... and side contact between asperities is established by statistical theory. The simulation results of the model show that the dimensionless tangential contact stiffness of joint is always lower than that of the GZQ model under the condition of the same dimensionless average distance of contact surfaces and P...

... characterization that must be considered for reliable operation. Finally, it examines in detail the geometrical configurations, load-bearing capacity, dynamic behavior, and stability connected with stiffness and damping.

..., 2014. Assoc. Editor: Zhong Min Jin. 08 12 2013 13 07 2014 In order to determine that the stiffness varies between different joint types, an indentation test was performed on fresh equine articular cartilage surfaces from the fetlock, carpal, and stifle joints. The results...

.... This assumption implies a homogenous magnetic field. The fundamental expression for the magnetic field is given by the Gauss law (4) ∇ B = 0 The stiffness and damping properties of a journal bearing can be treated in a manner analogous to a spring and viscous damper from simple vibration...

... motion and then no damping exists. Under this condition, the contact body is only supported by the elastic restoring force. By analyzing the changes of steady state mutual approach with load in Fig. 5 , the variations of stiffness with load can be analyzed qualitatively. Figure 5 shows...

..., revolute joints have a major impact on the dynamic behavior of the system into which they are built. Two main characteristics of these elements are their stiffness and their clearance. Both of them change as the wear between the joint’s pin and the rod hole increases during operation. In order to consider...

...Hiroyuki Ohta; Keisuke Tanaka This article deals with the vertical stiffnesses of preloaded linear guideway type ball bearings (linear bearings) incorporating the flexibility of the carriage and rail. First the vertical stiffnesses of light and medium preloaded linear bearings were measured...

... the performance of the GFB structure. This paper presents experiments conducted to estimate the structural stiffness of a test GFB for increasing shaft temperatures. A 38.17 mm inner diameter GFB is mounted on a nonrotating hollow shaft affixed to a rigid structure. A cartridge heater inserted into the shaft...

... ( infinite speed number) follows. The bearing ultimate load and stiffness coefficients are derived from simple algebraic equations for the gas film pressures at the equilibrium journal position and due to small amplitude journal motions, respectively. GFBs without a clearance or with assembly interference...
