imbalance signal from imbalance-induced excursions of the shaft. An imbalance analyzer is configured to generate imbalance values from the imbalance signal. A signal processor is configured to generate imbalance information from the angle values and the imbalance values. The imbalance information is transmittable through the interface to the subsequent electronics.
