摘要： A device, system, and method are provided for providing vibration data for rotating machinery. A sensor device is provided as a one-piece unit that is mechanically mounted to a pump. The sensor includes a vibration sensor, a processor, a wireless communications interface for exchanging data with a user device, and an internal battery. The processor is configured to receive a measurement request from the user device via the wireless communications interface. In response, the processor is further configured to configure the vibration sensor, receive data samples for multiple axes from the vibration sensor, and calculate a component velocity root mean square (vRMS) value, from the data samples, for each of the multiple axes. The processor may combine the component vRMS values into a sample vRMS value, and send a final vRMS value, based on the sample vRMS value, to the user device via the wireless communication interface.

摘要： A “periodic signal parameter” (PSP) indicates periodic patterns in an autocorrelated vibration waveform and potential faults in a monitored machine. The PSP is calculated based on statistical measures derived from an autocorrelation waveform and characteristics of an associated vibration waveform. The PSP provides an indication of periodicity and a generalization of potential fault, whereas characteristics of the associated waveform indicate severity. A “periodic information plot” (PIP) is derived from a vibration signal processed using two analysis techniques to produce two X-Y graphs of the signal data that share a common X-axis. The PIP is created by correlating the Y-values on the two graphs based on the corresponding X-value. The amplitudes of Y-values in the PIP is derived from the two source graphs by multiplication, taking a ratio, averaging, or keeping the maximum value.

摘要： A system according to the principles of the present disclosure includes a vibration level module and an engine operation control module. The vibration level module estimates a first level of vibration in a vehicle due to contact between tires of the vehicle and a road surface as the vehicle travels over the road surface. The vibration level module estimates a second level of vibration in the vehicle due to an engine in the vehicle. The engine operation control module selectively adjusts at least one of a speed of the engine and a load on the engine when the second vibration level is less than the first vibration level.

摘要： A vibration testing device to test vibration strength and frequency generated by an electronic device, includes a base, a vibration contact member, a transmission member, and a resilient member attached to the transmission member. The base includes a receiving space to receive the electronic device and a receiving hole in communication with the receiving space. The transmission member extends through the receiving hole and is rigidly attached to the vibration contact member. During testing, the electronic device directly abuts an end portion of the transmission member so that the vibration strength and frequency generated by the electronic device are directly transmitted to the vibration contact member.

摘要： A method of matching sensors in a multi-probe blade vibration monitor for a turbine. The method includes providing at least two probes mounted in a casing of the turbine adjacent to a rotating blade structure of the turbine. Targets are provided on radially outer portions of the blade structure. Each of the probes includes a sensor generating signals corresponding to target passing events, and a set of synchronous harmonics of the rotational speed of the rotor are produced for each sensor. The position of the sensors is adjusted such that the sets of harmonics of the sensors are substantially matched, indicating that the positions of the sensors are matched.

摘要： Tone color data are stored in a tone generator storage region of a RAM. The tone generator data storage region is searched upon occurrence of performance information indicative of a change of tone color, to determine whether tone color data selected by the change of tone color are stored in the tone generator data storage region, and musical tone generation is controlled such that when a result of the searching indicates that the tone color data selected by the change of tone color are stored in the tone generator data storage region, a musical tone is generated based on the tone color data, and, when the tone color data selected by the change of tone color are not stored in the tone generator data storage region, the tone color data are read out from a storage medium storing the selected tone color data, and transferred to and stored in the tone generator data storage region, while generating a musical tone based on other tone color data similar to the selected tone color data.
