摘要
选用合适的计算方法可以为管路补偿器的位移疲劳寿命和耐久振动寿命计算提供计算依据。采用有限元法和工程方法分别计算管路补偿器在轴向、拉伸、径向摆动下的位移疲劳寿命及耐久振动寿命,并通过试验进行对比验证分析。结果表明:有限元法对于补偿位移疲劳寿命的计算精度优于工程计算法,有限元法可以给出确定的振动应力分布,并能预测出耐久振动寿命时间。
The suitable selection of calculation method can provide the calculation basis for displacement fatigue life and durability vibration life of pipeline compensator.The finite element analysis and engineering calculation methods are used respectively to calculate the displacement fatigue life and durability vibration life of pipeline compensator at axial direction,pulling direction and radial wobble direction,and conducted with comparison and verification analysis by experiment.The results show that,the calculation precision of finite element analysis method is superior to that of engineering calculation method,the finite element analysis method can give the definite vibration stress distribution,and predict the durability vibration life.
