Many applications in beam physics, particularly those concerning transverse beam dynamics, call for an approximate computation of the transverse electric field produced by the charge distribution of the beam, namely the field components in the plane perpendicular to the beam motion. Mathematically, this approximation becomes exact in the limit of an infinitely long charge distribution that is a...

Effective repair of worn big gear has large influence on ensuring safety production and enhancing economic benefits. A kind of intelligent repair welding method was put forward mainly aimed at the big gear restriction conditions of high production cost, long production cycle and high-intensity artificial repair welding work. Big gear repair welding mechanism was designed in this paper. The work...

To solve the design problem of non-circular gears with cusp pitch curves, this paper proposed a new variable-involute and incomplete variable-cycloid composite tooth profile (VIIVC-CTF), deduced VIIVC-CTF mathematical model, constructed conjugate gear model based on envelope method. The software curve was developed MATLAB. variation law rolling radius an cycloid its characteristics such as pres...

This study explores the elastohydrodynamic lubrication (EHL) between contacting tooth flanks of a worm gear with nonconjugate meshing action. The contact is characterized by slender-like elliptical shape and high sliding. geometry conditions for considered were obtained using analysis. Based on that, complete area was analyzed validated numerical EHL model considering non-Newtonian, thermal, tr...

The gearbox is a complex system component and its core is the gear shafting. The gear system output the power to the drive shaft with speed changing through the engine. In the actual work, because of the installing error, load distortion and shock load situation, the correct meshing condition of gears was destroyed. 3D model of transmission gear was firstly built up by using SolidWorks software...

This paper presents design and analysis of torque and flux density in perpendicular magnetic gear with different magnetic materials, dimensions and air gap. The results were compared to each other. This type of gear offers both high gear ratio and high torque. Moreover the low speed side is connected to prime mover and high speed side is connected to load after analysis, which is sui table for ...

The paper aims at the complex situation of the tractor field operation and adopts the gear shift rule of two parameters to control the six gear shift of the tractor. Using the artificial neural network chip the model number of which is ZISC036 and the computer on slice the model number of which is PIC17C42 establishes the controller of the radial basis function artificial neural network-RBFANN....

In this paper, numerical simulations are used to study the turbulent wind noise reduction effect of microphone windscreens with varying shapes and flow resistivities. Typical windscreen shapes consisting of circular, elliptical, and rectangular cylinders are investigated. A turbulent environment is generated by placing a solid circular cylinder upstream of the microphone. An immersed-boundary m...

Solutions of stress intensity factors for external and internal unpressurized and pressurized surface cracks in internally pressurized thick-walled reactor pressure vessels are determined directly by a three-dimensional displacement-hybrid finite element method. The finite element method is based on a rigorous modified variational principle of the total potential energy, with arbitrary element ...

We present an implementation of the [Marschner et al. 2003] model for importance sampling light reflected from hair. The implementation makes use of a version of Adaptive Importance Sampling (AIS), specialized to fit easily sampled distributions to BCSDFs. Our model is novel among importance sampling implementations in that it includes all the features of Marschner such as eccentricity for elli...
