Solution of some problems on optimization of one-dimensional models of instruments elastic elements

Based on the one-dimensional models constructed, we consider the use of num erical optimization when calculating the elastic deformation of instrument' s design elements. We present the calculations of deformations for rod-like elements with complex-shaped cross section, round plates, and a conical sh ell under angular harmonic loading. Using the criteria of frequency as the base, we optimized the design parameters of the ribbed cantilever beam of c omplex-shaped cross section.
