Program SLIDER by R. L. Norton

This program solves the kinematic and dynamic equations for any fourbar offset slider-crank linkage. The user needs only to input the crank and conrod length, the offset, and the location of one coupler point to calculate all kinematic parameters for any of: one input link position with given angular velocity and acceleration, constant angular velocity of the input link, or constant acceleration of the input link. The linkage will then be drawn and animated and its coupler curve shown.

If the user also supplies mass property data for each link and the values of any external forces or torques applied to the links, the program will calculate the kinetostatic forces and torques that result. Kinematic and dynamic parameters can be plotted as either cartesian or polar plots, and all data may be printed to the screen, a printer, or a disk file that is suitable for import to a spreadsheet program. Data necessary to the sizing of a flywheel for any selected coefficient of fluctuation are calculated.
