Априорное определение тягового сопротивления глубокорыхлителя методами теории размерностей и подобия

Априорное определение тягового сопротивления глубокорыхлителя методами теории размерностей и подобия

Abstract

Methods of the similarity theory in relation to justification of parameters and operating modes of machines for deep tillage are considered. The data of North Caucasian Machine-testing station testing are generalized and the dependence opening interrelation of parameters and operating modes of deep-rippers from the physicist mechanical properties of the soil are received. Graphs for defining draft of the deep-ripper in various operating conditions, to select operating modes and to calculate the parameters of the machine are plotted.

Рассмотрены методы теории подобия применительно к обоснованию параметров и режимов работы машин для глубокой обработки почвы. Обобщены данные испытаний глубокорыхлителей на Сев. Кав. МИС и получена зависимость, раскрывающая взаимосвязь параметров и режимов работы глубокорыхлителей с физико-механическими свойствами почвы. С помощью полученной зависимости построены графики, позволяющие определять тяговое сопротивление глубокорыхлителей в различных условиях работы, выбрать режимы функционирования и рассчитать параметры машины.
