Задача №14.14

Условие

Написать уравнение движения поршня нецентрального кривошипно-ползунного механизма. Расстояние от оси вращения кривошипа до направляющей линейки h, длина кривошипа r, длина шатуна l; ось Cx направлена по направляющей ползуна. Начало отсчета расстояний — в крайнем правом положении ползуна; l/r=λ, h/r=k, φ=ω0t.

Решение




Предыдущая задача №13
Найти закон движения стержня, если диаметр эксцентрика d=2r, а ось вращения O находится от оси диска C на расстоянии OC=a, ось Ox направлена по стержню, начало отсчета — на оси вращения, a/r=λ.
Следующая задача №15
Кулак, равномерно вращаясь вокруг оси O, создает равномерное возвратно-поступательное движение стержня AB. Время одного полного оборота кулака 8 с, уравнения движения стержня в течение этого времени имеют вид (x — в сантиметрах, t — в секундах)
x = 30 + 5t, 0 ≤ t ≤ 4,
x = 70 - 5t, 4 ≤ t ≤ 8.
Определить уравнения контура кулака и построить график движения стержня.
