Screw-clamp system · 模型 277093
Made with Autodesk Inventor 2014 as a Stress Analysis (FEA) for an assemble. The assembly is a typical part from a clamping device. A „Part” is clamped in a jig device in order to be manufactured. The force is applied by a screw at a value of 1800 N (about 405 lbs). As usual, if you work with Inventor you will find the .iam and .ipt fils so you can download them to enter Environments / Dynamic simulation and see for yourself what's happening. You will have all the settings at your will, so you can change everything. However, if you want to start from component to assembly, and then to Stress analysis read next. Compare your settings with the downloaded iam or with included report file (Screw-clamp system - Stress Analysis Report 19-Jul-15.zip). The next explanation are based on the supposition that you use Autodesk Inventor (2014 or up), but the similar situation should apply for other CAD software. The assembly is constrained from its components (see the picture Screw-clamp system - 01.jpg) to have a functionality as in picture Screw-clamp system - 02.jpg. A special attention should be done to the tangent constraint as in Screw-clamp system - 03.jpg. In order to make the simulation, the action of the screw was replaced by two opposite forces of 1800 N each. Having the assembly enter Environments / Stress Analysis an create a new simulation (named here as „Assembly Simulation”) taking care to change the setting „Bonded” with „Sliding/No separation” in the dialog box. Verify materials assignation (Steel for all), fix the bottom face as in Screw-clamp system - 08.jpg, and place the two opposite forces like in Screw-clamp system - 08.jpg and ...- 09.jpg. Apply the tool Simulate and wait to run. Check the item contacts in the browser. You will see that all contacts are automatically assigned as „Sliding/No separation”. You have to change three of them in „Bonded”. They are the contacts between the „Clamp” and „Pin - short”, „Fork” and „Pin - long” and one from the three „Support” and „Part”. Now activate again the Simulate tool in the Solve tab and watch for results. Activate Animate/Play to see the moving parts. This moving is exaggerated. If you want to see the real moving, change the „Adjusted x1” to „Actual” in the Display tab. The colors show the amount of stress from blue (low) to red (high), and the stress is presented in MPa (Megapascal, like pressure). 1 MPa is about 0.1 Kgf/mm². The picture Screw-clamp system - 12.jpg sh...
