The use of numerical optimization methods to select reciprocating engine anti-vibration characteristics is investigated. A rigid body power train model coupled through an arbitrary array of vibration isolators to a rigid supporting structure forms the basis of the dynamic model. By calculating the forced response of the power train to its internally generated excitation, the strain energy summed over the isolators may be determined. This energy, which is indicative of the efficiency of the vibration isolative mounts, is used as the objective function in the optimization procedure. The method is expected to be useful in preliminary design studies of front wheel drive vehicles where traditional methods of mounting automotive engines are not necessarily applicable. [Continues.]
