Analysis and Study of Deformation Accident of a Test Bench with Expansion Joint
The design of high-temperature and high-pressure piping for a model combustion chamber pressure molding test stand was developed,in view of the deformation of expansion joints during the pressure test of a certain type of combustor pressure modeling test-bed pipeline,the cause analysis is carried out according to the actual deformation situation on the spot,and the optimization and improvement scheme of expansion joint and test-bed is proposed,the feasibility of the scheme is demonstrated by finite element analysis.On-site adjustment is carried out according to the optimized improvement scheme,and the high temperature and high pressure joint adjustment test is carried out to verify the feasibility of the optimized improvement scheme.
