Polymers in the construction of serviceless sliding bearings
Archives of Civil and Mechanical Engineering - Tập 7 - Trang 139-150 - 2007
Z. Lawrowski
The application range of polymers and their composites in service-less sliding bearings, i.e. bearings that do not require lubrication supervision and maintenance, was defined. A survey of polymers having good sliding properties was done. A general characteristic and classification of polymer composites was presented. The structure and properties of the following composites were discussed: anti-fr...... hiện toàn bộ
Control of a two-degree-of-freedom system with combined excitations
Archives of Civil and Mechanical Engineering - Tập 15 - Trang 492-508 - 2014
H. S. Bauomy, A. T. El-Sayed
In this paper, the chaotic dynamics of parametrically, externally and tuned excited suspended cable is studied with negative cubic velocity feedback. The equations of motion of this system are exhibited by two-degree-of-freedom system including quadratic and cubic nonlinearities. Using the multiple scale perturbation technique, the response of the nonlinear system near the simultaneous primary, su...... hiện toàn bộ

Study of the isothermal bainitic transformation and austenite stability in an advanced Al-rich medium-Mn steel
Archives of Civil and Mechanical Engineering - Tập 22 - Trang 1-14 - 2022
M. Morawiec, V. Ruiz-Jimenez, C. Garcia-Mateo, J. A. Jimenez, A. Grajcar
Isothermal bainitic transformation of a lean medium-Mn steel containing (in mass%) 0.18C–3.6Mn–1.7Al–0.23Si–0.2Mo–0.04–Nb after full austenitization at 1100 ºC was studied by means of high resolution dilatometry. The effects of isothermal holding temperatures ranging from 450 to 350 °C on the bainitic transformation kinetics was studied experimentally characterizing the microstructure present afte...... hiện toàn bộ
The influence of drawing speed on fatigue strength TRIP steel wires
Archives of Civil and Mechanical Engineering - Tập 9 - Trang 97-107 - 2009
M. Suliga, Z. Muskalski, S. Wiewiórowska
The paper assesses the effect of drawing speed on the fatigue strength and roughness of the surface of TRIP steel wires. The drawing process was accomplished on a testing machine and on a block drawing machine, while applying three drawing speeds: 0.02, 0.75 and 1.6 m/s. The performed tests showed a positive effect of drawing speed on the fatigue strength of wires. It was found that the better fat...... hiện toàn bộ

Analysis of the pulsating properties of a high-pressure water jet generated in a self-excited head for erosion processing
Archives of Civil and Mechanical Engineering - Tập 23 - Trang 1-16 - 2023
Monika Szada-Borzyszkowska, Wojciech Kacalak, Kamil Banaszek, Przemysław J. Borkowski, Wiesław Szada-Borzyszkowski
Water jet is an extensively used method for materials processing due to the possibility of operating in different environments (air, water), its safety during working with hazardous materials, and efficiency while cutting hard and brittle rock blocks. In this article, we have presented results of the research on processing aerated concrete by means of pulsating water jest. The discontinuity in wat...... hiện toàn bộ
Advanced high strength steels for automotive industry
Archives of Civil and Mechanical Engineering - Tập 8 - Trang 103-117 - 2008
R. Kuziak, R. Kawalla, S. Waengler
The aim of this paper is to present the basic concepts of advanced high strength steels (AHSS) for use in the automobile industry, including chemical composition design, microstructure and mechanical properties development during thermomechanical processing, production technology characterisation, potential applications and performance in service. AHSS steels are considered to be the major materia...... hiện toàn bộ
