Effect of Particle Damping Absorber on the Vibration Transmission of Roll and Its Energy Consumption Characteristics

【Purposes】 In order to suppress the vertical vibration of the mill during rolling process, a multi-degree-of-freedom particle damping absorber (PDA) combined with dynamic vibration absorber and particle damping technology for vertical vibration control of the roll is propsed. Besides, the vibration transfer and energy dissipation behavior of the coupled Roll-PDA system is in vestigated. 【Methods】 A four-degree-of-freedom vertical vibration model of the coupled system is established, and the s...

Finite Element Analysis on the Fixation Effect of Thermoplastic Film Opening

【Purposes】 Radiation therapy is an important method of personalized tumor treatment. Thermoplastic film is often used to fix the patients position in clinical practice to ensure the repeatability and accuracy of treatment. 【Methods】 On the basis of CT images of a patient with head tumor, two different kinds of thermoplastic membrane finite element models were established. The material properties of thermoplastic film were measured by tensile experiments, and the displacement and stress respon...

Study on the Performance of New High Temperature Heat Pump Mixtures as Alternatives to R245fa

【Purposes】 At present, the contradiction between energy supply and demand is increasingly intensifying, and high-temperature heat pumps, as an energy-saving and emission-reduction technology, can upgrade a large amount of low-grade waste heat to high-grade energy for utilization. 【Methods】 Five environmentally friendly heat pump working fluids are proposed, R1233zd(E)/R1234ze(Z)(0.15:0.85), R600a/R1233zd(E)(0.70:0.30), R600a/R1233zd(E)/R600(0.01:0.15:0.84), R600a/R1233zd(E)/ethylene oxide ( 0...

ALOS DEM-Based Extraction of Geomorphological Feature in Xishan Mining Area of Shanxi Province

【Purposes】 Geomorphology is the most important physical geographical element of the Earths surface system, and its morphological division is of great significance to the study of geospatial differentiation. 【Methods】 Xishan mining area in Shanxi Province was taken as the research area, on the basis of the ALOS 12.5 m DEM data of the area, the optimum analysis window of the relief amplitude was determined to be 1313 (0.026 4 km2) according to the window increment analysis and mean-variation an...
