Lifetime Extension of Ingot Casting Molds

Due to high thermal loads subjected on the mold during casting process, cracks appear after a limited number of casting cycles. This article provides an overview of influence factors, as well as measures to increase the…

Shielding Effectiveness Calculations for Cabinets (1 – 30 GHz) in collaboration with HUAWEI

This paper deals with the computation of high-frequency fields which penetrate into two different cabinets with two different air-flow hole shapes. The software used for the simulations is Efield® and the two different…

Hybrid strategy to simulate millimeter-wave RADAR devices for automotive ADAS

A multiscale hybrid strategy is proposed to simulate Advanced Driver Assistance Systems (ADAS) in both Short Radar Range (SRR) and Long Radar Range (LRR). The first development stage was focusing on small sized radar…

Aero Forming - An Introduction of Collaborative Engineering

The decrease of physical prototypes and the growing power of simulation in the design process require greater control in the design chain calculation. This is the main reason for the arrival of SDM in the perimeter of…

Development of system identification technique for the control of structually flexible SMT machines

Acquiring dynamic characteristics of a system is an important issue for predicting and evaluating the system’s performance in early development stages in order to shorten the development time as well as to meet required…

RCS predictions for electrically large complex structures

Radar Cross Section (RCS) prediction of electrically large complex structures is a technical challenge. This paper presents the study carried out to examine the applicability of PAM-CEM Solutions, the simulation package…

Analysis of influence of plastic bumper on radio wave characteristics

From the standpoint of vehicle appearance, vehicle radar units should be located behind plastic bumpers. Plastic bumpers are made of dielectric material, which causes reflection, scattering, refraction, and diffraction…

Estimation of the threat of IEMI to complex electronic systems

The threat of ultra wideband (UWB) sources is interesting for military issues. This paper summarizes information concerning the voltages generated from some commercially available UWB generator systems and their…

Modeling Constellation Virtual Missions Using the Vdot Process Management Tool

The authors have identified a software tool suite that will support NASA’s Virtual Mission (VM) effort. This is accomplished by transforming a spreadsheet database of mission events, task inputs and outputs, timelines,…

Study on mechanical characteristics of lithium-polymer pouch cell battery for electric vehicle

In order to characterize deformation and failure behaviors of Lithium-Polymer pouch cell battery and its components, various mechanical tests were performed. Uniaxial tensile properties of electrodes, separator, and…
