Although pressure compensating emitters (PCE) have many advantages, they are difficult to develop and very costly. Traditional PCE are composed of emitter structures and compensating diaphragms. Their manufacture is very difficult and time-consuming. In this paper, we invented novel PCE with variable flow channels, which are designed as integrated structures with pressure compensating barriers, and manufactured three of them with different structures based on the rapid prototyping/rapid tooling technology. The pressure-flow test showed their behavior indexes were 0.009, 0.008 and 0.011, respectively, indicating this type of novel PCE have remarkable compensating effect.

Diffractive optical element (DOE) is widely employed to convert light wave fronts in many different applications. This study demonstrated a precision hybrid rapid tooling for manufacturing the DOE. The transcription rate in the rapid tooling manufacturing process is about 92.5%. The transcription rate in the molded part is about 95.1%. Hybrid rapid tooling technology not only reduces the fabrication cost of rapid tooling but also has higher form accuracy and higher thermal conductivity. In comparison with conventional method for fabricating a pair of rapid tooling of a new DOE, a cost reduction of 60.4% can be achieved using a hybrid rapid tooling technology.

Abstract To strengthen operational process analysis and normalize information requirements description in systemic operations based on information systems, a new operational architecture modeling method is proposed from the perspective of information flow analysis. An operational architecture modeling framework based on information flow analysis is established by referring to American department of defense architecture framework (DoDAF V2.0). Concepts of entities, relationships, attributes and mapping rules are defined. Operational activity model, operational nod model and information alternation model are constructed. Finally, aerial assault operation is taken as an example to demonstrate the modeling process. Simulation results show that operational process analysis is more refined and information requirement descriptions are more visible, normal and clear, which validate the feasibility and validity of the method and models.

Major Shift

<p>To solve the tool-making bottleneck, it is fundamental to integrate rapid manufacturing methodologies for rapid tooling, which reduces the lead-time to manufacture the tools while improving their quality. Rapid tooling (RT) is a progression of rapid prototyping (RP). RT is the art of producing tooling directly from CAD models of the part. RT technology plays a major role in increasing the pace of tooling development. This paper describes the role of RT according to the current market situation. An ample review of examples of rapid tooling indicates a new trend of tooling practice. This trend in manufacturing based on rapid prototyping and rapid tooling has already had a dynamic impact on the engineering environment.</p>

As soft elements for force transmission, braided fiber ropes play important roles in many fields where the fiber ropes are used bent over sheaves, while the relevant experiments are time-consuming and expensive. Computational simulation is a promising choice for evaluating the performance of fiber ropes when bent over a sheave. This article presents two methods that could be employed to build a model of braided rope bent over a sheave. One is the mathematical method which deduces the exact mathematical equations of braiding curves based on the Frenet–Serret frame. The spatial equations, considering the phase difference of strands in the same direction and the difference of strands’ projection in different directions, are discussed carefully. The final equation of braided strands is confirmed by modeling the braided rope in Maple® 17. The other method, which is inspired by the analysis of braiding movements, is based on the intersection of surfaces of braiding surface and helical surface which are introduced and defined based on the motion analysis of bobbins and take-up roller. The SolidWorks® 2018 is successfully employed to realize the modeling process.
