“…A significant challenge is the need to compute collisions and forces over very short time frames (60-1000 Hz) to support interactive manipulation of complex CAD models. Lin and Gottaschalk [17] and Jimenez et al [18] present a survey of 3D collision detection algorithms and Borro et al [19] organize these algorithms into a taxonomy. Voxel-based methods, such as Voxmap pointshell, have proven especially effective in simulating full 6DOF haptic interactions [20], but the reliance on using approximate geometry for collision detection presents a challenge when faced with assembly of low clearance parts.…”

The scientific and industrial communities have begun investigating the possibility of making product recovery economically viable. Disassembly sequence planning may be used to make end-of-life product take-back processes more cost effective. Much of the research involving disassembly sequence planning relies on mathematical optimization models. These models often require input data that is unavailable or can only be approximated with high uncertainty. In addition, there are few mathematical models that include consideration of the potential of product damage during disassembly operations. The emergence of Immersive Computing Technologies (ICT) enables designers to evaluate products without the need for physical prototypes. Utilizing unique 3D user interfaces, designers can investigate a multitude of potential disassembly operations without resorting to disassembly of actual products. The information obtained through immersive simulation can be used to determine the optimum disassembly sequence. The aim of this work is to apply a decision analytical approach in combination with immersive computing technology to optimize the disassembly sequence while considering trade-offs between two conflicting attributes: disassembly cost and damage estimation during disassembly operations. A wooden Burr puzzle is used as an example product test case. Immersive human computer interaction is used to determine input values for key variables in the mathematical model. The results demonstrate that the use of dynamic programming algorithms coupled with virtual disassembly simulation is an effective method for evaluating multiple attributes in disassembly sequence planning. This paper presents a decision analytical approach, combined with immersive computing techniques, to optimize the disassembly sequence. Future work will concentrate on creating better methods of estimating damage in virtual disassembly environments and using the immersive technology to further explore the feasible design space.

“…Several algorithms that use polygonal data for collision detection were designed by researchers at the University of North Carolina and include I-collide [23], SWIFT [24], RAPID [25], V-collide [26], SWIFT++ [27], and CULLIDE [28].Other methods such as V-Clip [29] and VPS [30] have also been proposed to use in immersive VR applications. A comprehensive review of collision detection algorithms can be found in [31,32] and a taxonomy of collision detection approaches can be found in [33].…”

Virtual reality for assembly methods prototyping: a review

View full text Add to dashboard Cite

Assembly planning and evaluation is an important component of the product design process in which details about how parts of a new product will be put together are formalized. A well designed assembly process should take into account various factors such as optimum assembly time and sequence, tooling and fixture requirements, ergonomics, operator safety, and accessibility, among others. Existing computer-based tools to support virtual assembly either concentrate solely on representation of the geometry of parts and fixtures and evaluation of clearances and tolerances or use simulated human mannequins to approximate human interaction in the assembly process. Virtual reality technology has the potential to support integration of natural human motions into the computer aided assembly planning environment (Ritchie et al. in Proc I MECH E Part B J Eng 213(5): [461][462][463][464][465][466][467][468][469][470][471][472][473][474] 1999). This would allow evaluations of an assembler's ability to manipulate and assemble parts and result in reduced time and cost for product design. This paper provides a review of the research in virtual assembly and categorizes the different approaches. Finally, critical requirements and directions for future research are presented.

Combining physical constraints with geometric constraint-based modeling for virtual assembly

Virtual reality (VR) technology holds promise as a virtual prototyping (VP) tool for mechanical assembly; however, several developmental challenges still need to be addressed before virtual prototyping applications can successfully be integrated into the product realization process. This paper categorizes and elaborates these challenges and then describes how SHARP (System for Haptic Assembly & Realistic Prototyping), addresses them for virtual assembly. SHARP uses physics-based modeling for simulating realistic part-to-part and hand-to-part interactions in virtual environments. A dual handed haptic interface is presented for realistic hand-part interaction. Additional modules are added to utilize the system to provide answers for maintenance issues, virtual training 50 applications and collaborative design. Swept volumes are implemented for addressing maintainability issues and a network module is added for communicating with different VR systems at dispersed geographic locations. Support for various types of VR systems allows an easy integration of SHARP into the product realization process. This has the potential to result in faster product development, faster identification of assembly and design issues and a more efficient and less costly product design process.
