Application of polymer composite materials in the manufacture of the frame of the cab of a road roller weighing 17 tons

The presented article presents the results of the analysis of the possibility of using polymer composite materials to replace the metal part of the power structure of the cabin and subframe of a 17-ton road roller. Currently, polymer composite materials are widely used both in mechanical engineering and in the production of road construction machines, these materials are mainly used to manufacture parts of the plumage and lining of cabins, both internal and external, the proposed work considers the possibility of replacing the metal structure completely with a cabin structure made of polymer composite material using certain fillers that provide the required physical and mechanical properties under the established loads. When using polymer composite materials, certain advantages are provided, both technological and operational. Polymer materials will ensure a longer service life of such structures due to their high strength characteristics and chemical properties. For example, polymer composite materials are much less susceptible to corrosion wear and have a wider operating temperature range. To ensure these properties, a binder and filler were selected, their optimal proportions were calculated to obtain the required properties, and a 3D model of the cabin frame load structure was created. At the second stage, computer simulations of loads on “fops” and “rops” were carried out in a 3D design environment using the load values ​​provided in the technical regulations of the customs union. The results obtained confirm the rationality of using polymer composite materials in such load structures, which reliably ensure the preservation of the driver’s area without critical damage when the loads in question occur.
