摘要

Procedures of preparation of numerical analysis, consisting in a simulation of cooperation of three different media: steel, liquid and gas undergoes dynamic load were discussed. Modelling of the initial static load of the mechanical system was presented. By using the MSC. Software products the following exemplary computer simulations were made: dynamic load impact on the hydraulic leg as well as effectiveness of the hydraulic leg protection against overload with help of gas accumulator.
