摘要
为深入研究航空作动器往复密封的问题,对航空用直线往复作动筒上的VL密封圈进行有限元仿真。介绍VL密封圈仿真过程,建立密封圈划分网格后的有限元模型。通过对VL圈施加流体压力渗透载荷,对密封圈不同油侧压力下的应力应变情况进行分析,利用ANSYS APDL绘制密封圈唇口接触压力分布图,并分析密封圈最大等效应力及唇口接触压力峰值随温度的变化情况。仿真结果表明,该研究对于掌握VL型密封圈的力学特性有一定的参考价值。
In order to study reciprocating seal of aircraft actuator deeply,the finite element simulation of VL seal ring on linear reciprocating actuator for aviation was carried out.Introduced the simulation process of VL seal ring,and the finite element model of the meshed seal ring was established.By applying fluid pressure penetration load to the VL ring,analyzed the stress and strain of the seal ring under different oil-side pressure,and draw the corresponding lip contact pressure distribution curves in ANSYS APDL respectively,the tendency of maximum equivalent stress and peak lip contact pressure of the seal ring with temperature has also been analyzed.The simulation results show that the test has a certain reference value for understanding the mechanical characteristics of VL seal ring.
