In this example, a complete force design for a spindle drive to actuate a tailgate is presented. For this purpose, holding forces are computed under different ambient conditions such as inclination changes, snow loads, friction, clutches, overload cases, safety margins, efficiency factors, etc.
To correctly observe also direction-dependent influences, the complete opening and closing sequences are evaluated in real time at the same time using compressed time simulation.
The spindle drive consists of a fully configured spindle and two fully configured springs as energy storage components (one main support spring and one pop-up spring).
Everything presented here for a simple hinge can easily also be applied to an arc hinge, a four-bar system, or a different multi-bar system.
