BETTER PRODUCTS THROUGH VIRTUAL PROTOTYPING & SIMULATION
Titanium Mountain Bike Frame
We have developed a Titanium bike frame that will be fabricated using additive manufacturing. We optimized the bike frame in ANSYS for strength and stiffness. The titanium bike frame will weigh the same or less than the best carbon fiber bikes on the market, but will be incredibly tough and durable. Able to withstand even the most grueling torture tests and take an incredible amount of punishment without damage. Our Titanium frame is designed for a 300 pound rider and a 4g load, unlike its carbon-fiber counterparts, it will not splinter or crack. The titanium frame is built to take abuse and absorbs energy considerably better. Additionally, the frame is encapsulated in a hybrid composite material and covered with a protective skin making the frame immune to damage from impact due to rocks and trees.
Specialties To Include:
ANSYS, ANSYS CFD, ANSYS CFX, ANSYS Fluent, ANSYS FEA, ANSYS FSI, Finite Element Analysis, Computational Fluid Dynamics, Structural Analysis, Conjugate Heat Transfer, Vibration, Fatigue.
Using SpaceClaim to create a surface model and ANSYS mechanical we analyze multiple configurations and different architectures of the titanium bike frame. We want the lightest possible bike frame with the highest possible stiffness with a 1.5 factor of safety. We varied the thickness of different structural members of the frame and created a table of weight versus deflection to assist us choosing the optimal configuration and architecture of the frame.
We varied the thickness of the structural members as well as the spacing of the structural ribs and calculated the weight, stiffness and safety factor.
The size of the lightening holes was varied to achieve the stiffness, weight, and safety factor goals. From this we can create a table of hole diameter, weight, stiffness, and safety factor.
We went through hundreds of different design iterations varying the thickness, spacing and architecture of the frame. We applied stiffening ribs in varying locations and thicknesses to achieve the optimal design with less than 2mm deflection, 1.5 factor of safety and 2-pound total weight or less.
