Feder in Animation darstellen? Create a Spring in Animation mode?

Hallo,

Ich würde gerne eine flexible Feder in einer Animation darstellen.

Im Mechanismus- Modus habe ich das schon hinbekommen, würde das aber gerne auch in der Animation so darstellen und ein Video erzeugen.

Kann ich diese FEder aus dem Mechanismus Modus einfach kopieren, oder eine neue nach dem gleichen schema im Animations Modus erstellen?

würde mich über hilfe sehr freuen.

Gruß Tobias,

Hello,

how can i show a spring in Animation mode? Is it like to create an spring in Mechnism mode? or another way to create an spring in Animation mode?

i need help, thx.

Regards Toby

    Welcome to the forum, Tobias.

    The only successful version of an active spring in an animation sequence where regeneration is not required is to hinge the spring at 1/2 circle intervals. In other words, construct a spring in an assembly using semicircular segments.

    A user of the forum share this method:

    Dynamic Spring Model II.doc

    I tried to create a spring like that, but I didn´t fully understand the instuctions. Maybe someone can share a working file.

    Here some videos:

    I used the method in the attached file without a skeleton. This can be done in several ways but the idea is the same.

    Open the mechanism app and run the analysis.

    The links are bound to each other with an axis bound to a fixed plane; the 1st link is bound to the floor plane with a point, and final link is bound to the "cylinder" disk with a point. The connection is a cam just to provide animation. This could be done in many ways including a rack and pinion gear set.

    The assembly is free to float until the final link is connected. If over-driven, it can double on itself since there are 2 valid positions. An additional angle limited constraint set would solve this as well but not necessary if your range is limited.

    This is the only way I know that doesn't require regeneration in animation.

    Creo 2.0 full version attached.

    A curved spring can be constrained to a curve with a point, rather than constraining the axis to a plane. The idea is that each semicircle part has a path to follow.
