### Olympic Weightlifting Gets Drop Tested with SOLIDWORKS Simulation

Monday, August 15th, 2016

## Ever wonder why rubber weights are used in Olympic weightlifting, but iron plates in most gyms?

We did. So, we looked into it.

The World’s greatest athletes demonstrate what it means to push the boundaries of human potential at each Olympic Games. In Olympic weightlifting, for example, new records are being set every year. Much is said about the athletes and how they challenge their limits to achieve new heights, but what about the equipment?

### Weightlifting Equipment

• Has it always been the same?
• What kind of stress occurs when the bar is dropped?
• How could pushing the boundaries of design enable athletes to achieve more?

At GoEngineer, these are the kinds of questions that keep us up at night.

Here’s what we found;  changing the material of the weights, changed the sport of weightlifting.

See our Simulation FEA Drop Test

Weightlifting has been an Olympic event since the very first Olympics in Athens in 1896. Back then, the bar and the plates were made out of iron. The rules required athletes to gently return the weights to the ground. This obviously wasn’t possible when an athlete was going for a max effort lift, and would miss.

### SOLIDWORKS Simulation – Frequency Analysis of Tensioned Guitar Strings

Monday, February 1st, 2016

SOLIDWORKS Simulation is powerful.  Using this tool, I will demonstrate the correlation between SOLIDWORKS Simulation FEA and the solution of a theoretical equation through the analysis of a guitar string.

Setup
In this setup, a single guitar string is restrained on both ends. Restraining the string allows it to reach fundamental frequency, which is 1 half wavelength along the length of the string.

The setup will utilize beam elements for the string as it is long and thin. One end will be fixed in the radial, axial, and circumferential directions, while the other end is fixed in only the radial and circumferential directions. On the free end, a variable force will be applied to observe the change in fundamental frequency on the string.
