  • Investigating Strength Of Materials By Application Of Mechanical Stress (AREA)

Description

Прсдметсм изобретени   вл етс  способ испытани  па контактное см тие образцов материалов (в частности металлов)...-Известные способы- испытани  прочности материалов, основанные на применении наконечников инденторов ) с полусферической торцевой поЕерхностью, внедр емых ударны м механизмом в поверхность исследуемого материала, не обеспечивают определени  прочности движущихс  деталей машин, испытывающих в процессе работы соударени , вызывающие в местах контакт; по вление опасных напр жений и местной деформации .The invention is a method for testing contact contact of samples of materials (in particular metals) ...- Known methods for testing the strength of materials based on the use of tips of indenters) with a hemispherical end surface embedded by a percussion mechanism into the surface of the material being studied, not provide the determination of the strength of the moving parts of machines, which in the process of work experience collisions, causing contact at places; the occurrence of dangerous stresses and local deformation.

Этот недостаток устранен в описываемом ниисе способе тем, что два стержневых образца, закрепленные в зажимах испытательной машины ударного действи  и снабженные сферическими наконечниками, подвергают иовтсрным ударам один о друго с заданной энергией удара и по площади иробрщии .или .диаглетра получаемого на наконечниках отпечатка , затрачиваемой энергии и числу ударов, вызывающих по вление трещин на образцах, определ ют ис1:омую величину контактного см ти .This disadvantage is eliminated in the method described by Nis by the fact that two core specimens, fixed in the clips of a percussion testing machine and equipped with spherical tips, are subjected to various blows one to the other with a given impact energy and area of the impactor on the imprint of the imprint, which is spent The energy and the number of blows causing the appearance of cracks on the specimens are determined by the amount of contact sm.

На чГртои;е изображена cxeivia испытани  образцов на контактное см тие.Figure 2 shows an example of contact specimen testing.

Техника осуществлени  способа испытани  состоит в том, что испытуемые стержневые образцы 1, закрепленные в занчиме 2 ударной испытательной машины (например, копра) и снаб сенные полусферическими наконечнигшми , подвергают повторным ударам один р- другой с определенной задагиюй.. энергией и определенное число раз до по влени  трещин на испытуемых образцах.The test procedure technique consists in that the test core samples 1, fixed in test 2 of the impact test machine (for example, copra) and equipped with hemispherical tips, are subjected to repeated blows one p - the other with a certain task. Energy and a certain number of times before the appearance of cracks on the test specimens.

Основным показателем стойкости испьгтуемого материала против контактного см ти  принимаетс  площадь проекции отпечатка или его диаметра , полученного на испытуемых образцах после определенного числа ударов при заданной энергии удара. Дл  получени  исчерпывающей характеристики поведени  материала при тгонтактном см тии строитс  график зависимости площади от диамет-ра отпечатка, получаемого от числа ударов при заданной энергии удара. Измен   величину энергии удара, можно получить семейство кривых, которые наиболее полно отражают стойкость испытуемого материалаThe main indicator of the durability of the material used against the contact cm is the area of the projection of the imprint or its diameter obtained on the test specimens after a certain number of shocks for a given impact energy. To obtain an exhaustive characteristic of the behavior of the material during tactical contact, a plot is plotted against the diameter of the imprint obtained from the number of impacts with a given impact energy. By changing the magnitude of the impact energy, you can get a family of curves that most fully reflect the durability of the test material.
