Работа содержит описание стенда, методику измерения и результаты некоторых измерений. На стенде применили механический привод с плавной регуляцией скорости деформации в пределах 0 - ок. 1,5·10⁻³ М·с⁻¹ и тензодатчики для измерения силы и деформации, зависимость которых вычерчивал регистратор х, у. На основе анализа диаграмм, полученных в результате погружения металлического плунжера в структуру яблока, можно выделить линейный характер зависимости. Измерение основных механических свойств указывает на отчетливую их дифференциацию во время сбора и хранения.

The position for the purpose of measuring mechanical properties of apples was designed and made. This paper contains a description of the stand, method of measurement, and the results of some measurements. Mechanical power with stepless control of the speed of deformation in the range from 0 to 1,5·10⁻³ m·s⁻¹ was used. Strain gauges were used to measure force and deformation, the interdependence of which was shown in the recorder x, y. On the basis of on analysis of diagrams obtained as a result of plunger penetration into the structure of the apple, the linear character of the dependence may be determined. Measurements of the basic mechanical properties indicate their differentiation in the period of harvest and storage.
