特征 Features
本設(shè)備可以實(shí)現(xiàn)靜態(tài)特性、動(dòng)態(tài)物性兩方面的檢查,也能實(shí)現(xiàn)壓縮、拉伸兩方面的檢查。
The tester can test both static and dynamic characteristics.
In addition, it can perform both compression and tensile tests.
動(dòng)態(tài)特性的檢查范圍,根據(jù)主體結(jié)構(gòu)的不同分為5--30Hz(類型A)和5---100Hz(類型B)2種類型。
Depending on the main frame structure, either 5-30Hz(Type A)or 5-100Hz(Type B)dynamic
characteristic testing is possible.
