Self-Tuning Torsional Vibration Dampers for V8 Engines
The problem of crankshaft torsional vibrations for heavy car engines is important for the V8 engines. The paper describes the results of the dynamical study of the new patented Torsional Vibration Dampers mounted on a crankshaft in V8 engines. Design and structure of Torsional Vibration Damper is based on author’s US Patent 7,438,165 having the control system with instantaneous frequencies tuner for all frequencies of running engine. Analysis and disadvantages of conventional rubber and viscous Crank Dampers are shown. The focus of the study is on Torsional Vibration Damper having the mechanical self-tuning structure applicable for V8 engines. Mathematical model based on the system of ordinary differential equations describing the rotation and vibration of mechanical components has been used for the analysis of the dynamic behavior of V8 engine crankshaft system having proposed Torsional Vibration Damper.
