Description
(54) СТЕНД дл ИЗМЕРЕНИЯ УРОВНЯ ШУМА ТРУЩИХСЯ ОБРАЗЦОВ(54) THE STAND FOR MEASURING THE NOISE LEVEL OF THE SLAMING SAMPLES
щее устройство может быть выполнено в виде рычажно-механической, пневмогидравлической или электромеханической системы. Перед измерением производ т установку образцов 3, 4 на плите 6 и иагружающем устройстве. 14 на требуемом рассто нии R от Оси стержи 5. Одновремеиио производ т установку источника I1 света и фотоэлемента 12. Акустический преобразователь 9 размещают на определенном рассто нии от зоны контакта, завис щем от его чувствительности.The device can be made in the form of a lever-mechanical, pneumohydraulic or electromechanical system. Before the measurement, samples 3, 4 are mounted on the plate 6 and the loading device. 14 at the required distance R from the axis of the rod 5. Simultaneously, light source I1 and photocell 12 are installed. Acoustic transducer 9 is placed at a certain distance from the contact zone depending on its sensitivity.
Затем эакручиваЬт стержень 5 вместе с плитой 6 на требуемый угол. При отпускании стержн 5 плита 6 вместе с образцол 3 начинает совершать колебани с периодом, завис щим от угла закручивани и момента инерции колеблющихс элементов. Одновременно с отпусканием стержн начинают измерени уровн шума и скорости взаимного скольжени образцов.Then pull out the rod 5 together with the plate 6 to the required angle. When releasing the rod 5, the plate 6 together with the sample 3 begins to oscillate with a period depending on the twist angle and the moment of inertia of the oscillating elements. Simultaneously with the release of the rod, begin to measure the noise level and the rate of mutual slip of the samples.
