Abstract

This article studies and compares the efficiency of linear and nonlinear vibration isolation systems. The estimation relies on the value of isolated mass standard deviation due to external oscillation with different spectral densities. The solution of nonlinear differential equation of isolated by nonlinear vibration isolator mass is based on harmonic linearization method. External excitation process is treated as white noise wideband process with different spectral densities. The main interest is attached to the definition of vibration criteria exceedance number for the isolated mass suspended on both types of vibration isolators. The article suggests the application of several practical formulas of exceedance number calculation.
