The paper analyzes complex engineering systemliquid-gas shock-absorption system of landing gear. The system has a combined discrete-continuous behavior. Such systems are called hybrid systems. Simulation is performed in order to improve the control law and minimize the overload effect when landing on the airframe. The analysis is carried out by computer simulation with the use of specialized tools.

The battery vehicles are widely used in industry and transport therefore the problem of energy saving is actual. There are different ways of solving this problem and one of them is the usage of power filters for stabilization of accumulator battery cur. The method improves the battery operation conditions thereby. increas€s the time of race between charges of autonomous mean of transportation.The calculation and the choice of the power filter are detennined by the minimum of a rootmean-square error because the load of drag-out electric drive is random. The main goal is to find the kind of transfer function WOTIT(P) when statistical characteristics of guided and dithering impacts are known and the value of summary error would be minimal [2] (figure 1).

Abstract. The paper deals with the parametric modeling method of virtual mannequins for the purposes of design automation in clothing industry. The described approach includes the steps of generation of the basic model on the ground of the initial one (obtained in 3D-scanning process), its parameterization and deformation. The complex surfaces are presented by the wireframe model. The modeling results are evaluated with the set of similarity factors. Deformed models are compared with their virtual prototypes. The results of modeling are estimated by the standard deviation factor.
