How to simulate a point-wise concentrate load traveling along a structure?

Now I'm working on the moving-load problems of the beams and plates. I want to use comsol to simulate a point-wise force or mass traveling along a beam, or traveling along a path on the plate surface, and explore the deformation of the beam and plate. I have read the post concerning this topic, but I still have no idea on how to deal with the concentrate moving load. Should I use the delta function? Is is possible to use comsol to consider the moving mass problem in which there exist the inertial interaction between the supporting structure and moving mass?
