ASOMmini Example “Umbrella”

This example video shows how a typical umbrella can be modeled and analyzed kinematically in ASOMmini. The umbrella is opened automatically by a pressure spring, which is installed between the two movable sliders.

The manual force at the lower slider is displayed as a diagram, as are the joint forces at some critical rotary joints. All joint forces are also displayed as directional arrows with time-varying lengths on the canvas.

It is demonstrated how all of the displays react in real time to manipulation of, for example, the characteristic of the pressure spring. In addition, in this example, some links have been hidden and replaced by imported DXF drawings, which are then moved along with the corresponding kinematic elements and thus give the parts of the umbrella frame a more realistic shape.
