摘要:
涉及密封系统、激励和响应三者之间复杂关系的动力学特性,对非接触式机械密封的运行可靠性有着重要影响,是当下密封理论与技术领域研究的热点。本文回顾了近几十年来国内外非接触式机械密封动力学的发展历程,分析了非接触式机械密封系统动力学理论研究、实验研究和应用研究状况,探讨了基于非接触机械密封系统结构动力学特性和输入载荷的动、静环位移响应、流体膜厚度响应的研究特征以及流体膜刚度和阻尼、系统的固有频率与振型模态等特性参数的识别方法,指出了现有动力学研究存在的不足,提出多频激励耦合作用响应、动静环的碰撞机制、动力学参数的非线性识别方法、智能化、显著性影响因素分析和高参数工况下的非接触式密封性能试验台等研究是非接触式机械密封动力学今后一段时期的发展方向。
