Interval calculation is used to find an envelope of transferfunctions for mechanical systems modeled with ... analytically. The exact mechanical solution set is given in Figure 2. It is called mechanical exact solutionset. The hull of this set (which is an interval vector) has also been drawn. The mechanical exact ... solving linear systems of interval equations. We will thenintroduce a new formulation of the problem, based on interval parameters which isadapted for the modeling of mechanical systems. An adaptation...
