Problems solved by technology

The limitation of the existing SMA spring characteristic test is that the continuous relationship between temperature-deformation-elasticity cannot be measured at the same time, and the temperature-controlled driving characteristics of the SMA spring cannot be accurately and intuitively reflected.
Outdated test equipment and cumbersome test methods restrict the development of SMA springs

Abstract

The invention discloses a temperature control driving characteristic testing device for a shape memory alloy spring. The device comprises a mechanical device, electrical equipment and a data acquisition and control system. The testing process is completely controlled by a computer. The temperature and deformation of the shape memory alloy spring are respectively controlled by the working characteristics of a ceramic heating plate and a semiconductor cooling plate and the up-and-down movement of a linear sliding table module. A temperature sensor, a laser displacement sensor and a force sensorare respectively used to collect the temperature, deformation and elasticity data of the shape memory alloy spring. The device has many advantages such as flexible and simple operation, good temperature uniformity, high degree of automation, high measurement accuracy, high efficiency, good general expansibility and the like, and is a machine-electricity-liquid integrated product that integrates many advantages such as intelligent measurement and control, high measurement accuracy, high degree of automation and the like. In addition, the device can further be used for testing the elasticity anddeformation of common springs with high precision.

Description

technical field [0001] The invention relates to the field of shape memory alloy testing devices, in particular to a shape memory alloy spring temperature control driving characteristic testing device. Background technique [0002] Shape memory alloy (Shape Memory Alloy, referred to as SMA) is a new type of smart material with shape memory effect, that is, after the initial shape of SMA is plastically deformed at low temperature, it can still actively return to the original shape when heated to a certain critical temperature. In addition, SMA also has superelasticity, which shows that under the action of external force, its deformation recovery ability is significantly higher than that of ordinary metals, and the strain will recover with the disappearance of external force. With so many excellent properties, SMA is widely used in many fields such as aerospace, mechatronics, biomedicine, bridge construction, automobile industry and daily life. [0003] SMA can be made into tu...
