Optimum assembly design utilizing a behavioral modeling concept

Abstract

This paper presents a versatile and economical knowledge‐based assembly design of blade and shell assemblies by employing behavioral modeling concepts. Behavioral modeling is a new generation CAD concept aimed at achieving ultimately optimum results with the efforts made in the early stage of the product development cycle. As a result, the assembly process of any odd‐configured parts such as torque converter blades, can be accurately planned, and made adaptable to all potential in‐process alterations due to either changes of components design or that of the assembly kinematics. Optimum assembly design is achieved when the volumetric interference meets a desired value based on an expert's determination. Experimental verification of the proposed optimum assembly design conducted in Luk, Inc. with two different blades' assemblies demonstrates satisfactory results.

Analysis and evaluation for assembly behaviour of reheat stop valve based on virtual prototyping

“…A computer prototype modelling system for three‐dimensional (3D) mechanical assemblies with deformable components was implemented (Fang and Liou, 1997), which modelled the elastic behaviour using the finite element method. Research has also been carried out in optimum assembly design (Farahati, 2001; Lin and Farahati, 2003a,b), inserting and mating analysis, rigid part assemblies using compliant devices aided by a robot (Whitney, 1982), and feed ability of parts in the assembly process (Kim et al , 1992). Topics that have contributed significantly to the field of virtual prototyping application also include: VR‐based sensitivity analysis and shape design of assembled components (Yeh and Vance, 1997) and the use of multi‐modal virtual environments for design for assembly (Gupta and Zelter, 1995).…”
