Basically it is sort of a rocket equation but only for y´´>0. For the other half of the cycle m(y(t)) depends in the value of y(t). Considering F(y) which discribes the propulsion it is a self oscillatory system with internal excitation. I managed to solve it in mathlab (simulink) but I can not...
Hi, can anybody give me a hint on how I get Mathcad to solve an equation like m(y(t))*y''(t)=F(y). The problem is that m(y(t)) depends for a certain time on the value of the last amplitude and therefore mathcad has to remember this value within the solve block somehow. Thank you
