Abstract
Stress and strain measurements on frames and structures are mainly conducted by the use of strain gauges. A measuring chain applied in such measurements usually consists of strain gauges, amplifiers and data acquisition and logging device. The applicability of such instrumentation mainly depends on its sensitivity measuring repeatability, accuracy and noiseless operation. The key point of this paper is harmonization of measuring properties for the newly invented deformeter with the measuring electronics. Much alike a standard modeling of Mechatronic items, a very specific CLD (Close Loop Deformeter) is optimized throughout coupled modeling, bridging analysis of 3D virtual model and real design of laboratory prototype. Virtual experiment was developed to correspond with actual measurements on the test rig. The idea of rectification factor is introduced into concept of 3D modelling with an innovative CLD research. The focus of the research was kept on the output linearity, measuring range and resolution of the invented deformeter.
