The goal of this study is to develop recommendations for modernization of the construction of load-carrying systems using the STB loom for production of dense fabrics as an example. The analysis of scientific literature on this problem indicates that sufficient attention is not devoted to the effect of load-carrying system elements on the loom feeding system. This study is urgent due to the lack of a general approach making it possible to set the parameters of load-carrying systems with the account of technological requirements and quality of obtained product. To determine deformation energy, a computational model of a loom for production of dense fabrics including a stationary tension bar and a tension tube as a support for warp threads is examined. The deformation energies of the load-carrying and tension systems of STB-180 loom and movements of construction elements depending on the technological force varied in the range of 4000-10000 N is determined using SolidWorks CAD system and finite-element CAE complex ANSYS. The analysis of the calculation results indicates that the deformation energy of the load-carrying system and tension tubes is about 25% of the effective energy used for the fabric production. This fact indicates that it is necessary to improve the rigidity of the load-carrying and tension systems. An improved construction of the loom of production of dense fabrics is suggested based on the results of the studies. This model includes additional supports for the stationary tension bar and tension tube basing on the front tie. The analysis of the calculation results with the account of the suggested improvement of construction elements showed that the deformation energy for the modernized loom has been significantly reduced. The obtained results allowed us to suggest specific recommendations for improvement of the constructions of the load-carrying and tension systems in STB looms for production of dense and technical fabrics.
