The linkage geometry can be created within Dynacam 10 Plus and analyzed for its kinematics. It will also design a fourbar or sixbar linkage/slider follower train, driven by the cam. This new program has all the functionality of Dynacam 10 and adds the ability to import a cam profile and reverse-engineer the cam by fitting B-spline or other functions to the data. The Hertzian surface stresses in cam and follower due to the dynamic loads plus any user-specified dynamic external load function and the weight of the follower train are calculated. The combined torque of any number of cams on a common camshaft can also be determined. Data necessary to the sizing of a flywheel for any selected coefficient of fluctuation are calculated. All calculated kinematic and dynamic parameters can be plotted, and all data may be printed to the screen, or to a disk file suitable for import to a spreadsheet program.
The cam profile is calculated and a cutter-coordinate file can be exported in Cartesian coordinates in a form that can be imported into Excel, Autocad, Pro-Engineer, Solidworks, Unigraphics, and other CAD packages. Polydyne and splinedyne cams can be created. Dynacam 10 also provides five different dynamic models (1- and 2-mass) for the estimation of true dynamic force and vibration of the follower, using a 4th-order Runge-Kutta algorithm. If the user supplies estimates of the lumped mass, spring constant, and damping of the follower system, the program will calculate the kinetostatic follower force and camshaft torque. The pressure angles and radii of curvature are calculated for any user-selected base or prime circle diameter. External force-time loading functions can be applied to the follower. General polynomial functions and B-spline functions can also be designed using any user-specified set of boundary conditions to create custom cams that use multiple, single, or no dwells. All of the standard, acceptable, double-dwell cam functions are included such as modified trapezoidal, modified sine, cycloidal, 345 polynomial, and many others. Roller and flat-faced translating followers can be accommodated on radial cams and roller followers on barrel and linear cams. Radial, linear, and barrel cams with either translating or oscillating followers can be designed. This program solves the kinematic and dynamic equations for cam-follower systems.
DRIVE SYSTEM DESIGNER WINDOWS
It has been completely rewritten to be compatible with Windows 10. Is used by many companies around the world to design commercial cams and is available in two versions.
