G1 CAD Simulation

Discover the pinnacle of performance and precision at Getail Design, where we redefine the standards of simracing excellence. Embracing the ethos of lightweight design, our G1 HUB epitomizes unparalleled strength and durability, even under the intense demands of direct drive steering wheels.

At the heart of our innovation lies the meticulous selection of materials. We've chosen 6061 aluminum, a premium alloy celebrated for its exceptional stiffness-to-mass ratio. This deliberate choice, combined with our engineering prowess, has resulted in a groundbreaking achievement: the G1 weighs in at a remarkable 116g, setting a new benchmark in lightweight construction.

To underscore the structural integrity of the G1, we're proud to share insights from our rigorous testing protocols. Transparency is paramount to us, and we invite you to explore the results of our comprehensive structural tests, affirming the unwavering quality and performance of the G1 HUB.

Here are the results of four tests done with Autodesk Fusion, these tests are also analyzed in the Let's GO RACE reviews.

 

We do not recommend trying these tests at home since you risk breaking and damaging the Direct Drive wheelbase and steering wheel as well as getting injured.

 

 

USEFUL INFORMATION

SIMPLIFIED:

We have simplified the hub for the simulation to get more realistic results with fewer variables.

 

 

SAFETY FACTOR:

It is an Autodesk fusion parameter that describe the ratio of the maximum strength of the material to the actual stress in part. Safety factor = material strength / actual stress The scale goes from 0 (broken) to 15 (over engineered). Values from 0 to 3 are synonymous with a possible breakdown or permanent deformation. Values equal to 3 or higher are not subject to breakdown within the parameters of the calculation.

 

 

CONSTRAINS:

-Fixed constrains are an added pieces that in the simulation isn’t moving.

 

 

TESTS

STRAIGHT FORCE HUB SIMULATION

DESCRIPTION: We placed the constraints in one side of the mounting holes to simulate as if you were hanging on the hub.

SPECS: Fixed constrains on one side. 275N force is applied to the other side of the constrains.

RESULTS: the hub can hold a weight of 28kg hang on it. SF=3,04 Max displacement=0,48mm

 

 

STRAIGHT FORCE PILLAR SIMULATION

DESCRIPTION: We placed the constraints in both sides of the mounting holes and a force in the middle of the hub to understand how much force the pillar can support.

SPECS: Fixed constrains on both sides. 2000N force is applied at the center of the hub.

RESULTS: The pillar can hold easily a weight of 203kg hang on it. SF=6,84 Max displacement=0,036mm

 

 

TORSIONAL HUB SIMULATION

DESCRIPTION: We placed the constraints in one side of the mounting holes and a torque in the pillar to simulate as if you were trying to keep the wheel straight with a torque of 70NM.

SPECS: Fixed constrains on one side. 70NM torque put on the center of the pillar.

RESULTS: The hub can hold a torque of 70NM. SF=3,18 Max displacement=0,383mm

 

 

TORSIONAL PILLAR SIMULATION

DESCRIPTION: We placed the constraints in both sides of the mounting holes and a torque in the pillar to simulate so we can understand how much torque the pillar can support.

SPECS: Fixed constrains on both sides. 70NM torque is applied at the center of the hub.

RESULTS: The pillar can hold easily a torque of 70NM. SF=6,21 Max displacement=0,025mm
