Background
Stiffness refers to the ability of a material or structure to resist elastic deformation when subjected to a force. Is an indication of the ease with which a material or structure can be elastically deformed. The stiffness of a material is usually measured by the modulus of elasticity E. In the macroscopic elastic range, stiffness is the proportionality coefficient of part load proportional to displacement, i.e. the force required to cause a unit displacement. In the prior art, the deformation of measuring components such as a guide rail and a rotary table is mainly changed by adding weights and other non-automatic modes, and although the modes can measure the rigidity and the bearing capacity of the measuring components, the measuring effect of the core components of the high-precision machine tool researched at present is not good. The traditional modes of adding weights and the like can be used for simple measurement of non-precise equipment, and the ultra-precise equipment is greatly influenced by factors such as environment, noise and the like, so that the measured data is seriously distorted.
