钛合金阀门抗冲击性能分析

Impact Resistance Analysis of Titanium Alloy Valve

摘要:

本文针对船用钛合金阀门，根据其设备等级和安装位置，按照GJB 1060.1-91《舰船环境条件要求机械环境》规定参数进行抗冲击性能分析。本文以角型截止阀为例，采用响应谱分析方法对其模态和抗冲击性能进行分析，得到钛合金阀门的模态频率和三向应力，采用试验方式对其抗冲击性能进行验证。同时针对同一结构的角型截止阀，采用不同类型的常用材质进行抗冲击分析，得到不同材质对阀门抗冲击性能的影响。结果表明：1）响应谱数值分析方法可为阀门的抗冲击性能提供有效的参考；2）模型受冲击作用时，应力分布受结构影响较大，受材料影响较小，最大应力值受材料影响较大；3）相同结构不同材质的阀门抗冲击性能由高到低依次为TA31、TA2、QAl10-5-5和06Cr19Ni10。本文采用模拟分析和试验验证的方式对阀门的抗冲击性能进行分析研究，为该类阀门的工程化设计提供参考。

Abstract:

The impact resistance performance of Marine titanium alloy valves was analyzed in this paper, according to the equipment grade, installation location and the parameters specified in GJB 1060.1-91 "requirements for mechanical environment of ship environmental conditions".Taking angle globe valve as an example, the modal and impact resistance performance was analyzed with response spectrum analysis method, and the modal frequency and three-way stress of titanium alloy valve was obtained. The impact resistance performance was verified by test method. After that, different types of common materials were analyzed with the same angle globe valve, and the impact resistance was obtained. The results show that the response spectrum analysis method could provide an effective reference for the impact performance of the valve. In addition, the stress distribution is greatly affected by the structure, little by the material, and the maximum stress value is greatly affected by the material, while the model is impacted. Finally, the impact resistance of valves with the same construction was from high to low for TA31, TA2, QAl10-5-5 and 06Cr19Ni10.In this paper, the impact resistance of valve was analyzed and studied by means of simulation analysis and test method, which provided a reference for the engineering design of this kind of valve.
