Mechanical test device for rubber and plastic material in high-temperature environment

The invention provides a mechanical test device for a rubber and plastic material in a high-temperature environment, which is based on an optical extensometer which is positioned inside a shell and is provided with a plurality of image acquisition components and a control host positioned outside the shell, under the condition that non-contact measurement is achieved and the safety of testers is guaranteed, high-precision measurement of the scale distance in a sample thermal extension test within a large view field can be achieved, meanwhile, the defect that a traditional measuring instrument cannot measure a sample for a long time is overcome, full-time measurement in the test process can be achieved, a scale distance time-displacement curve is obtained, and the measurement accuracy is improved. An accurate and favorable basis is provided for scientifically evaluating the high-temperature performance of the sample. 本发明提供了一种高温环境橡塑体材料的力学试验装置，基于位于壳体内部的具有多个图像采集组件的光学引伸计和位于壳体外部的控制主机，在实现非接触测量保证试验人员安全的情况下还可实现大视野范围内样品
