Fitting In

Cable design and routing is a time-consuming and costly process for industrial complex products, traditionally it is finished by experienced engineers through soft lead or aluminum wire fitting in physical models, or by automatic or semi-automatic computing method in CAD system, but both with little success. In this paper, a new haptic-based interactive method is proposed. After rigid product models are loaded from CAD system, a geometry modeling method is used to represent cable shape, a physics modeling method for calculating cable deformation, and a haptic modeling method for interaction and force feedback. In this prototyping system, the user can define cable position and path, change its shape and size, and then simulate the design and routing process with haptic to feel the touch, collision and force feedback.

Force Characteristics

The design of safety relief valves depends on knowledge of the expected force-lift and flow-lift characteristics at the desired operating conditions of the valve. During valve opening the flow conditions change from seal-leakage type flows to combinations of sub-sonic and supersonic flows It is these highly compressible flow conditions that control the force and flow lift characteristics. This paper reports the use of computational fluid dynamics techniques to investigate the valve characteristics for a conventional spring operated 1/4” safety relief valve designed for gases operating between 10 and 30 bar. The force and flow magnitudes are highly dependent on the lift and geometry of the valve and these characteristics are explained with the aid of the detailed information available from the CFD analysis. Experimental determination of the force and flow lift conditions has also been carried out and a comparison indicates good correspondence between the predictions and the experiment. However, attention requires to be paid to specific aspects of the geometry modeling including corner radii and edge chamfers to ensure satisfactory prediction.
