This example illustrates how to perform eigenfrequency and static analyses of a ladder frame structure for a light truck. Important modeling strategies are described. For example, how to convert a solid geometry to a shell model, how to make different types of connections, and how to ... En savoir plus
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 ... En savoir plus
The dynamic response of a human body in any vibration environment can be predicted using this biomechanical model. In the automobile industry for instance, this model can be used in ride quality simulation and designing vibration isolators such as seats. In this example, a ... En savoir plus
In this verification example, forced random vibrations of a simply-supported deep beam are studied. The beam is loaded by a distributed force with a uniform power spectral density (PSD). The output PSD is computed for the displacement and bending stress response. The computed values are ... En savoir plus
This is a model of a simple photoacoustic (or optoacoustic) resonator. A pulsating laser heats a gas causing expansion and contraction and thus creates pressure waves. Such devices are used as sensors for measuring material parameters of the gas inside the resonator. The resonance ... En savoir plus
Joints between two components of a mechanical system are sometimes not perfectly fitting. For the ease of assembly and to allow relative movement between the components, a small gap called clearance is provided between the joining components. The presence of clearance on joints can ...

Diesel particulate filters (DPFs) are designed to remove and filter soot (diesel particles) from the exhaust of diesel engine vehicles. The filters in such systems are typically structured with long, air-filled channels surrounded by a porous medium that retains the soot. Although the ... En savoir plus
Several mass–spring–damper models have been developed to study the response of a human body where mass, spring, and damper elements represent mass of different body parts, stiffness, and damping properties of various tissues. In this example, a lumped model of a human body having five ... En savoir plus
