“…To control the pair of muscles, a part of the pressure characteristics of the valve, shown in Figure 5, was used. Accurate author's research presented in the works [14,15] showed asymmetry in the valve operation, leakage and non-linearity.…”

This article presents a test stand used to determine the angle control of a pair of pneumatic artificial muscles PAM, which work antagonistically like natural muscles, e.g. in the human arm. The muscles were designed and produced at the Kielce University of Technology. The technical and functional parameters of the muscles were determined on the basis of experimental research. The Ziegler-Nichols method of tuning a PID controller on the basis of the step response measurement of the open system is also presented for the analysed problem. Experimental research was performed on angle control of a pair of pneumatic muscles with a PID controller.

“…Pneumatic systems are currently the most ecological and economical media for industry, but they are used in less demanding processes. The complexity of designs and multiplicity of applications of pneumatic systems results mainly from the advantages of compressed air, which enables the generation of significant forces, and from a large assortment of valves [ 19 , 20 , 21 ] and pneumatic components. In industry, pneumatic installations for the distribution of compressed air are commonly made of PP-R polypropylene or PP-R polypropylene with an external aluminum layer and on fasteners, connected by welding with a temperature resistance up to 60 °C and a maximum pressure of 20 bar.…”

Prompt Determination of the Mechanical Properties of Industrial Polypropylene Sandwich Pipes

et al. 2021

A simple and prompt method to determine the mechanical properties of industrial multilayer extrusion polypropylene pipes for a gravity sewer network is suggested. The engineering formulas included for calculating the permissible thickness and relative position of a foam core in the pipes are based on a linear-elastic approximation and the rule of mixtures. The applicability of the approximation was justified experimentally during investigation of the effective tensile characteristics of single- and multilayer pipes and each layer specimen by using traditional tests and finite-element calculations. The results obtained were used to formulate engineering recommendations for calculations of this type.

“…Luo et al [17] contributed to cavitation theory by studying the collapse of two cavitation bubbles with a high‐speed camera. Experiments by Takosoglu et al [18] on a servo valve provided a good experimental reference. Yan et al [19] provided good theoretical guidance for designing a servo valve by studying its nozzle jet mechanism.…”
