The first mechanism is a six-bar linkage with scissor kinematics. The second multi-bar system is a parallel linkage, or more specifically a parallel-crank linkage, which can also be interpreted as a degenerated version of a six-bar linkage of the same type as in the first case. In both cases, a kinematic synthesis was used to find a solution, and then a force analysis was carried out. From that, the necessary torques for both of the linkages can be determined, for example. Additionally, it is shown how to use scripts to implement forces that depend on the ladder position (steps extended or retracted).
Foldable step ladder for a mobile home with ASOM
Using the example of a two-step folding ladder for a mobile home, it is shown how two systems can be organized in different folders in the element tree for the purpose of a direct comparison.
