船用燃气轮机动力涡轮支架光弹应力测试分析

Photoelastic Stress Measurement and Analysis of Marine Gas Turbine Power Turbine Support

本文利用光弹性原理,对某型船用燃气轮机动力涡轮后支架进行了应力测试分析,给出了该支架的等倾线和等差线,并在此基础上计算了该支架某截面的应力分布。

This paper describes the stress measurement and analysis of a marine gas turbine power turbine rear support by use of photoelasticity theory,presents the isoclinic lines and equidifference lines and on this basis calculates the stress distribution on the said support section.
