КОНСТРУКТИВНЫЕ ОСОБЕННОСТИ КАНАТНЫХ ЛЕСОТРАНСПОРТНЫХ СИСТЕМ НА МЯГКИХ ПНЕВМАТИЧЕСКИХ ОПОРАХ

Abstract

The article presents the results of studies on an alternative type of forest transport based on cable systems equipped with soft pneumatic supports. The relevance of the research is dictated by the fact that currently logging processes are shifting from the most accessible forest areas to hard-to-reach mountain areas with characteristic signs of environmental dependence with the dense presence of water bodies such as rivers, lakes, swamps, which in its turn can also serve as transport corridors to move harvested wood. Based on theoretical and experimental studies, the authors have proposed a technology that allows efficiently and environmentally safe logging in the presence of various hydrological barriers, including swamps. The technological scheme of the use of rope complexes, the construction of a soft pneumatic support of an arch type, as well as a working experimental prototype of this timber transport system are presented. The results of calculations and examples of deformation isopoles are given, which make it possible to evaluate the loads arising in the design of an arch pneumatic support depending on the mass of the cargo held and the air pressure inside the support. LIRA software package was used to simulate the load process. The research results confirmed the possibility of using cable forest transport systems on soft pneumatic supports in the logging process
