Abstract EN
Many of mechanical energy absorbers utilized in engineering structures are hydraulic dampers, since they are simple and highly efficient and have favourable volume to load capacity ratio.
However, there exist fields of applications where a threat of toxic contamination with the hydraulic fluid contents must be avoided, for example, food or pharmacy industries.
A solution here can be a Pneumatic Adaptive Absorber (PAA), which is characterized by a high dissipation efficiency and an inactive medium.
In order to properly analyse the characteristics of a PAA, an adequate mathematical model is required.
This paper proposes a concept for mathematical modelling of a PAA with experimental verification.
The PAA is considered as a piston-cylinder device with a controllable valve incorporated inside the piston.
The objective of this paper is to describe a thermodynamic model of a double chamber cylinder with gas migration between the inner volumes of the device.
The specific situation considered here is that the process cannot be defined as polytropic, characterized by constant in time thermodynamic coefficients.
Instead, the coefficients of the proposed model are updated during the analysis.
The results of the experimental research reveal that the proposed mathematical model is able to accurately reflect the physical behaviour of the fabricated demonstrator of the shock absorber.
