概要
- 論文の詳細を見る
Tightening pressure of gland packings decreases with time owing to stress relaxation of the packings. In the first step toward the analytical prediction of the stress relaxation in real tightening operation of gland packings in stuffing-box seals, the relaxation behavior of gland packings is examined both bxperimentally and theoretically. Stress relaxation tests were conducted on kland packings of asbestos and graphite. A viscoelastic model is presbnted for a dbscription of the stress relaxation of packings. This model can simulate satisfactorily the stress response of packings,especially in repeated tightening operation.
