Folding Umbrella Framework Destruction Force Analysis Based on Virtual Prototype

Failure analysis is important for the safety design of the folding umbrella. The failure point is found on certain location after large amount of samples statistics. In order to verify this problem, apply SolidWorks to finish the umbrella framework model, import the model into ADAMS. Then the experiment is conducted, the push force on the umbrella piston which adds to the mechanical model is measured through Gravity Sensor. The dynamic simulation of umbrella framework is discussed by using ADAMS. The simulation result shows the failure point we found is accurate. Since the destructive force on umbrella is diversity and uncertainty, further studies are necessary for this subject.
