However, the envelope method cannot predict the groove bottom profile accurately because it does not ac ... [J. Mech.

The original design consists of two identical parts assembled at right angle with respect to each other. The single piece part can be produced from planar materials; thus, it has the advantage of easiness in manufacturin ... [J. Mech.

The robots must be small, reliable, energy efficient, and capable of ca ... [J. Mech.

This new approach is based on the nullspace of the kinematic constraint matrix computed from the mechanism graph or its adjacency matri ... [J. Mech.

New approaches are required to generate alternative solutions at the function and behavior level as well as to ease the computati ... [J. Mech.

Assembly constraint features serve to provide this DOF removal, so their locations and orientations greatly affect the quality of an assembly as measured by i ... [J. Mech.

Smith<br/> A number of cognitive skills relevant to conceptual design were identified previously. They include divergent thinking (DT), visual thinking (VT), spatial reasoning (SR), qualitative reasoning (QR), and problem formulation (PF). A battery of standardized tests is being developed for these design ski ... [J. Mech.

Philip Chen<br/> Model uncertainty often results from incomplete system knowledge or simplification made at the design stage. In this paper, a hybrid model/data-based probabilistic design approach is proposed to design a nonlinear system to be robust under the circumstances of parameter variation and model uncertain ... [J.

Talbot, Ahmet Kahraman, and Avinash Singh<br/> In this paper, results from an experimental study on power losses of planetary gear sets are presented. The experimental setup includes a specialized test apparatus to operate a planetary gear set under tightly controlled speed, load and oil temperature conditions, and instrumentation for an accurat ...

In modern engineering design, this task is often performed by a computer simulation tool such as finite element method (FEM). This type of computer simulat ... [J. Mech.
