| Properties of metal rubber seal is metal rubber technology is an importantresearch direction, metal rubber seal with a working temperature range, goodelasticity, strong bearing capacity, corrosion resistance, radiation and aging is noteasy, and many other features in the aviation aerospace, defense and armamentspecial working environment has a very broad application prospects. However,due to the special rubber seals metal structure, a unique preparation process aswell as the development of special test equipment exists in many of the keytechnologies to be solved, has become a bottleneck restricting its engineeringapplications, therefore, the papers prepared for metal rubber seals technologyresearch and development work dedicated test bench has important theoreticalsignificance and application value.Aerospace and defense against weapons of different temperature, pressuresealed environment of the specific requirements for the preparation of metalrubber seals research, we propose a method for preparing a metal outer foreskinrubber seals new approach to design and prepare different structural forms metalrubber seals. With stainless steel wire as raw material processing of metal rubberelastomers, through different processing techniques, prepared with differentstructural dimensions of PTFE-encapsulated metal rubber seals, PTFE semi-clad"C" shaped metal rubber seal fittings, stainless steel clad metal rubber seals andhigh-temperature alloy coated metal rubber seals.Carried out based on different ambient temperatures and relative density ofmetal rubber seal hysteresis experimental study of temperature, relative densityof metal rubber seals hysteresis effects in a metal rubber seals energy dissipationcoefficient, mean stiffness coefficient variation. Through the analysis of the testresults to derive temperature environment of metal rubber seal force anddisplacement formula, and the formula is a numerical exampleAccording to Air Force research projects proposed pre-assembly of thetechnical parameters and test the functional requirements to determine the metalrubber seal dedicated test rig’s overall plan, cell-based modular design concept,the completion of the overall structure of the test stand design andcomputer-aided measurement and control systems of each unit designed to solve the leakage detection, dynamic seal precision control and processing in thepreparation of technical problems, successfully prepared to meet the hightemperature, high pressure, radial static and dynamic seals and seal performancetest requirements of metal rubber seal dedicated test rig for metal Experimentalstudy on rubber seals and application of the foundation. |
