Abstract Modern production of die and mold tools is quite different in comparison with conventional machining. The basic theory of cutting process and cutting geometry is similar, but the techniques and technology is quite different. High-s...
Development survey of roller type breaker,impact type breaker and hammer type breaker The roller type breaker, the impact type breaker and the hammer type breaker application scope is extremely widespread, can to each kind of different degr...
Abstract As automobile body panels are one kind of sheet metal part with groups of free form surfaces, the process planning is more complicated than common sheet metal stamping to implode effectively and practically. Based on KBE, new frame...
The drilling of deep holes with small diameters remains an unsatisfactory technology, since its produc-tivity is rather limited. The main limit to an increase in productivity is directly related to the poor chip evacuation, which induces fr...
热电传感元素热电或热电偶传感元素通常用于测量温度。如果A和B两种不同金属连接在一起,有一个不同的在结合处的电势称为接触电势。这种接触潜在取决于金属A和B和温度TC的结合,并...
This paper investigates the concern that green buildings may promote energy efficiency and other as- pects of sustainability, but not necessarily the health and well-being of occupants through better indoor air quality (IAQ)。 We ask ten...
Abstract The paper presents an idea of an open-loop control of a pneumatic positioning system consisting of a pneumatic cylinder, inexpensive measurement system and four on-off switching valves. A strategy of four pulses on- off control tra...
Asphalt plug joints (APJs) have been used worldwide because of its low cost, ease of installation and repair, low instance of snowplow damage, low traffic noise and ride comfort。 The service life of APJs is relatively short。 Extending...
ABSTRACT Recent improvements to the capabilities of a hybrid Navier-Stokes potential flow methodology for modeling horizontal axis wind turbine (HAWT) configurations are presented. The study focuses on three issues: the effects of turbulenc...
