Ramp Motion-Law

Ramp Cam-Law, Motion-Law

Motion Description

 The Ramp. has three phases: Phase 1: Acceleration : first ½ wave of a Sine function (see Segment-Parameters) Phase 2: Zero Acceleration : Constant Velocity Phase 3: Deceleration : last ½ wave of a Sine function : (see Segment-Parameters) You can design an Asymmetric Segment, in which the Acceleration phase is longer or shorter than the Deceleration phase. A motion with continuous Velocity and Acceleration, from start to end, The Jerk is finite at its start and end.

Motion-Values

You CAN specify the:

 Start-Position   The Start-Position usually flows from the End-Position of the End-Position

You CANNOT specify the:

 Start Velocity & End Velocity Start Acceleration & End Acceleration Start Jerk & End Jerk

Segment Parameters

 Start-Fraction × 100 = % of Segment-Width to accelerate from zero-velocity* to maximum-velocity End-Fraction × 100 = % of Segment-Width to decelerate from maximum-velocity to zero-velocity** Start-Fraction + End Fraction 1 Constant-Velocity % = 1- Start-Fraction – End-Fraction * assuming Start-Range is zero ** assuming End-Range is zero

Segment-Range

 Start-Range - remove the start of the Ramp Motion-Law End- Range- remove the end of the Ramp Motion-Law 0 ≤ Start-Range < End-Range ≤ 1
