Abstract: A method for monitoring the balancing of the wheels of a motor vehicle, comprising at least a phase of modeling a first sinusoidal theoretical acceleration signal of a first wheel and a second sinusoidal theoretical acceleration signal of a second wheel, a noise-measuring phase including, for the first wheel, calculating the difference between the value of each sample of the first raw acceleration signal and a corresponding theoretical value of the first theoretical acceleration signal, then measuring a first standard deviation for the calculated differences, and, for the second wheel, calculating the difference between the value of each sample of the second raw acceleration signal and a corresponding theoretical value of the second theoretical acceleration signal, then measuring a second standard deviation for the calculated differences, a first step of calculating reference averages including calculating a first reference average of the first standard deviations and a second reference average of the second standard deviations, a second step of calculating a first current average of the first standard deviations and a second current average of the second standard deviations, and a diagnostic step to calculate a first variation between the first current average and the first reference average and a second variation between the second current average and the second reference average in order to detect a possible relative unbalance of the wheels.

Abstract: A vehicle component balancing robot apparatus, system and method for on vehicle balancing of one or more of a tire, a wheel, bearings, brake components, and vehicle components that impart vibrations to the vehicle. The apparatus includes a frame arranged so as to connect with the vehicle. A robot of the apparatus moves relative to the frame, and is configured so that the move, relative to the frame, resolves a predetermined location of a tire-wheel assembly relative to a reference frame of the robot. The robot has at least one end effector arranged to interface the tire-wheel assembly and the robot moves the at least one end effector to other predetermined locations on a wheel rim of the tire-wheel assembly, determined based on resolution of the predetermined location of the tire-wheel assembly relative to the reference frame.

Abstract: In a method for determining an equivalent modal unbalance for the first bending characteristic form of a shaft-elastic rotor, which unbalance is to be compensated for, a rotor model is created describing the geometric shape and material properties of the shaft-elastic rotor. The magnitude of compliance of the rotor model is calculated at a measurement point and at the center of gravity of the rotor at an assumed speed. The shaft-elastic rotor is received in a rotatable bearing and accelerated to the assumed speed which is below its first critical speed. Subsequently, the magnitude of outward deflection at the measurement point of the shaft-elastic rotor rotating at the assumed speed can be measured. The equivalent modal unbalance for the first bending characteristic form of the shaft-elastic rotor, which unbalance is to be compensated for, can be calculated from the magnitudes of the calculated compliance and the measured outward deflection.

Abstract: A method for monitoring an aircraft engine during flight, which includes the steps of: for at least one characteristic frequency of the operation of the engine, measuring at least one synchronous vibration level value; for at least one module of the engine, estimating an out-of-balance value of the module in accordance with the one or more vibration level values measured and at least one sensitivity coefficient; estimating a balancing margin of the module in accordance with the out-of-balance value of said module and a maximum threshold; (d) estimating a remaining number of flights of the aircraft prior to balancing and/or a quality indicator of a preceding balancing operation in accordance with the one or more estimated balancing margins and data representing past balancing operations of the engine.

Abstract: The present invention relates to a wind turbine rotor balancing method which compensates imbalances between the centers of gravity of the wind turbine blades, in both magnitude and position along said blades, so that the amount of mass needed to carry out this balancing method is minimized, while reducing the loads and vibrations associated with a position of the center of gravity of the rotor not aligned with the axis of rotation thereof, wherein the invention further relates to the wind turbine rotor balancing system and the wind turbine balanced with the above method.

Abstract: A vehicle computer is described that includes a processor and memory storing instructions executable by the processor. The instructions may include, to: determine a vehicle speed; determine, for a first wheel, a first vibration profile; determine, for a second wheel, a second vibration profile that includes a roadway disturbance input; and using the speed and the two profiles, determine a wheel imbalance at the first wheel.

Abstract: A method for the detection of the azimuthal angular position of a wheel imbalance in a wheel of a vehicle, in which the presence of a wheel imbalance is detected on the basis of the output signals of a wheel rotational speed sensor assigned to the wheel, at least one driving dynamics quantity describing the instantaneous driving situation is ascertained, and the azimuthal angular position of the wheel imbalance is ascertained as a function of the driving dynamics quantity.

Abstract: A device (10) and method for sensor diagnostic monitoring and detection of an imbalance of a rotating machine (1) has steps of (a) detecting acceleration signals (Sb) of the housing (2) or of a non-rotating component of the rotating machine (1) by a sensor (20); (b) detecting signals (Sd) for the determination of the rotation speed of the rotating machine (1) by a second sensor; and (c) supplying and evaluating of sensor signals (Sb, Sd) by an evaluation unit (40, 50, 60). An acceleration component that is acquired occurs with the rotation speed of the rotating machine. This component is compared with a predetermined limit value.
