Some aspects of the experimental assessment of dynamic behavior of the railway track

Solonenko V., Mahmetova N., Musayev J., Kvashnin M., Alpeisov A., Zhauyt A.

Journal of Theoretical and Applied Mechanics

2017

Vol. 55 nr 2

421--432

The paper suggests application of an experimental method for the assessment of the dynamic effect of a locomotive underframe on the railway track. The assessment is to be based on spectral analysis of the response of structural elements of the railway track undergoing a shock pulse. Application of digital measuring systems for monitoring of motion of the train is also proposed.

Kinematic synthesis of spatial linkages with spherical pairs

Kosbolov S., Zhauyt A., Kosbolov S.

Journal of Theoretical and Applied Mechanics

2016

Vol. 54 nr 1

75--85

A solution to the problem of synthesizing an initial three-dimensional kinematic chain with spherical and rotary kinematic pairs is presented. It is shown that this chain can be used as a structural module for structural-kinematic synthesis of motion of a three-dimensional four-link generating lever mechanisms by preset positions of the input and output links.
