    摘要: Method for predicting the overall hydraulic performance of a sink-type dishwasher. Process begins with unsteady numerical computation on a dishwasher pump under static conditions to obtain a characteristic pump curve. Using this curve, rotation velocity adaptation coefficient (Ad) and axial velocity coefficient (Bd) are determined. Mapping relationship is established between composite superposition virtual impeller and composite impeller. Passive rotation velocity of the volute and the nozzle flow rate are calculated using GMO model and virtual impeller. A jet mass source is established, using the nozzle flow rate and the volute's passive rotation velocity as boundary conditions. This leads to a non-submerged rotating jet flow computation with a multi-nozzle setup using the VOF method. This approach streamlines the dishwasher's intricate multi-physics, conserves computing resources, and effectively resolves issues related to free surface divergence and estimating the volute's passive rotation speed, leading to an accurate prediction of the dishwasher's overall hydraulic performance.

    摘要: A system, and the like, capable of improving efficiency when information regarding a component of a work machine is acquired using a terminal device having a wireless communication function, are provided. A first external request signal is transmitted from a terminal device 100 to an actual machine communication station 210 for which wireless communication with the terminal device 100 is established, in accordance with a designated communication format. The “designated communication format” is determined in accordance with a designated attribute designated through a terminal input interface 101 for a designated attribute item regarding a work machine 200. Further, a first external response signal regarding a communication state of an actual machine communication network in the designated work machine 200 on which the actual machine communication station 210 is mounted is transmitted from the actual machine communication station 210 to the terminal device 100.

    摘要: In order to monitor the condition of a machine, current operating data relating to the machine are continuously captured and are taken as a basis for continuously simulating a current operating behavior of a machine component by a concurrent simulation module. Furthermore, performance values quantifying a current performance of the machine component are continuously derived from the simulated operating behavior and are stored over time. In addition, a performance normal value is regularly determined on the basis of a multiplicity of performance values which were derived earlier. The operating data and/or the performance values are monitored in order to determine whether a predefined first change pattern occurs. Detection of the first change pattern then causes a performance reference value to be updated with the current performance normal value. In addition, the respective current performance values are continuously compared with the current performance reference value in each case.

    摘要: An abnormal sound detection device includes: a sound acquisition unit that obtains operation sound of a target apparatus as a sound pressure time signal that is a time signal indicative of a time variation in intensity of sound pressure signals; a signal transform unit that transforms the sound pressure time signal to a frequency characteristic indicative of intensity of the sound pressure signals at respective frequencies; an abnormal sound emphasis unit that obtains, based on the frequency characteristic, an abnormal sound emphasized signal obtained by emphasizing intensity of a sound pressure signal at a frequency in association with the abnormal sound of the target apparatus; and an abnormal sound determination unit that determines whether the abnormal sound is included in the operation sound based on the abnormal sound emphasized signal.

    摘要: A probe assembly for a test fixture for a heatsink, may include a thermocouple probe configured to measure a surface temperature of the heatsink. The probe assembly may include a base portion with an opening for receiving the thermocouple probe. The probe assembly may include a spring-loaded collet assembly connected to the thermocouple probe via the opening of the base portion and configured to cause the thermocouple probe to removably contact a bottom surface of a pedestal of the heatsink. The probe assembly may include a thermocouple cable connected to the thermocouple probe and configured to communicate the surface temperature of the heatsink.
