Baseband transmission system have an irreplaceable role in the digital transmission system, its scope of application to penetrate into the network communication satellite communications, monitoring control, mobile communications, digital television, digital telephone life, science and technology in all aspects with the development of technology, thus increasingly becoming a key technology in the digital...
A non-iterative design method on an approximate equal velocity ratio transmission mechanism is presented. The mathematical principle is that a compound function produced by two basic functions, let its one order differential is equal to a constant at special point, and then two to three order derivatives of the compound function are all zeroes, thus two algebraic equations are got, their solutions...
As a new kind of cylindrical gear, the in volute arch cylindrical gear has preferable transmission characteristics, but its main geometry parameters have no unified standard. In this paper, the ideal geometry parameters of in volute arch cylindrical gear are proposed and its tooth surface equation and meshing line equation are discussed. For verification, the computer graphics is introduced to show...
In this paper, we extend the modal formulation to characterize the transmission characteristics of a circular pipe with two open ends. Our interest in this problem stems from the possibility of using an open pipe as a transmission medium to propagate waves through an opaque wall at radar frequencies. We begin this study by developing an approximate solution for the transmitted field through a circular...
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...
