Viscosity-radius expression was deduced based on the measured viscosity-temperature relationship of YLA-N32 hydraulic oil. Taking account of the effect of pressure difference and inertia force on the oil film, respectively, the analytic solutions for pressure and torque with variable viscosity were derived by using the deduced viscosity-radius expression. The results found that when the viscosity...
Many robotic systems, like surgical robots, robotic hands, and exoskeleton robots, use cable passing through conduits to actuate remote instruments. Cable actuation simplifies the design and allows the actuator to be located at a convenient location, away from the end effector. However, nonlinear frictions between the cable and the conduit account for major losses in tension transmission across the...
Synchro-self-shifting (SSS) clutch is used widely in the ship propulsion system, power plants and other plants. It is one of the most important parts during the system and needed to be simulated in the simulation research of power plant system. However, the mathematical model of the SSS clutch has almost never been presented in the existing published research reports. It has been shown that the transmission...
In some cases, tendon-sheath transmission systems were used to transmit power into work places through complex paths, such as the small narrow crevices possibly existed in the ruins of disasters or complex pipelines. Thus the tendon-sheath systems might work in arbitrarily curved shape. Based on the results in constant curvature, the transmission characteristics of tendon-sheath in arbitrarily curved...
