xm(t) - position of the master as a function of time (i.e. the master motion profile) xs(xm) - position of the slave as a function of position of the master (i.e. a cam) The slave acceleration - second derivative of its position over time xs''(t)=[xs(xm(t))]''=[xs'(xm(t))*xm'(t)]'=xs''(xm(t))*(xm'(t))2+xs'(xm(t)*xm''(t) However, if one wanted to calculate an instantaneous acceleration of the moving slave then it'd take few past positions to be collected and the derivative calculated numerically directly from the position values. |
