SHM stands for simple harmonic motion. Simple harmonic motion is when you have an object that has a periodic motion (motion repeats after a period of time), and the unbalanced force (and so acceleration) is proportional to the displacement of the object. The acceleration acts in the opposite direction, i.e. tries to bring it back to the equilibrium position. An example is a pendulum. I believe that this is described mathematically by a second order differential equation, but I've not looked into that yet so I can't help you there I'm afraid.
