Selection of test machine resolution

The resolution isTesting machineAn important parameter of the problem of suitable resolution will be conducive to the measured resolution and measure the smaller index. The effective resolution and dynamic performance are a contradiction. The blindly improving the effective resolution is at the expense of dynamic performance (bandwidth). The direct result of the reduction of bandwidth is that the material yield fluctuations are not obvious and even yielding is a platform phenomenon, so the selection must also be correct.Testing machineThe parameters of the sequel are effectively considered.

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 choose the test load of the recommended material at about 70%-90% of the test machine range, which not only ensures the test resolution but also extendsTesting machineservice life.
