随着新材料、航空、航天和高端制造业等产业对材料服役性能测试与保障能力的要求不断提高,吉林大学等单位联合开展了跨尺度原位力学测试新技术与仪器装备的研制工作,掌握了具有自主知识产权的材料微观力学性能测试仪器及其批量制造的核心关键技术,提升了我国自主研制仪器的技术水平。研究人员攻克了原位力学测试仪器装备的设计、制造与标定等关键技术难题,突破了原位测试仪器装备精度校准的技术瓶颈,使加载力分辨率达到10mN、加载位移分
As new materials, aerospace, high-end manufacturing and other industries on the service performance testing and assurance capabilities continue to improve, Jilin University and other units jointly launched a cross-scale in situ mechanical testing of new technologies and equipment research and development work to master With the independent intellectual property rights of materials, mechanical properties of micro-testing equipment and its core batch manufacturing core technology to enhance our own independent research and development equipment, technical level. Researchers have overcome the key technical problems of design, manufacture and calibration of in-situ mechanical testing instruments and equipment, broke through the technical bottleneck of precision calibration of in-situ testing equipment, and made the resolution of loading force reach 10mN.
