Investigating Strength Of Materials By Application Of Mechanical Stress
(AREA)
Abstract
FIELD: high-precision elements and constructions; can be used in precise mechanical engineering. SUBSTANCE: material or element are subjected to impact effect in the direction of action of residual stress with a period of impact effect of at least twice lower than the fall time of shock waves in element material; the minimum impact force and duration of impact working are preliminarily determined according to the intensity of variation of one of the material physico-mechanical characteristics, for example, according to the temperature coefficient of linear expansion or modulus of material elasticity. EFFECT: enhanced capacity and reduced power consumption.

Изобретение относится к высокоточным деталям и конструкциям и может быть использовано в точном машиностроении. Способ заключается в том, что материал или деталь подвергают ударному воздействию в направлении действия остаточного напряжения с периодом ударного воздействия не менее чем в 2 раза меньшим, чем время затухания ударных волн в материале детали, причем минимальные силу удара и длительность ударной обработки предварительно определяют по интенсивности изменения одной из физико-механических характеристик материала, например по температурному коэффициенту линейного расширения или модулю упругости материала. В результате повышается производительность и снижаются энергозатраты.The invention relates to high-precision parts and structures and can be used in precision engineering. The method consists in the fact that the material or part is subjected to impact in the direction of the residual stress with a period of impact not less than 2 times shorter than the decay time of the shock waves in the material of the part, and the minimum impact force and duration of impact processing are preliminarily determined by the intensity changes in one of the physical and mechanical characteristics of the material, for example, by the temperature coefficient of linear expansion or the elastic modulus of the material. The result is increased productivity and reduced energy consumption.
