This report summarizes a three year study of noncontacting coned-face mechanical seal dynamics. Both small perturbation and full non-linear analyses are presented. An experimental technique to measure relevant dynamic properties of elastomeric secondary seals is described. The critical speed, for the dynamic stability threshold, and the critical rotor runout are presented. It is shown that the more simple to use small perturbation analysis gives very good results for most practical cases. This document includes information on the following form areas 1 Stiffness and Damping Characteristics of Elastomer O-Rings Secondary Seals Subjected to Reciprocating Twist 2 A Kinematic Model for Mechanical Seals with Antirotation Locks or Positive Drive Devices 3 Stability Threshold and Steady-State Response of Noncontacting Coned-Face Seals and 4 Nonlinear Dynamic Analysis of Noncontacting Coned-Face Mechanical Seals.
