Abstract In the present paper results of definition of natural frequencies of simply supported-clamped thin cylindrical shells from the focused fiberglass considered as homogeneous monolithic anisotropic material are presented. Constants of elasticity of a material of a shell depend on an angle of winding of fiber glass. Natural frequencies of a shell are found in the assumption, that central lines have the spiral form. Constructions of dependences of frequencies from an angle of winding of fiber glass for various parameters of wave formation and the geometrical sizes of a shell are executed.
Keywords

cylindrical shell, fiberglass, natural frequency, angle of winding fiberglass

Abstract Results of is final-element modelling of the basic details of a reducer of the motor-wheel used in career dump-body trucks are resulted. The main pressure, equivalent pressure, deformations and movings are defined. The most pliable places in a design of a reducer of a motor-wheel are revealed, expected concentrators of pressure are specified. Recommendations about increase in rigidity of a design of a reducer of a motor-wheel and to reduction in it are given concentration of pressure.

Abstract When testing by sweep method the items are operated by the vibrations at all the frequencies within the range. Choosing the conditions of the accelerated tests on the action of sinusoidal vibrations with variable exciting frequency requires determining of dynamic amplitude-frequency characteristics (AFC) of items. The solution of differential equation of the load kinematic excited motion and the results of theoretical and experimental study of AFC of mechanical systems under transient vibrations are given. The parameters of the dynamic AFC depending on the speed of frequency scanning are worked out. Data processing are resulted in receiving empirical dependences for evaluating the maximum value of acceleration-relative transfer ratio, the ratio of the maximum of dynamic AFC frequency shift relative to the frequency of natural oscillations, coefficient of expansion of the dynamic resonance frequency band, the ratio of average AFC frequency shift relative to the frequency of natural oscillations for the exponential and linear laws of frequency scanning. The experimental data correlated with a high degree of compliance with theoretical results.
