Testing machineSelection is a very important thing. It directly affects the accuracy of later use and test results. Resolution is an important parameter of the test machine. Appropriate resolution will be conducive to the measured resolution and measure smaller indexing. Effective resolution and dynamic performance are a contradiction. Blindly improving the effective resolution is at the expense of dynamic performance (bandwidth). The reduction in bandwidth directly leads to the phenomenon that material yield fluctuations are not obvious and even yielding is a platform. Therefore, when selecting, these parameters must also be considered effectively.

The data collected in the material test are loads and deformations of the material at the same time. If the two are not synchronized, the load will deform forward or deformation will deform forward forward. For the problem that the same load corresponds to two deformations when measuring elastic material in the back-to-back process, the back-to-back process curve does not overlap. Select the required test machine load (i.e. range) according to the load of the test material. It is best to select the test load of the recommended material at about 70%-90% of the test machine range. This not only ensures the resolution of the test but also extends the service life of the test machine.
