With the contacts defined, proceed further with the model analysis.
To use the caulk gun, you hold the handle and pull the trigger. From the static analysis point of view, the components are under force and deform before the plunger head moves the bottom of the tube. We can reasonably assume that the components deform relative to the main frame. As such, we can apply a:
- Fixed constraint on the main frame edge [12]
- Force on the handle [13]
- Force on the trigger [14]
- Force on the plunger head [15]
- Force on the ring [16]
The tube is held in place by the front frame, ring, and plunger head. When the force from plunger head is large enough, the bottom of the tube moves further into the tube and pushes caulk out of the nozzle. For the static analysis, we simulate the instant at which the force on the tube bottom is in equilibrium with the tube resistance. Before the tube bottom moving, we examine the stress and deformation of the whole structure and components.
