摘要
The present work is concerned with the experimental investigation of damping at preloaded metallic interfaces subjected to cyclic tangential forces. The situations of various joint materials are compared. Predictive equations for damping in machined joints are developed based on experiments conducted on a rationale of economic data reduction through response surface methodology (RSM). Orthogonal first-order models are developed for energy loss per cycle of vibration in mild steel, grey cast iron and phosphor bronze joints and a central composite rotatable design in the case of aluminum alloy joints. A good correlation between the predicted and actual joint damping test results is obtained. The methodology presented suggests a useful technique for damping research.
