Abstract

Изобретение относитс  к измерительной технике и может использоватьс  в общей и приборной тензометрии. Цель изобретени  - упрощение и расширение области применени  путем обеспечени  регулировки сопротивлени  тензорезисторов на нехрупких объектах произвольной формы. Дл  этого поверхность объекта 3 тензоизмерений точечно пластически деформируют, с помощью индентора 4 до образовани  лунки 5 вблизи закрепленных тензорезисторов 1 и 2. 3 ил. с SThe invention relates to a measurement technique and can be used in general and instrument strain gauges. The purpose of the invention is to simplify and expand the scope by providing adjustment of the resistance of the strain gauges on non-brittle objects of arbitrary shape. For this, the surface of the object 3 of strain measurements is point-shaped deformed plastically using an indenter 4 before the formation of a hole 5 near the fixed resistance strain gages 1 and 2. 3 Il. with s
