Automation- and Simulation-Based Computer Aided Design and Virtual Prototyping of Various Planar and Spatial Parallel Manipulators

Virtual Prototyping of Moog Base

Moog 6 DOF Electric Motion Platform (currently installed in the NYSCEDII) is a (spatial) motion base coupled with an immersive visualization capability, provides an immediate benefit to transportation industries (aircraft, automotive, construction equipment, etc.) involved in product design and training, as well as the location-based entertainment industry.

In this work, we build a virtual prototype of the motion platform in Solid Works, and simulate the kinematics and dynamics in Visual Nastran within MATLAB/Simulink environment. Such framework is beneficial since the designer now has the opportunity to perform forward/inverse kinematics/dynamics in a user-friendly framework before working with the real hardware.

Our proposed study focuses on the development of a low-cost haptically-enabled virtual driving environment and a series of exercises/protocols to serve as an integrated low-cost diagnostic and therapeutic tool for both assessment of UL dysfunction and UL motor rehabilitation. The VE driving paradigm explored over here, offers a promising and cost-effective method for objective/quantitative assessment of UL performance while performing both unilateral and bimanual sensorimotor tasks in the context of one higher activities of daily living (AsDL). Our ultimate goal is to develop a system to permit ease of evaluation of various modalities of driver augmentation and driver assistive technology (visual, auditory and haptic) for various driving condition.

Automated CAD Model Generations

While there is a significant demand for manpower who equipped with Computer Aided Design (CAD) skills, a convenient framework should be streamlined by linking the application program interface (API) capabilities to most CAD software. With this framework, non-engineer may be able to create CAD model by just specifying much fewer parameters with the application software that they are familiar with, yet creating the corresponding CAD model for further engineering analysis by other engineer teams. The aim of this work is to develop an automatic framework allowing users to simply define their design goal so that the automated system can output the design results according to the simulation and optimization. In this work, we developed frameworks for linking SolidWorks-Excel-MATLAB and Solid Edge-Excel using Visual Basic Applications.
