摘要： The present disclosure discloses a deformation and control simulation test system for a tunnel engineering supporting structure, including a follow-up hoisting platform, actuators, a control system. It is horizontal structure. The follow-up hoisting platform reduces the friction caused by the weight of testing sample and facilitates experimental operations. Each actuator fixed on an annular box body reaction frame can move independently through a control system in form of force control or displacement control mode, and can achieve circumferential contraction loading through its gomphodont configuration. The hinged and curved design of the cushion blocks of actuators can adapt to the circumferential contraction deformation of a test sample and maintain a close fit with them during the loading process. The present disclosure provides a good solution for physical model tests on deformation and control of tunnel engineering supporting structures including uniform loading, non-uniform loading, and long-term loading conditions.

摘要： Techniques for testing a component for compatibility with a depressurization profile associated with a launch vehicle payload fairing during ascent are disclosed. A pressure of air or other gas within a pressure vessel containing the component is raised to a first value substantially higher than one atmosphere absolute pressure. The air/gas pressure within the pressure vessel is lowered, by venting into the ambient atmosphere, at a rate simulating or demonstrating margin with respect to the launch vehicle payload fairing depressurization profile. The component is inspected for damage. The component may be a panel including a honeycomb core sandwiched between two faceskins, the panel having a planar area in excess of twenty five square feet.

摘要： A method for testing the adhesion of elastic adhesives or elastic sealing materials on surfaces of components including: a) applying the adhesive/sealing material to a component surface, b) attempting by exerting a peeling force to detach the applied adhesive/sealing material from the component surface, and c) assessing the adhesion of the adhesive/sealing material on the basis of fractures caused in the adhesive/sealing material and the detachment of the adhesive/sealing material from the component surface by the exertion of the peeling force. Prior to and/or during step a), an anti-adhesion material layer is applied to at least one first part of the component surface, which causes poorer adhesion of the adhesive/sealing material to the component surface and therefore can be detached from the component surface with less peeling force than directly from the component surface.

摘要： High cycle fatigue testing is required with regard to a large number of components in order to evaluate their performance and capabilities. Typically such components are mounted such that an excitation mechanism such as through use of air jets can be utilized in order to stimulate vibration. In order to isolate a desired vibration mode generally, an isolation device is utilized. The isolation device presents an edge to a node within the component in order to inhibit vibration modes other than that of interest. Unfortunately, prior isolation elements tend to wear resulting in spurious results. By providing an isolation element within an isolation device, a fatigue test arrangement can be achieved in which both axial movement in the direction of a spring upon which the element is presented as well as lateral movement can be achieved.

摘要： A test facility is provided for testing materials under high temperature, pressure, and mechanical loads. The facility provides a physically scaled system that simulates conditions in hot sections of gas turbine engines. A test article is coated with a test material and exposed to a hot combusting flow in a test section housing. The article may be a pipe or conduit member oriented at any direction to the flow. A second cooler flow of fluid is channeled through the test article to create a sharp temperature gradient in the test article and through the test material. A liquid-cooled sleeve is disposed about the test article to create an annular channel of combusting flow over the test article. The downstream end of the second cooler flow is connected to the upstream end of the main hot flow at the combustion chamber.
