I am trying to model a crane as a sdof so firstly by means of a mass spring system in order to get its displacement (vibration) upon an impulse (load).
I have an equation (newtons law) for it with a mass equal to 177046.4 and stiffness of spring equal to 1.0513x10^13. The max load the crane can take is 10ton, but I have been advised that the impulse would be anything between 1-3 tonnes in magnitude.
Not sure how to model this to then also get a plot of vibration (displacement of crane vs time).
Thanks in advance.

Hello
You can refer to the sample examples available in MATLAB to model Mechanical systems. It includes examples corresponding to Mass-Spring-Damper systems modelled in both Simulink and Simscape which can helpful in your case.
The documentation link corresponding to examples related to modelling Mechanical systems is available below:

I hope this helps....
