CONTACT RESONANCE 101

Contact Resonance 101

Contact resonance can significantly damage measurement accuracy and even cause system failure. Interface 101 Series details how inherent mechanical clearances within the measurement system can turn harmless transient forces into potentially destructive oscillations. Contact resonance is a form of self-excited oscillation that occurs in mechanical systems involving mass, stiffness, and a clearance. Interface Load Cells 301 Characteristics and Applications Guide covers this important topic.
