In the model, the pin end of the trigger contacts the actuator. Separation Contact The Separation contact allows separation between parts but prohibits part penetration. You use Bonded contacts to simulate these joints in the simulation. In the model, the Front Frame-Main Frame and the Front Frame-Handle interfaces are weld joints, as shown in the following image. Typical Bonded contacts include weld or glue joints between two parts. The following sections detail each type of contact used in the analysis of the caulk gun assembly.īonded Contact The Bonded contact simulates rigid bonding of faces to each other.

The Edit Automatic Contact or Edit Manual Contact dialog box displays and shows the available contact types:
In the browser, right-click a contact and select Edit Contact. As you create or edit contacts, they are added under existing contact type nodes or to newly created nodes. Note that we exclude the following components from the simulation: Caulk Tube Actuator Spring (not modeled, but simulated with Spring contact) Lock Spring Lock Ĭontact Types Inventor Stress Analysis provides the following Contact types: Bonded Separation Sliding / No Separation Separation / No Sliding Shrink Fit / Sliding Shrink Fit / No Sliding Spring In the Stress Analysis browser, expand the Contacts node to view the contact types currently in use for the caulk gun simulation. Expand Caulk Gun.iam in the Stress Analysis browser. Stress Analysis commands populate the ribbon. On the Environments tab, Begin panel, click Stress Analysis. On the ribbon, click the Environments tab. To enter the Stress Analysis environment: 1. At this instant, just before caulk exits the tube, the assembly is in static equilibrium. This simulation investigates when the trigger is pulled and the pushing force on the bottom of the caulk tube is about to overcome the internal tube resistance. Several operational scenarios can exist for the caulk gun, but we chose to simulate the assembly in a static equilibrium state. Assembly Simulation The caulk gun is an assembly which consists of several parts, some of which can move. The tube is held in place by a ring at the end of the caulk gun. The plunger head pushes the caulk tube bottom.ĥ. The actuator tightly engages the plunger and pushes it forward. The pin end of the trigger pushes the actuator forward. User holds the handle and pulls back on the trigger. How a Caulk Gun Works We considered the following mechanics of the caulk gun when creating the simulation. In Inventor, navigate to Caulk Gun.ipj and make it your active project.

Open the Assembly A model of a caulk gun illustrates different contact types and how to use them in a static, structural analysis. The contacts have already been created, either automatically or manually, in the model.
This skill builder presents an assembly modeled with many of the types of contact available in Inventor 2010 Stress Analysis. There are several different contact types you can use to simulate the physical behavior of an assembly. Without contacts, parts do not interact with each other in the simulation. Contacts can simulate interaction between bodies that separate or come into contact during loading. Contacts transfer load between parts while preventing parts from penetrating each other. Overview In the structural analysis of an assembly involving multiple parts, you create contacts to define the relationship between the parts.
