Abstract:The objective of this study was to develop a Virtual Reality (VR) design software platform that enables proper three-dimensional visualization of some of the design guidelines for compliant mechanisms, that were challenging to implement load flow visualization method on pen and paper. Some of the challenges include the three-dimensional visualization of the truncated hemispherical band (intersection between the modified input and output hemispherical bands), freedom ray and constraint plane. A three-dimensional VR design platform has been established for designing Spatial Compliant Mechanism (SCM) using load flow visualization method in this thesis research. To achieve this goal, the approach was split into five stages: development of architecture for creating essential features of the design software; development of VR software algorithm through the application of Unity3D assets; testing and validation of the software by checking if the three-dimensional design guidelines, using Load Flow Visualization method, can be implemented for modeling SCM; enabling the user to move around this VR environment and getting an immersive experience of design modelling and analysis; performing trials of simple SCM design modeling on the VR software. The architectural framework necessary for the creation and execution of various key features of the design software was developed and validated. The VR software was finally validated through the application of five single input-single output compliant mechanism designs. All the five designs were found to be compatible with the three-dimensional design guidelines using load flow visualization method. The key inferences of this validation include: a) For the same design problem of a SCM, there can be multiple alternate solutions by changing the number of transmitters and/or intermediate points. b) The deflection direction of intermediate point depends on the orientation of the constraint plane with respect to the point.
