Abstract

The invention discloses a magnetically controlled shape memory alloy material drive characteristic test platform and a test method, and belongs to the technical field of measurement devices. The testplatform comprises a C-shaped base and an electromagnet system for providing a magnetic field and a horizontal guide rail which are fixed on the C-shaped base, wherein a sliding block, a force sensor,a displacement sensor, a proportion electromagnet, a spring, a pulley block gravity unit, a fine tuning hand wheel and other components are arranged on the horizontal guide rail; through combinationof different components, a module with different test functions is formed, and the test of the drive characteristics of the material under a constant-force load, an elastic load or a load with specific change rule is realized on the same test platform. With modular design, the test platform disclosed by the invention has the advantages of simple structure and high universality. When the test platform is used for testing, the operation is simple, and the test needs for different functions can be met.

Description

technical field [0001] The invention belongs to the technical field of measuring devices, and in particular relates to a test platform and a test method for the driving characteristics of a magnetically controlled shape memory alloy material. Background technique [0002] Smart material refers to a new type of functional material that can sense environmental stimuli and respond appropriately. It is one of the important directions for the development of modern high-tech new materials. Magnetostrictive smart materials can deform under the control of an external magnetic field. It is the current smart material. Important members of the family, such as (super) magnetostrictive materials, and magnetic control shape memory alloy materials. Among them, magnetically controlled shape memory alloys can be used to make valve drivers, energy recovery devices, sensors, etc. because they have the characteristics of fast response speed of piezoelectric materials and magnetostrictive materi...
