Analytical method for calculating stress-strain state of rubber cord pipes with axial displacement of flanges
To determine the performance characteristics of rubber-cord pipes under the influence of internal overpressure taking into account the relative displacement of the ends (flanges), an unconventional method of approximate analytical solution and the subsequent increase in the accuracy of calculating...

| description | To determine the performance characteristics of rubber-cord pipes under the influence of internal
overpressure taking into account the relative displacement of the ends (flanges), an unconventional
method of approximate analytical solution and the subsequent increase in the accuracy of calculating
the stress-strain state of rubber-cord shells with tensile cord casing is used. The fundamental difference
between the force created by the rubber cord pipe and the spacer force is taken into consideration.
The calculation is compared with the results of experiments on fracture, the calculated value of the
excess fracture pressure fits into the confidence interval of the spread of experimental data. Examples
of constructing isobar power characteristics of sleeve-type pneumatic shock absorbers (sleeve tensilecompression shock absorbers) are shown and the features of their behavior are analyzed at different
values of the operating and design parameters of the rubber cord pipe.
The results are intended for engineering calculations and the optimal design of rubber cord pipes used
to connect pipelines, or as air shock absorbers to protect technical objects from vibration and shock |
