Study On The Reliability Of The Mounting Plate Of Height Control Value

For the mounting plate of height control value, the weakest area is the preload joint surface. It's impossible to test the dynamic stress of preload joint surface directly by current technology. Within this article, the method of defining the suitable parameters for the finite element contact model and the finite element model of the altitude valve's mounting plate were built. By the harmonic response analysis, the dynamic nature and the transitive relation between the preload joint surface and the testing point were collected. From the finite element's result and the test data, the transitive relation was corrected, then the calculated dynamic data of the preload joint surface can be generated and the figure life of the mounting plate of height control value will be assessed finally.
