Effect of mounting and fluid parameters on dynamic damping ...
A mathematical model describing the dynamic damping characteristics (DDC) of a high-speed rail hydraulic damper is built and experimentally validated, followed parameter effect simulation on DDC of the damper is conducted by using the model. Simulation results show that the change of rubber attachment stiffness and entrapped air ratio would have apparent …

On damping parameters of Levenberg-Marquardt algorithm for …
The Levenberg-Marquardt (LM) algorithm is a widely used method for solving problems related to nonlinear least squares. The method depends on a nonlinear parameter μ known as self-scaling parameter that affects the performance of the algorithm. In this paper we examine the effect of various choice of parameters and of relaxing the line search.
A second-order numerical method for Landau-Lifshitz-Gilbert equation ...
The LLG equation is a vectorial and nonlinear system with the fixed length of magnetization in a point-wise sense. Significant efforts have been devoted to design efficient and stable numerical methods for micromagnetics simulations; see [7], [14], [20] for reviews and references therein. Among the existing numerical works, semi-implicit schemes have been very …

The main function of the vent valve is to release part of the air at the outlet of the axial compressor to prevent engine surges. The damping parameters have an important effect on the opening and closing characteristics of the vent valve. The control characteristics of each component were obtained by finite element analysis and testing. The overall model of a two …
