Capacitively coupled RF discharges can operate in two distinct regimes depending on the discharge power. In the low power regime, known as the alpha regime, the electric field oscillation is responsible to heat and create electrons. In the high power regime, known as gamma regime, the ... 詳細を見る

An automotive midwoofer is modeled using the lumped parameter approach. The electrical and mechanical components are modeled using a lumped electric circuit, which is coupled to a finite element model for the acoustics using the Lumped Speaker Boundary feature. The large signal ... 詳細を見る

Usually limited to a specific region, corona discharges appear as a consistent luminosity. The attributes of steady glow corona discharges change depending on their polarity. Positive glow corona, also referred to as Hermstein's glow or ultra corona, presents a direct current (DC) aspect ... 詳細を見る

This tutorial model shows a virtual test setup of a conference speaker. The speaker system consists of a loudspeaker as well as three microphones. The model instigates the loudspeaker sound radiation, feedback, as well as the ability of the system to detect sound (speech) emitted from a ... 詳細を見る

Some positive electrode materials are known to deteriorate in overcharged lithium-ion battery cells. Predominantly, manganese containing electrode materials such as LMO and NMC can loose capacity due to manganese dissolving from the materials at overcharge. This decomposition is a ... 詳細を見る

Electromagnetic scattering simulation for an object with continuous rotational symmetry can be performed in 2D axisymmetry instead of 3D to drastically reduce computational time and resources. This model shows how to simulate arbitrary plane wave incidence in 2D axisymmetric models by ... 詳細を見る

Bearing clearances should be kept minimum to avoid non-synchronous vibration of a rotor. However, a tight clearance reduces the durability of the bearing. This example illustrates modeling of the vibration induced by nonlinear contact for different radial clearances. It is shown that ... 詳細を見る

リチウムイオン電池の負極グラファイト電極上の銅コレクターは, 過放電時に溶解することが確認されています. 溶解により集電体が不可逆的に損傷し, 溶解した銅イオンが再析出してデンドライトを形成する可能性があるため, 安全上の懸念事項となります. 電池は通常, 過放電を回避するために, セルレベルまたはパックレベルのいずれかで指定された電圧制限内で動作します. しかし, パック内では個々のセル間の電荷不均衡により, あるいはこのチュートリアルで部分的に調査するように, 単一の電池セル内の電極の局所的な不均一性により, 過放電が発生する可能性があります. ... 詳細を見る

The small strain overlay material model captures the effect of high stiffness at low strain as well as the hysteresis under cyclic loading, which is a common effect for most soils. The formulation allows stiffness degradation with an increase in shear strain, and the full recovery of ... 詳細を見る

In this application, a solution is pumped through a catalytic bed where a solute species reacts as it gets in contact with the solid catalyst. The purpose of this example is to maximize the total reaction rate for a given total pressure difference across the bed, by finding the optimal ... 詳細を見る
