Time, Distance, Speed, Acceleration and Jerk in Elevator Starting and Stopping

The paper studies in detail the relationship of, for one part, the nominal speed and maximum allowable acceleration and jerk versus, for the other part, the times and distances needed for starting and stopping the elevator cars. In the first part the physical and mathematical aspects of the problem are exposed, showing the substantial intervening facts and trying to convey a deep and intuitive grasp on the subject. The second part develops practical methods to calculate the starting and stopping times and distances by means of tables and graphic curves. Finally the relationship between the above calculations and real world conditions is discussed, including considerations for comfort.
