Speed Changing Oscillator


image

This oscillating mechanism changes speed during an oscillation. A rotary input will normally change the speed of the oscillator but the added Whitworth quick return mechanism makes it change in two ways.

Front End Loader


image

This is a model of a front end loader bucket mechanism. I never actually tried to use “Always Manual” inputs during a video export, but it worked fine even with the animation running slower than real-time.

Box Transport Mechanism


image

A user wanted to build a box transport mechanism but the design used a problematic linkage; the simulator can’t simulate some type of mechanism. This is a redesign of that mechanism.
