adaptive curved spring in SolidWorks
define the curvature of the spring in the context of an assembly and animate.
-
Step 1: model a point
point is a mere reference geometry. insert it in an assembly twice. make one end fixed. create a sketch in the context of the assembly for positioning of the other point.
start modeling the spring top-down.
-
Step 2: draw a line for the sweep
a line will be the profile of the surface sweep. twist control with 9 revolutions.
-
Step 3: create the 3Dpath
start a 3Dsketch with the intersection curve of the two surface bodies. finish with the swept boss with the 3Dcurve for its' path.
-
Step 4: path mate definition
-
Step 5: change position of point on path
-
Step 6: ...and animate with motion study.
