I have some confusion with this calculation for my design.
I need to do the endurance testing for the pin which has to be loaded on flat face with the spring impact force, In this case how can I calculate the spring velocity, because in this case potential energy will be developed in spring & kinetic energy will be developed in bottom side face.
Now which mass I need to consider for KE calculation & then result velocity is applicable for Spring Object or Flat face compression.
please refer image for my design. In which Upside motion by cylinder & downside motion will be done by gravitational & Cylinder force for Top Half. but the Pin will move down by spring force..
