ST7-126.96.36.199 Modelling a Simple Double Pendulum
Strand7 can model kinematic motion with the Nonlinear Transient Dynamic solver. This Webnote covers the modelling of a simple double pendulum, which can be extended to modelling more complex mechanisms.
For this example, an arbitrary double pendulum is constructed. It is arranged to promote the chaotic behaviour inherent to this type of pendulum.
Coordinates are indicated at right.
Create a new model with Nmm units.
Create three nodes with the coordinates at right using Create/Node.
