Abstract

The invention discloses a flexible hinge micro-component tensile testing device with clamping centering guide functions. The flexible hinge micro-component tensile testing device is characterized by comprising clamping mechanisms, a loading mechanism, a centering mechanism, a tension sensor, a grating sensor, a movable-end supporting mechanism and a fixed-end supporting mechanism. The flexible hinge micro-component tensile testing device has the advantages that clamping required by micro-component tensile tests and micro-nano-scale precision loading can be implemented, the flexible hinge micro-component tensile testing device is excellent in centering in clamping and tensile procedures, and accordingly the shortcoming of measurement errors due to deficiency of clamping centering in existing testing methods can be overcome; the flexible hinge micro-component tensile testing device is convenient to operate and low in cost.

Description

technical field [0001] The invention relates to a mechanical performance testing device for micro-nano materials in the technical field of thin film materials, in particular to a tensile testing device for flexible hinge micro-components with clamping and centering guidance. Background technique [0002] With the rapid development of micro-electromechanical systems (MEMS) technology, micro-components of various materials are widely used in micro-devices. The size of MEMS micro-components generally ranges from millimeters to microns. Due to factors such as processing technology, size effects, and surface defects, the mechanical properties of materials at the micro-scale and those at the macro-scale may vary greatly. Therefore, the mechanical properties of micro-components are an important theoretical basis for the study of MEMS, and are very important for the reliability design of MEMS devices. Uniaxial tensile test is the most direct method to measure parameters such as mat...
