Watch this video for using polynomials.

Polynomial OK Button

Click this button when all the constraints are entered and ready to use in the kinematics.  If the coefficients have not been computed, they will be computed before the form closes.

 

Save Constraint Button

After one set of constraints have been entered, or, matched, click this button to save the constraints to the Polynomial Constraints table below.

 

New Constraint Button

Click this button when a new set of constraints are to be entered.  This will blank out the edit boxes for new data.

 

Match All Button

This button will place all the ending parameter values of the previous segment in the relevant edit boxes.  HINT: to save time, click this and then alter the value, or values desired.  NOTE: Matching values is only available for the beginning of the segment.

 

Ending Cam Position Prev Seg

This is the value of the cam position for the previous segment.

 

Table of Entered or Matched Constraints

Each set of constraints will be listed in this table.  To edit a constraint, click on the row of that set and all the values will be shown in the edit boxes above.

 

Coefficients of the computed polynomial

If the Compute Coefficients button is clicked, the coefficients for the polynomial will be computed and shown here.

 

New Polynomial Button

To begin a new polynomial, click this button.  All the edit boxes will be blanked for new data.

 

Cam Position

This is the cam position for the set of constraints being entered, or matched.  The constraints are based on the segment cam positions; therefore, the beginning cam position will always be zero and the ending cam position will be the ending segment amount.  For example, if this cam segment is 45 degrees, the the beginning cam positin will be 0.000 deg.  Matching of constraints will only be allowed at cam position of 0.0000.

 

Disp. Constraint

Enter here the value of the displacement for the cam position above.  If this is a matched value, it will be the ending displacement of the previous segment.

 

Ending Disp Prev Seg

This is for information only.  It is the value of the displacement at the end of the previous segment.

 

Velocity Constraint

Enter here the value of the velocity for the cam position above.  If this is a matched value, it will be the ending velocity of the previous segment.

 

Ending Velocity Prev Seg

This is for information only.  It is the value of the velocity at the end of the previous segment.

 

Accel Constraint

Enter here the value of the acceleration for the cam position above.  If this is a matched value, it will be the ending acceleration of the previous segment.

 

Ending Accel Prev Seg

This is for information only.  It is the value of the acceleration at the end of the previous segment.

 

Compute Coefficients Button

This button will compute and show the coefficients for the constraints.

 

Cancel Button

Cancel the form and dies not change any of the polynomial values.

 

Help Button

This will bring up the help for this topic.

 

Undo Button

Click this button to undo the edits made.

 

Delete Button

Click on a constraing in the table and click this button and it will delete all of the row in the Polynomial Constraints table.

 

Jerk Constraint

Enter here the value of the jerk for the cam position above.  If this is a matched value, it will be the ending jerk of the previous segment.

 

Ending Jerk Prev Seg

This is for information only.  It is the value of the jerk at the end of the previous segment.
