基于ANSYS的某型飞机液压管路应力测试

Stress Test of Hydraulic Tubing in Aircraft Based on ANSYS

为了优化液压管路应力测试,减少测点数量,提高测试准确度,提出在应力测试前用ANSYS对管路进行受力分析,试验后用试验数据进行模型修正。通过对管路进行三维建模,将模型导入ANSYS,分析管路振动时应力分布,根据受力情况确定传意器的安装位置。后将测得的数据修正模型参数,通过模型计算最大应力。通过ANSYS优化应力测试,减少了传感器布置的数量,提高了测试的准确度。

In order to minimize the quantity of strain gauges and improve the accuracy in the stress test of hydraulic tubing.Stress analysis based on ANSYS before the test is proposed in this paper. The CATIA mockups of the hydraulic tubing are imported to ANSYS and the stress analysis is carried out by Workbench. The locations of sensors are optimized according to the calculated stress distribution. The data measured in the test is used to optimize the finite element model. The quantity of strain gauges used in the stress test can be minimized and accuracy can be improved in the field test by implementing the proposed method.
