| Popis: | New generation of transport and technological vehicles and agricultural transport means has been developed, based on the principle of design modularity with application of three-dimensional supporting systems of frame construction. Design decisions were implemented and introduced as the Ural-432065 all-wheel vehicle chassis with replaceable technological superstructures. A device for removing of replaceable technological superstructures from vehicle chassis and for their installing on support for storage was also developed. Three-dimensional supporting construction in the form of weld-fabricated steel pipe frame was selected. It was adapted for installation on technological superstructures and unified for bracketry on vehicle frame. Strength calculations were carried out. Sections of structural elements and method of their manufacturing were selected. Prototypes of devices were made on the basis of developed design documentation and installed on the superstructures: on the distributor of solid mineral fertilizers by means of threaded assembly; on the superstructure for hauling and subsoil fertilizing of liquid fertilizer organics by welding to load-carrying parts of the tanker. Computer simulation of the functional of replaceable technological superstructures allowed to estimate the efficiency of design decisions. Test results confirmed the data of analytical studies. Consequently, transport and process operations are implemented, both on open roads and in the field with satisfying of environmental and agrotechnical requirements. If there are several technological superstructures in the farm, it is possible to use only one vehicle chassis, which reduces the dead time and the impact of seasonality works factor. |
