Case Study

Avishkar Hyperloop Designs an Hyperloop Tube, Chassis, and Aerodynamic Shell

Avishkar Hyperloop participates in the annual European Hyperloop Week (EHW). The categories change every year and are judged by the design, simulations, manufacturing, and the overall engineering of the product. It is nearly impossible to accurately calculate things such as stress, deformation, and pressure contours with hand calculations. Ansys is a necessary tool for the Avishkar Hyperloop team to simulate loading conditions and develop a lightweight chassis and extremely thin aerodynamic shell. Saving weight enables usage of less propulsive and levitating power and, hence, a lightweight pod and thin shell.


The propulsion, braking, and levitation systems are mounted on the chassis and each of these systems exert forces that can deform it. It is very important for the team to create a chassis design that will not deform while being as lightweight as possible.

The aerodynamic shell design need to be extremely lightweight. The lighter weighted the shell is the lesser power is required from the batteries for levitation and propulsion. This required the team to optimize the shape and thickness of the shell.

Engineering Solution

The team created a preliminary shape of the chassis and applied the forces, displacement constraints, and boundary conditions so deformation and stresses could be simulated. Once a basic structure for the chassis was finalized, topology optimization helped remove any unwanted material and ensure adequate stiffness of the structure. Overall, the mass of the chassis was optimized by more than 60%.

A similar methodology was followed for the aerodynamic shell.


Ansys was a crucial tool for designing and optimizing the chassis and aerodynamic shell of the hyperloop pod. Specifically, they reduces the mass of the chassis by more than 60%. Similarly, the drag for the shell after simulation came out to be less than 0.2, thereby reducing the drag force by a great degree. Tests done with Ansys were also validated with a scaled down version of the shell in a wind tunnel, adding to the engineering feel for team members.
