Abstract

The invention discloses a microscale material testing machine with high resolution and variable range, comprising a bracket, a lifting mechanism, a displacement sensor, a gravity block with certain weights and an electronic balance, wherein the lifting mechanism is installed on the bracket; one end of the displacement sensor is arranged on the lifting mechanism; the lifting mechanism is used for lifting the displacement sensor in a height direction; and a first fixture is fixed at the other end of the displacement sensor; the gravity block is placed on the electronic balance; and a second fixture is installed on the gravity block. When a load of 10<-6>N to 1N is measured, a sample is clamped between the first fixture and the second fixture. With the adoption of the microscale material testing machine with high resolution and variable range, microscale measurement can be realized, and the measurement range is 10<-6>N to 101N order.

Description

technical field [0001] The invention relates to an instrument for testing the mechanical properties of micro-scale materials. In particular, it relates to a material testing machine with a variable range, which can be tested in two ways of tension and compression, and can be tested in 10 -6 N~10 1 The micro-scale mechanical property test is carried out in the N range. Background technique [0002] With the development of science and technology, micro-mechanical (MEMS) technology and bio-nano technology are developing faster and faster due to their unique advantages. The mechanical properties of materials used in these technologies are the key to determine whether the technology can be used safely and reliably. These materials belong to micro-scale materials, and the mechanical performance test involves 10 -6 N~10 -1 N range, the traditional material testing machine is limited by the structure and principle, and cannot meet the measurement requirements, so it is urgent to...
