The calculation of the normal pressure on the supporting surface of the transport of a caterpillar given the overloading of individual rinks
The method to calculate the normal pressure on the bearing surface of the propeller transport tracked vehicles. The research object is the chassis of the tracked vehicle and technology platforms based on them. Purpose - to propose a methodology of calculation of the normal pressure considering the focal nature of the interaction of the bearing surface of the propeller with the ground and the impact of the scheme applied to the chassis of the external forces. A brief review of the relevant literature. When calculations take into account the geometric, kinematic and power features specific suspension systems. The features that distinguish the mover transport the car from the engine of a crawler tractor. The necessary design scheme and explanatory illustrations. Mapped traditional approaches to the problem of determining the normal pressure on the supporting surface of the track Assembly and current views on this issue. Applied author mathematical model that allows to estimate the distribution of normal pressures on the bearing surface in the case of extreme overload rollers. The necessary calculation based and presents the results of the calculation of the values of the normal pressure and maximum depth gauge for cohesive soils and non-cohesive types. As an example, the selected chassis layout tracked vehicles BTR-D, in possession of authors. Summarizes the main results of the calculations. The analysis of the calculation results and the proposed explanations for the observed effects; the conclusions about the feasibility of the proposed technique. The proposed scope developed computational methods. In the bibliography the basic scientific work on the subject matter of this article. Presents information about the authors.
