Acoustics and Vibration of Mechanical Structures—AVMS-2017

Complementary to our online or face to face live training sessions we propose to directly purchase our training slides in PDF format, and order a customized Technical Talk to discuss some specific points privately with our trainers. The slides do not include animations and sound files which are only accessible during our live training. Each sl Each slide package can be purchased individually, or of course several of them.

A free download of two accompanying documents is always possible: nomenclature and vocabulary and an introduction to magnetic noise and vibrations under the download tab. This part of the training covers the fundamentals of electrical machines for mechanical or vibroacoustic engineers who are not familiar with electrical engineering. Key notions such as electrical machines topologies, torque production and Pulse Width Modulation are covered. The link with electrical machines is regularly done This part of the training reviews the physical generation process of magnetic noise and vibrations.

General formula of magnetic force harmonics in Permanent Magnet Synchronous Machines and Induction Machines are provided by combining permeance, magnetomotive force, and flux Noise mitigation techniques cover magnetic, control and structural design parameters, but most of the course deals with electromagnetic design modifications as it is the most efficient way to control magnetic noise This part discusses the different ways to include the assessment of magnetic noise and vibrations in a virtual prototyping workflow of e-machines in terms of accuracy, speed and robustness.

Different modelling approaches are reviewed, and numerical challenges of CAE-based calculations are discussed. Algorithms to speed up calculations like vibration This part of the training demonstrates how to carry noise and vibration measurements to quickly troubleshoot issues. Some experimental spectrogram coming from EV HEV applications are reviewed in detail and interpreted using theory.

The sensation felt by our ears is called sound. It is a form of energy which makes us hear. We hear several sounds around us in our everyday life. A wave is a vibratory disturbance in a medium which carries energy from one point to another without there being a direct contact between the two points. We can say that a wave is produced by the vibrations of the particles of the medium through which it passes. There are two types of waves: Longitudinal waves and Transverse waves. Medium can be solid, liquid or gases.

Acoustics and Vibration of Mechanical Structures—AVMS-2017

In physics, sound is produced in the form of a pressure wave. When an object vibrates, it causes the surrounding air molecules to vibrate, initiating a chain reaction of sound wave vibrations throughout the medium. There are many different types of sound including, audible, inaudible, unpleasant, pleasant, soft, loud, noise and music. Other sounds, such as a dog whistle, are inaudible to the human ear. This is because dog whistles produce sound waves that are below the human hearing range of 20 Hz to 20, Hz.

In physics , sound is a vibration that propagates as an acoustic wave , through a transmission medium such as a gas, liquid or solid. In human physiology and psychology , sound is the reception of such waves and their perception by the brain. Different animal species have varying hearing ranges. Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gases, liquids, and solids including vibration , sound, ultrasound, and infrasound. A scientist who works in the field of acoustics is an acoustician , while someone working in the field of acoustical engineering may be called an acoustical engineer.

 Где оно? - не отставал Беккер. - Понятия не имею.  - Парень хмыкнул.  - Меган все пыталась его кому-нибудь сплавить. - Она хотела его продать. - Не волнуйся, приятель, ей это не удалось.

АНБ было единственной разведывательной организацией США, освобожденной от обязанности отчитываться перед федеральным правительством. Стратмор нередко пользовался этой привилегией: он предпочитал творить свое волшебство в уединении. - Коммандер, - все же возразила она, - это слишком крупная неприятность, и с ней не стоит оставаться наедине. Вам следовало бы привлечь кого-то. - Сьюзан, появление Цифровой крепости влечет за собой очень серьезные последствия для всего будущего нашего агентства. Я не намерен информировать президента за спиной директора. У нас возник кризис, и я пытаюсь с ним справиться.
