| Title of the article | Study of the efficiency of spatial mechanisms with a special structure |
| Abstract. | Problem statement. In recent years, construction technologies have begun to use devices whose basic mechanisms are spatial mechanisms with a special structure. To connect the links, they use only rotary joints on rolling or sliding bearings. Since the devices are new and original, protected by patents for inventions, it is necessary to check (study) their effectiveness, the main indicator of which is the efficiency coefficient (efficiency). The purpose of the study is to conduct theoretical and experimental analyses of the efficiency values of such mechanisms on a stand designed for this purpose. Results. As a result of the study of four-, five- and six-dimensional mechanisms on the proposed design of the stand, the values of efficiency from various forces or moments of useful and harmful resistances are determined, recommendations for the use of mechanisms in construction profile devices are given. Conclusions. The significance of the results obtained for the construction industry lies in the creation of new, effective multifunctional devices based on four-link, five-link and six-link spatial mechanisms with a special structure. |
