Известные устройства дл определени напр жений, возникающих в прозрачном материале при его нагружении. содержащие механизм нагружени и объектив, наведенный на экран через исследуемый образец , обладают низкой точностью измерени , так как при наблюдении картины напр жений неизвестна действительна величина нагрузки , приложенна к исследуемому образцу. Необходимость определенл приложенной к образцу нагрузки по шкале отдельного прибора, нередко расположенного на значительном рассто нии от проекционного экрана, создает неудобства в работе и приводит к по влению допоотнительных ощибок измерени .The known devices for determining stresses arising in a transparent material when it is loaded. containing the loading mechanism and the lens induced on the screen through the sample under test have a low measurement accuracy, since when observing the pattern of stresses, the actual magnitude of the load applied to the sample under test is unknown. The need to determine the load applied to the sample on the scale of a separate instrument, often located at a considerable distance from the projection screen, creates inconvenience in the work and leads to the appearance of additional measuring errors.
В предлагаемом устройстве дл иовьипени нагл дности изображени и точности измерени применена прозрачна с изображением стрелки шкала, котора при помощи нерест жимой нити св зана с кареткой нагрузочного механизма и поворачиваетс на угол, пропорциональный величине, приложенной к образцу нагрузки. В результате этого на проекционном экране одновременно с картинами напр жени можно наблюдать действительную величину приложенной нагрузки.In the proposed device, in order to achieve image consistency and measurement accuracy, a transparent scale with an arrow is used, which, by means of an spawn, is connected with the carriage of the loading mechanism and is rotated by an angle proportional to the value applied to the load sample. As a result of this, the actual value of the applied load can be observed on the projection screen simultaneously with the voltage patterns.
На чертеже изображено предлагаемое устройство.The drawing shows the proposed device.
Исследуемый образец /из прозрачного материала закрепл етс в раме 2 при помощи захватов . Захват 4 св зан при помощи т ги 5. с нагрузочным механизмом, состо щим из силовой пружины 6 и руко тки 7. Пропорционально действующей на образец нагрузке будет iieремещатьс опорна щайба 8, котора при помощи нераст жимой нити 9, переброщенной через шкив 10, св зана с прозрачной щкалой // с изображением стрелки.. Шкала // расположена за исследуемым образцом и поворачиваетс на угол, соответствующий величине приложенной нагрузки. Посто нное нат жение нити 9 обеспечивает груThe test sample / transparent material is fixed in the frame 2 by means of grippers. The gripper 4 is connected by means of a gig 5. to a load mechanism consisting of a power spring 6 and a handle 7. A load plate 8 will displace in proportion to the load on the sample iie, which with the help of an inextensible yarn 9, rebased through the pulley 10, is connected with transparent arrow // with the image of an arrow. The scale // is located behind the sample under study and rotates through an angle corresponding to the value of the applied load. The constant tension of the thread 9 provides the load
