Abstract

The invention provides an instrument capable of conducting stretching, bending and other types of mechanical loading on a sample under the atmosphere environment, the vacuum environment or various chemical environments. A mechanical loading device comprises an installation platform fixedly installed outside a testing device, a precise electric horizontally-moving unit installed at the end, away from the testing device, on the installation platform, a corrugated pipe installed at the end, close to the testing device, on the installation platform and provided with a rod, and a sample loading unit arranged inside the testing device. Compared with the prior art, the mechanical loading device is simple and compact in structure, low in cost and capable of effectively achieving the aim of conducting mechanical loading in the atmosphere environment, the vacuum environment and various chemical environments such as gas atmospheres of oxygen, nitrogen, argon, even ammonia gas and other corrosive gas.

Description

technical field [0001] The invention relates to the field of electronic technology, and is a mechanical loading device suitable for multi-environment vacuum testing equipment. Background technique [0002] Solid-state gas sensors play an important role in medical diagnosis, environmental monitoring, and personal safety protection. For example, based on SnO 2 The gas sensor prepared by nanowires can effectively detect CO gas, thus, under the monitoring of the sensor, real-time monitoring of the gas can prevent CO poisoning. On the other hand, the properties of many materials will change with the change of the ambient atmosphere. In other words, the properties of materials can be adjusted by changing the chemical environment. [0003] On the other hand, stress and strain in functional materials have a significant impact on their structure and performance. Among them, the stress and strain include the stress and strain in the material under no load and the stress and strain ...
