угловая частота
Скорость изменения фазы синусоидального электрического тока, равная частоте синусоидального электрического тока, умноженной на 2π.
Примечание — Аналогично определяют угловые частоты синусоидальных электрического напряжения, электродвижущей силы, магнитного потока и т. д.

angular frequency
pulsatance
ω
product of the frequency of a sinusoidal quantity and the factor 2π
NOTE – For the quantity Am cos (ω t + θ0), the angular frequency is ω.
[IEV number 101-14-36 ]FR
pulsation
produit de la fréquence d'une grandeur sinusoïdale par le facteur 2π
NOTE – Pour la grandeur Am cos (ω t + θ0), la pulsation est ω.
[IEV number 101-14-36 ]Практика остановила свой выбор на синусоидальных колебаниях переменных электрических величин. В дальнейшем, говоря о токе, э. д. с., напряжении и магнитном потоке, мы будем считать их изменяющимися по закону синуса.
Фиг. 130. Вращение вектора вокруг оси
Пусть мы имеем вектор ОА (фиr. 130), выражающий в масштабе какую-либо переменную синусоидальную величину, например ток. Будем вращать с постоянной скоростью вектор вокруг точки О против часовой стрелки. Конец вектора будет описывать окружность, а угол, на который поворачивается вектор, будет меняться с течением времени.
Угловая скорость или угловая частота ω (омега) вращения равна углу поворота вектора в единицу времени: ω=α/t, откуда α=ωt.
Часто вместо градуса пользуются другой единицей измерения угла – радианом. Радианом называется угол, дуга которого равна радиусу. Если длина окружности С=2πR, то она содержит 2πR/R=2π радиан.
За один оборот радиус-вектор ОА будет иметь один период вращения продолжительностью Т секунд.
Угловая частота в этом случае выразится: ω=α/t=2π/T рад/сек.
Так как 1/Т=f, то ω=2πf рад/сек.

Фиг. 130. Вращение вектора вокруг оси
Пусть мы имеем вектор ОА (фиr. 130), выражающий в масштабе какую-либо переменную синусоидальную величину, например ток. Будем вращать с постоянной скоростью вектор вокруг точки О против часовой стрелки. Конец вектора будет описывать окружность, а угол, на который поворачивается вектор, будет меняться с течением времени.
Угловая скорость или угловая частота ω (омега) вращения равна углу поворота вектора в единицу времени: ω=α/t, откуда α=ωt.
Часто вместо градуса пользуются другой единицей измерения угла – радианом. Радианом называется угол, дуга которого равна радиусу. Если длина окружности С=2πR, то она содержит 2πR/R=2π радиан.
За один оборот радиус-вектор ОА будет иметь один период вращения продолжительностью Т секунд.
Угловая частота в этом случае выразится: ω=α/t=2π/T рад/сек.
Так как 1/Т=f, то ω=2πf рад/сек.

угловая частота гармонических колебаний (вибрации)
угловая частота
Ндп. циклическая частота
круговая частота
Производная по времени от фазы гармонических колебаний (вибрации), равная частоте, умноженной на 2п (см. термин гармонические колебания (вибрация)).
Пояснения
1)Некоторые величины и зависимости, характеризующие вибрацию, могут относиться к перемещению, скорости, ускорению, силе и другим колеблющимся величинам. Если возможны различные толкования, следует дать соответствующее уточнение, например «размах виброперемещения», «амплитуда силы», «амплитудно-частотная характеристика виброускорения».
2)Термины и определения для близких понятий, различающиеся лишь отдельными словами, совмещены, причем слова, которые отличают второе понятие, заключены в скобки. Для получения первого термина и его определения опускаются слова, записанные в скобках. Для получения второго термина и его определения проводится замена соответствующих слов словами, записанными в скобках. Например, термин периодические колебания (вибрация) содержит два термина с определениями:
периодические колебания - колебания, при которых каждое значение колеблющейся величины повторяется через равные интервалы времени;
периодическая вибрация - вибрация, при которой каждое значение колеблющейся величины, характеризующей вибрацию, повторяется через равные интервалы времени.
