Push-up Bar Design & Analysis

Push-up Bar is gym equipment assisting in exercises involving pushing the whole body weight with your arms. It has a single rod structure along with two supportive beams on it's either ends in order to divide the force and let it to the ground easily.

I had ordered a similar styled push-up bar for the workout. I got it from an online website and when it arrived, it was made up of plastic which I knew but I was not sure about its durability. I assumed it will break within a few weeks.

Then thought of testing the push-up bar provoked me. I thought of testing it using my design knowledge. It was an interesting project to take up. I was really amazed by the result.

So, I made a 3Dmodel of the same in Solidworks by creating each part first and assembling them together. Then I moved to ANSYS for the structural analysis. Chose the appropriate material (PP plastic) from the library and imported the assembly. Defined the contacts and at last, the force under which the push-up bar will be performing.

I applied the force of 700N which is more than half the weight of the human. The push-up bar will actually experience the force which is more than the weight of the human using it. So, assuming the worst conditions I took the force to be 700N.

Solved the model and evaluated the Deformation result.

The deformation was 2.6mm which is quite inside the safe limit and hence this bar will be durable.
