In the process of agricultural production, a large percentage is represented by transport works. The transport of agricultural products and materials is carried out in a proportion of 70…80% on public roads, which means that all means of transport that travel on these roads must be designed and equipped in strict accordance with the regulations in force on road safety. This article presents the results of the research conducted for the construction of a two-part tipper trailer, equipped with two axles, designed in cooperation with a Romanian company. The activities carried out fell into the category of applied research. Three-dimensional design can ensure precision in execution, shortening the time to supply a product on the market, reducing the time required for the entire flow, from design to manufacturing, testing and mass production. In order to accelerate the research and shorten the period until the realization of the experimental model, in the design phase simulated research was performed, using the SolidWorks Simulation module. These researches contributed to the correct choice of materials, as well as to the precise determination of the dimensional characteristics of the various subassemblies. The main subassembly studied by virtual testing was the axle of the trailer. A good dimensioning of the trailer components ensures the safety in operation and contributes to the optimization of the trailer production process, eliminating the irrational consumption of raw materials. The integration of the subassemblies tested by simulation, and later by experimental research in real working conditions, led to the performing of an agricultural trailer with a payload of 7 tons, contributing to the development of the agricultural machinery construction in Romania. The article presents the results of the static analysis of the trailer axle of the rolling system, using virtual testing to look for vulnerabilities, as a necessary stage of the development process.
