Anotācija The paper describes the dynamics of the vibration under pressure. The testing machines Instron and Zwick were realising vibropressing regime. The ma- terial testing machines were used for experiments with raw concrete. The form of samples was cylindrical with diameter 84.5 mm. The series of experiments were conducted according to the Mean Square Error Latin hypercube design [1]. All experiments with a raw concrete were the examination of the influence of vibro- pressing characteristic parameters (pressing load, vibration force amplitude and frequency) on the quality of concrete samples. The vibropressing regime is de- scribed by formula f=f0+fAsin(ωt) was realizing changing three parameters - f0 pressing force (10-50kN), fA force amplitude (1-11kN) and frequency(10-50 Hz). Fourier analysis was used for the analysis of realized parameters. The testing ma- chines implement some input parameters very accurately, therefore a locally weighted sinusoidal approximation with Gaussian weighting function was [2,3] used for smoothing and numerical differentiation of the registered functions. The correlation between input parameters investigated.
