Abstract Positioning systems for machine tools are generally driven by ball screws due to their high stiffness and low sensitivity to external perturbations. However, as modern machine tools increase their velocity and acceleration of positi...
AbstractWith the increasing miniaturization of robotic devices, some actuators are not provided with absolute position sensing, thus making the state of the system unknown at startup. In this paper we present a vision based method for the au...
摘要:在热塑性注塑模设计中,配件的质量和生产周期很大程度上取决于冷却阶段。已经进行了大量的研究,目的是确定能减少像翘曲变形和不均匀性收缩等的不必要影响的冷却条件。...
Abstract This paper presents the development of an Intelligent Cavity Layout Design System (ICLDS) for multiple cavityin jection moulds. The system is intended to assist mould designers in cavity layout design at concept design stage....
Abstract:This work applies modular design concepts to designating beverage-container injection molds. This study aims to develop a method of controlling costs and time in relation to mold development, and also to improve product design. Th...
Abstract Axial compression of aluminium spherical shells of R/t values ranging from 25 to 43 was per-formed under central loading. Quasi-static tests were conducted on an INSTRON machine (model 1197) of 50T capacity. Spherical shells were te...
AbstractThermostatic Radiator Valves (TRV) had proved their significant contribution in energy savings for several years. However, at low heat demands, an unstable oscillatory behavior is usually observed and well known for these devices. Th...
An air conditioner is basically a refrigerator without the insulated box. It uses the evaporation of a refrigerant, like Freon, to provide cooling. The mechanics of the Freon evaporation cycle are the same in a refrigerator as in an air cond...
To produce thin walled products in a precise and stable manner, FANUC have developed electric injection moulding machines driven by a rotary or linear motor to meet the particular features required for moulding products such as wall thicknes...
Abstract: Few studies on the anchorage of reinforcing bars under the compressive conditions have been undertaken. This paper reports the results of 99 pushout tests done to investigate the compressive bond anchorage properties of 500 MPa ste...
