Stiction testing
WebJan 13, 2014 · Stiction Any two surfaces in contact display two coefficients of friction at the interface: the static coefficient of friction (stiction) and the sliding coefficient of friction. In this case, stiction is the holding force that must be overcome before the axis can begin to … Webcontrol system. This paper presents a method to detect and quantify stiction based on normality test and Hammerstein system identification. Detection and quantification are showed by the B æ and B × parameters, where the value of B æ and B × greater than 0 indicate the valve suffer from stiction.

Like deadband, stiction causes a valve not to move, but instead “stick” in a particular position. Moving the valve requires additional force, which, also like deadband, can lead to the valve overshooting its position and the process overshooting its setpoint.

Detection and quantification are … WebThe click/buzz test doesn’t energize the injector coil long enough to overcome cold (engine oil temperature <80º F) stiction. Therefore, engine tests such as click/buzz or power balance to diagnose stiction will give misleading results and should not be used to identify stiction injectors on a cold engine. non-STICTIon RELATED ConDITIonS:
