928 - Noise reduction mechanisms of a spring wound LDT for a reciprocating compressorâ
Wang S., Park J.
Abstract
Dynamic behaviors of the impact damper working on horizontal environments have been studied with experimentally and numerically. Accelerated mass loading which phenomenon deteriorates the performance of the impact damper as it undergoes resonance vibrations is presented in experiments for a specific application of impact damping along with effect of the system parameters on the performance. In the numerical modeling, conservation of the momentum is employed. And, numerical study of the transient analysis using 4th-order Runge-Kutta method demonstrate general performance of the system, and shows that accelerated mass loading phenomenon is deeply related with the vibration level and mass of the auxiliary system. To explain accelerated mass loading, impact with zero coefficient of restitution (e = 0), sticking contact, is utilized along with conventional inelastic impact (0
