Assessing the validity of kinematically generated reach envelopes for simulations of vehicle operators

Assessments of reach capability using human figure models are commonly performed by exercising each joint of a kinematic chain, terminating in the hand, through the associated ranges of motion. The result is a reach envelope determined entirely by the segment lengths, joint degrees of freedom, and joint ranges of motion. In this paper, the validity of this approach is assessed

Design optimization of a fully-compliant bistable micro-mechanism

In this paper, fully-compliant bistable micromechanisms were modeled using finite elements. This model was then coupled with an optimization program, allowing extensive exploration of the design space. The study revealed that the minimum layout size increases with the maximum force output.
