ZnS glass is an important infrared optics material,its mechanical properties would be dicey when it worked on high-speed dynamic condition,which cannot be directly calculated and analyzed with normal parameters.In this paper,the mechanical properties of the glass sample were tested through the design test,the test data were analyzed,and the specific material mechanical properties parameters were obtained.The result would help to advance authenticity of the infrared optoelectronic equipment's mechanical simulation analysis,and availably shorten the development periods.
