The universal Arctic rotary-screw rescue vehicle (URV) was chosen as an object of the research. At the moment this rescue vehicle is being developed at the NNSTU named after R.E. Alekseev. A distinctive feature of the URV is the original design of an operated equalizing beam suspension, which has not previously been used for this kind of vehicles. The analysis of equalizer beam various designs is presented in the article. Calculation schemes and simulation models are developed in accordance with the specificity of the rotary-screw vehicle motion. The models and strength calculations have been carried out with standard tools of Autodesk Inventor 2015. The article presents the stress-strain states of different equalizing beam embodiments. The conclusion about reasonability of application of the particular equalizer beam embodiment for developing of a rotor-screw rescue vehicle is based on the performed comparative analysis of researched constructions.
