متن کاملLateral Stability Analysis of High-Speed Railway Vehicle on Curve
A vehicle body, two bogie frames and two wheelsets for each bogie frame are used to describe the railway vehicle model. The system dynamic is modeled using a 38-DOF system including the longitudinal, lateral, vertical, roll, pitch and yaw displacements. A heuristic nonlinear creep model and the elastic rail are used to simulate the wheel-rail contact. Stable movement and the corresponding limit...
متن کاملHigh-Speed Interface Testing
1.Problem of High-Speed Interface Macro Testing Because the function of the chip is guaranteed, the high-speed function test is important. Moreover, it is an important issue in LSI test how cheaply to do this test. The high-speed function test in an internal logical circuit can be tested by using BIST methodology and the output clock of PLL with a low-speed and low-cost ATE. However, the high-s...
متن کاملExtension Robust Control of a Three-Level Converter for High-Speed Railway Tractions
In this paper, the dynamic model of a three-level neutral point clamped (NPC) converter with neutral-point voltage-balance control (NPVBC) and input power factor correction for high-speed railway tractions is derived. And accordingly, a feedback controller is designed to meet the given voltage regulation control specifications. As the variation of converter parameters occurs, a compensation sig...
متن کاملGroundwater Level Changes Due to Extreme Weather—An Evaluation Tool for Sustainable Water Management
In the past decade, extreme and exceptional droughts have significantly impacted many economic sectors in the US, especially in California, Oklahoma, and Texas. The record drought of 2011–2014 affected almost 90% of Texas areas and 95% of Oklahoma state areas. In 2011 alone, around $1.6 billion in agricultural production were lost as a result of drought in Oklahoma, and $7.6 billion in Texas. T...
