Abstract
Currently, there is a proliferation of vehicles in which the presence of a driver or crew is not provided. They are controlled remotely or are able to move independently. These vehicles belong to the class of unmanned. Analysis of the development stages of the chassis for the traditional crew machine shows that the basic requirements for suspension systems are that the vertical accelerations acting on the driver and crew should not exceed certain values. However, for unmanned vehicles, these requirements are not applicable due to the absence of people in the vehicle body. Considering that unmanned vehicles must move in the same conditions as traditional ones, including cross-country terrain, in some cases along harmonic tracks, there is an urgent task to develop special requirements, which should be taken into account when designing chassis for unmanned vehicles as a separate class of transport equipment. The article proposes to consider some approaches to the definition of such requirements. In particular, when changing the load on the undercarriage elements, it is proposed to proceed from the condition that the vehicle should provide the possibility of transporting the payload, which is usually indicated in the terms of reference. In accordance with this statement, the necessity of studying the most loaded suspension elements is justified, as a result of which it is possible to predict the mass characteristics of the designed chassis. This paper identifies key problems and suggests some ways to solve them. Based on the above material, some conclusions have been made that can be used in further work in solving practical problems in this area.
