... and demonstrates that the conjugating tooth profile should be a three-dimensional surface because of the cup deformation. The use of spur gears on both flexspline and circular spline will cause excessive interference and excessive deformation will become necessary to overcome the interference. Since no-load...

...Un-Koo Lee; Seong Bae Jang; Seong S. Cheon In this paper, a subframe type fuel tank module was proposed and evaluated to increase the vehicle safety and the design flexibility against rear crash of automotive vehicles. In order to minimize the deformation of the fuel tank during rear crash, crash...

... deformation analysis, which are strongly coupled. One could rely on standard 3D contact detectors and standard 3D finite element analysis (FEA) to simulate the two steps. However, since snap-fits are slender, 3D FEA tends to be inefficient and slow. On the other hand, one could rely on an explicit 1D beam...

... of their complicated deformation pattern. The behavior of a bistable compliant mechanism, in general, is highly nonlinear. Using combinations of such nonlinearities to capture the behavior of multistable (more than two stable positions) mechanisms can be quite challenging. To determine multistable behavior, our...
