Analysis of Rolling Resistance of wheel
Budget: ₹1,500 – ₹12,500 INR
I. Methodology:
1. 3-dimensional Finite Element Modeling (Dynamic simulation) of Tyre (Radial) needs to be performed which should be validated using Simulink. Different working conditions need to be considered by varying the parameters like inflation pressure and load on wheel. The simulation needs to performed only on one wheel and terrain to be taken as sand. The properties of sand may be considered accordingly.
2. The tyre assembly needs to be modeled in Solidworks software. The dimensions of te tyre to be considered as per the size: 235/65R17. The model should clearly show tire tread. Tyre being a hyperelastic material need to be assigned a model like Neo-Hookean and Ogden. Free rolling simulations are required to be performed. The tyre is to be shown running to some distance say for few seconds. The sand model to be given dimensions much bigger than the tyre say 3 meters x 1 meter x 1.5 meter (l x w x h). Please note that only SI units to be used like Meter or millimetre, Kg, Newtons, Pascals etc.
3. Consider any SUV weighing between 1800 to 2000 kg
i. Tire size: 235/65R17
ii. Tire diameter is 736.6 mm
iii. Surface to be considered as sand
4. The simulation approach should be as follows:
i. Dynamic Simulation to be performed in Abaqus or Ansys Workbench with given combinations of data-sets as given below. Please don’t use student version
ii. The tire should be Hyper-elastic model: Neo-Hookean & Ogden
iii. The tyre pressure to be considered are (P): 25 and 30 psi for 2 cases respectively
iv. The velocity to be considered (V): 20 km/hr
v. Load on wheel (W): 600 kgs
vi. There should be 08 iterations with each combination of Neo-Hookean model and Ogden model as given below:
a) P: 25; V: 20; W: 600
b) P: 30; V:20; W: 600
c) P: 25; V: 20; W: 700
d) P: 30; V: 20; W: 700
The difference in the two results to be highlighted.
5. Graphs to be generated for ‘”Rolling Resistance vs Tire Inflation pressure’, ‘Tire deformation vs wheel load’ and ‘Vertical load vs Tire sinkage’
6. Simulink simulation to be used for validation of only one case of FEA analysis carried out i.e. for vi. (a) above.
II. Deliverables:
1. The project deliverables should be in the form of simulation results, graphs generated, report, animation of simulation.
2. The executable / implementation file developed in both FEA and Simulink to be generated for handing over to me.
3. The designer to explain the method, steps and types of simulation adopted in a short video.
4. The designer to attend queries / doubts after submission
Note: Any data inputs or literature required for carrying out the work may be taken from me.
