Problems solved by technology
However, in the prior art, the ultra-high pressure seal of the moving parts on the autoclave is a contact seal, and the axial friction force and friction torque generated by the contact seal are difficult to remove from the measurement data, and it is impossible to ensure that the loading force is always perpendicular to the surface of the test piece. Affect the measurement accuracy of test force and loading force

The invention discloses a loading force direction adaptive adjusting device and a testing platform thereof. The adaptive adjusting device mainly comprises a test bed operation cabinet, a frictional wear test bed main device and loading and measuring components, wherein a test bed can simulate a deep-sea ultrahigh pressure (0-11000m deep) environment, and is used for synchronously performing dynamic corrosion tests and friction wear tests; the loading device has a sealing and cooling integrated design by adopting non-contact combined sealing, and has the characteristics of exact loading force transferring and excellent cooling; the loading component and the measuring component are relatively independent, so that the interference of additional friction and friction torque on measurement data can be effectively isolated, and exact transfer and accurate measurement of the loading force inside and outside a pressure kettle can be realized; the pressure kettle adopts quick-opening hoop structure connection, and is convenient to detach and reliable to connect; and the test bed is positioned by adopting fit of a positioning optical axis, a supporting sleeve and a stepped bore, and has the advantages of high positioning accuracy, low processing and manufacturing cost and compact structure.
Description
technical field [0001] The invention belongs to the field of friction and wear test bench design, and in particular relates to a loading force direction self-adaptive adjustment device, a pressure kettle and a test platform. Background technique [0002] The ocean is the frontier field of high-tech development, and the development of the ocean is highly dependent on engineering technology. Since the 1990s, my country has begun to attach importance to the development of high-tech in marine development. In 1996, marine high technology was listed as the eighth field of the "National High Technology Research and Development Plan" (863 Plan); in 2011, the "National "Twelfth Five-Year Plan" Science and Technology Development Plan" listed high-end marine engineering equipment as a vigorously cultivated field. Strategic emerging industries for development and development, developing key technologies and equipment for offshore oil and gas exploration and development, deep-sea transp...
