Summary: The Man/Machine Interaction Dynamics and Performance (MMIDAP) project seeks to create an ability to study the consequences of machine design alternatives relative to the performance of both the machine and its operator. The envisioned MMIDAP capability is to be used for mechanical system design, human performance assessment, extrapolation of man/machine interaction test data, biomedical engineering, and soft prototyping within a concurrent engineering system. This chapter has reviewed the existing methodologies and techniques needed to create such capability. It has attempted to outline ongoing efforts to integrate both human performance and musculoskeletal databases with the host of analysis capabilities necessary for the early design analysis of dynamic actions, reactions, and performance assessment of coupled machine-operator systems.
The multibody system dynamics software program NDISCOS of GSFC and Photon Research Associates can be used for machine and fine grain detail musculoskeletal dynamics modeling; a detailed exposition of its underlying theoretics has been provided herein. The program JACK from The University of Pennsylvania can be used for estimating and animating whole body human response to given loading situations and motion constraints. The basic elements of performance (BEP) task decomposition methodologies associated with The University of Texas at Arlington’s Human Performance Institute’s BEP database can be used for human performance assessment. Techniques for resolving the statically indeterminant muscular load sharing problems can be used for a detailed understanding of potential musculotendon or ligamentous fatigue, pain, discomfort, and trauma problems. The MMIDAP problem as defined herein highlights the conflicting needs and views of groups that focus on machine design and groups that focus on musculoskeletal biodynamics, on human performance and cumulative injury potential.
An attempt has been made to show that there is a critical need to integrate design and simulation tools and to establish multidisciplinary lines of communication. Furthermore an outline is provided of planned integration efforts for human performance analyses, associated databases, and mechanical system design capabilities. This integration effort is expected to provide an ability to perform both stand alone studies and the early system trade studies needed to assess man/machine interaction dynamics and performance.
