Reciprocating Roller Cam

This cam is set up as a double dwell cam with a cycloidal rise and fall.

Follower displacement	var a=1; // start of rise (in radians) var b=2; // start of dwell var c=4; // start of fall var d=5; // start of dwell var s0=4; //initial dwell displacement var s1=6; // final dwell displacement var u = x/(2PI); x=(u-floor(u))2*PI; if (x<a) return s0; if (x<b) return Cycloid(a,b,s0,s1,x); if (x<c) return s1; if (x<d) return Cycloid(c,d,s1,s0,x); return s0;

Different transition functions can be used.

Try replacing Cycloid with anyof the following:
ModifiedSine, ModifiedTrapezoid, DoubleHarmonic, Polynomial345

Or write your own displacement function from scratch.
