OPTIMUM DIMENSIONS OF DWM LOADING FRAME

摘要

In this paper, we are willing to know the influence of the loading frame stiffness through finite element method. FEM modelling has to be run with different force application criteria, and different dimensions of loading frames. In addition, different dimensions of loading frame have been dedicated to run the experiments. The upper plate dimensions showed the superiority over all other loading frame components, and consequently the priority of the rigid loading frame. Hence, supplementary measurements as well as FEM modelling were performed to identify the exact influence and generalize the conclusions through different types of loadcells. An empirical formula (I_X/F) was calculated for comparing different behaviours of loadcells using different models of loading frames. In addition, three types of loadcells were examined for final conclusion.
