thank you for your help so far... but i get always the same mistakes
after entering the solution of DH ...  (<<1>> of piecewise is not a
list of pairs) what is wrong?

In[35]:= ex2piec[Integrate[model27SA, t]]

During evaluation of In[35]:= Piecewise::pairs: The first argument \
\[Piecewise]<<1>> of Piecewise is not a list of pairs.

Out[35]= Piecewise[Most[\[Piecewise] {
    {0., t <= 40.},
    {560.- 28. t + 0.35 t^2, 40. < t <= 50.},
    {935.- 43. t + 0.5 t^2, 50. < t <= 55.},
    {-123.75 - 4.5 t + 0.15 t^2, 55. < t <= 140.},
    {-6983.75 + 93.5 t - 0.2 t^2, 140. < t <= 145.},
    {-10137.5 + 137. t - 0.35 t^2, 145. < t <= 150.},
    {-13512.5 + 182. t - 0.5 t^2, 150. < t <= 155.},
    {-5103.75 + 73.5 t - 0.15 t^2, 155. < t <= 245.},
    {3900., \!\(\*
       TagBox["True",
        "PiecewiseDefault",
        AutoDelete->False,
        DeletionWarning->True]\)}
   }]]
