Variable Pitch/Rate Compression Springs with ASD7
Our Advanced Spring Design 7.0.13 software includes programs
for compression springs in series as well as in parallel. This allows for spring designs which change
in stiffness as the loads increase.
Variable pitch springs have an initial stiffness until those
coils with the smallest pitch begin to go solid. Here’s an example along with a plot of the
load/deflection curve.
Nested springs of different lengths can also be used to change
the stiffness as the load increases. The
longest spring will resist the load by itself until it deflects to the length
of the next longest spring and then both will be engaged.
Here is an example of three nested springs along with a plot
of the load/deflection curve.
If you haven’t seen this software in action, download a free
trial from our web site http://www.uts.com/Freetrial.asp and/or
call us to schedule a free orientation via GotoMeeting.
