[Slide] steel ball bearing hinge stability analysis of the stability analysis method of steel are for the structure under external loads directed against the existence of conditions of deformed steel ball bearing pull, this should be studied with the deformation of deformation occurs when the corresponding structure or component instability. Was between structural deformation and nonlinear relationship between load and stable computing non-linear geometry problems, using a second-order analysis. Stability calculation is determined whether or buckling load ultimate load bearing capacity of the structure can be regarded as stable or component calculated. [Slide] DHQZ ball bearing hinge damping steel ball bearing design parameters: 1. Design of vertical bearing capacity of 0.8-80MN. 2. The level of design capacity was greater than or equal to the design of vertical bearing capacity of 20%. 3. Design angle is greater than or equal to 0.02rad. 4. Design of sliding friction coefficient of less than or equal to 0.03. 5. Design damping ratio is greater than or equal to 15%. [Slide] damping spherical ball joints bearing steel bearing Main Features 1. Supports the use of weathering properties and good corrosion resistance to seawater Q355NH 10MnPNbRE weathering steel and cast steel. 2. The outer layer of "metal spray paint heavy anti-Ac + aluminum outer shield layer +" multiple protection system, the metal coating is greater than the total thick film 400um. 3. Turn the spherical friction surface using a combination of stainless steel and Teflon . 4. The use of damping and seismic measures, with strong damping and seismic effects. Seismic structure of horizontal shear structure means Guangrun pullout steel ball bearings, namely the shear pin block with a combination of shock absorption, and its working principle is that when there is a strong level of force generated when the bearing plate extrusion and Ceiling shear block connection, when the pressing force exceeds the yield strength of the shear pin and the bolt, both the shearing means is an effect. [Slide] ball bearing hinge bolted: riveting form, in construction, is now rarely used, and poor performance are usually shear bolts can be used in the secondary structure of the site, high-strength bolts, using increasingly widespread and commonly 8.8s 1 0.9s two intensity levels, according to the mechanical characteristics of sub-type pressure and friction type. Both calculation methods, high-strength bolts minimum specifications m12, commonly m16 ~ m30, oversized bolt unstable performance specifications of universal uplift steel spherical bearings, the design should be used with caution. Self-tapping screws for secondary connection between the plate and the thin-walled steel. Abroad in low-rise apartments in wallboard, also used to connect the main structures. [Slide] ball bearing hinge support research and development force of the 1990s, China's Ministry of Railways CRCC are, based on years of research experience pot bearing on the reference information abroad, bearing against the dynamometer [ slide ball bearing hinge] basic requirements, combined with the specific application requirements of railway bridge, take advantage of a steel pot rubber bearing plate isotropic compression, rubber various parts of uniform pressure, positive pressure and the rubber ring on the side of the basin is basically the same pressure The characteristics, in the rubber bearing plate in the oil chamber to measure the use of hydraulic bearing reaction force, complete our pot rubber bearing dynamometer research and development, and applied directly to the real bridge, and achieved good effect. Pot rubber bearing force, not only apply to the railway bridge, also applies to highways and municipal engineering. [Slide] ball bearing hinge rubber basin study pullout force bearing steel ball bearings, successfully resolved within the rubber molding process chamber oil bearing plate, bearing dynamometer dynamometer hydraulic system design and support seal performance and test methods seat. [Slide] The ball bearing hinge bearing dynamometer calibration and field testing, surface use oil cavity formation in the rubber bearing plate, the injection of special hydraulic oil, change oil bearing actual reaction reaction force method is reasonable effective. Force measurement accuracy of such holder can reach 10% bearing Capacity.
