摘要
The legitimacy of the assumptions made in work (Wolny & Matachowski, 2010), which led to the decoupling system of four dynamic equations describing the motion of the mining vessel, forming two independent systems of two equations - which can be now solved analytically - was decided to verify by seeking the numerical solution to that system of equations.
Detailed analysis were engaged for the following parameters in the conveyance shaft steelwork system:
- spectral density of displacement of the point x(A) (skip head),
- spectral density of displacement of the point x(B) (lower frame),
- spectral density of acceleration of the point x(A),
- spectral density of acceleration of the point x(B).
The results of these parameters are presented in the paper in graphical form, in a confrontation with the results of the same parameters obtained from the analytical solution enabled them to establish their high compliance. There is a noticeable tendency to increase the maximum density values of the spectral parameters obtained from the analytical solution, as well as a slight displacement towards lower frequency values relative to the value of the spectral density of the same parameters derived from the numerical solution of dynamic equations of motion
The results obtained confirm the validity of the study made (Wolny & Matachowski, 2010) simplifying assumptions that led to the decoupling the system of dynamic equations, consequently, the recognition of the head and the lower frame as independent.
