摘要
针对唇形密封圈性能评估过程繁琐且效率低的问题,基于唇形密封圈物理模型与Femap&NX Nastran平台,研究了基于物理模型的唇形密封圈静密封性能快速仿真流程定制技术。首先,基于Mooney-Rivilin模型的橡胶材料本构关系,利用有限元分析软件建立唇形密封圈的轴对称数值模型,针对该模型的非线性问题,采用收敛控制技术取得了良好的收敛性;通过有限元模拟获得了唇形密封圈装配过程中相关密封性能参数,并通过旋转力矩实验验证了密封圈性能评估有限元模拟技术的有效性。其次,基于唇形密封圈物理模型并结合设计工程师对产品性能评估的需求,提出了基于物理模型的仿真流程定制技术,并采用Visual Basic语言,结合Femap API,开发了唇形密封圈密封性能评估软件。最后,通过实例验证了该软件的有效性与通用性,结合CAD (computer aided design,计算机辅助设计)参数化技术,在灵敏度分析的基础上以提高唇形密封圈静密封性能为目标进行结构优化,最终达到提高产品密封性能与密封圈性能评估效率的目的。
In order to solve the problem of the complexity and inefficiency of lip seal performance evaluation for lip seal,the rapid simulation process customization technology of static sealing performance of lip seal based on physical model of lip seal which was referred to the physical model and combined with Femap & NX Nastran platform was proposed.First of all,based on MooneyRivilin constitutive relationship of rubber material,an axisymmetric numerical model of lip seal was established by using FEA(finite element analysis)software,the convergence control techniques was applied to the nonlinear problem of the model,and the good convergence was obtained.At the same time,the relevant sealing performance parameters during the assembly of the lip seal was verified by finite element simulation,and the effectiveness of the sealing performance evaluation was verified by the rotational torque experiment.Then,the simulation process customization technology based on the physical model of the lip seal and considering the design engineers' requirements for product performance evaluation was developed by using Visual Basic language and Femap API.Next,an example was performed to verify the effectiveness and universality of the performance simulation,and the structure optimization was carried on by using the CAD(computer aided design)parameterization technology to improve the static sealing performance of lip seal on the basis of sensitivity analysis.The sealing performance of lip seal and evaluation efficiency of the product are improved finally.
