Challenge

The client wanted to develop aluminum LPG cylinders to replace steel cylinders. Aluminum being lightweight would allow easy portability to the user, distributor and manufacturer.

 

Timetooth was given the challenge to design and develop an aluminum alloy LPG cylinder conforming to ISO 20703:2006 standard.

Service Area

Advanced Engineering Simulations

Timeline

April 2021 to September 2021

Timetooth leveraged non-linear quasi static and non-linear dynamic analysis to predict structural stresses and deformations.

Engineering Design Analysis

1. Nonlinear explicit FE analysis was done. Tools used were Altair Hyperworks.

2. The ISO standards were studied and various tests were mapped to simulation boundary conditions.

3. Tests such as yield pressure, burst pressure, drop test, volumetric expansion and mechanical properties in different loading conditions were conducted.

Solutions

Timetooth started the project by modifying the base design of steel cylinders for consideration of aluminum fabrication. The ISO standards were studied and various tests were mapped to simulation boundary conditions. Timetooth leveraged non-linear quasi static and non-linear dynamic analysis to predict structural stresses and deformations. Tests included yield pressure, burst pressure, drop test, volumetric expansion and mechanical properties in different loading conditions. The results were interpreted and design modifications were shared for a high performance product.

The client implemented the design suggestions, fabricated the prototype and executed the tests. The prototype cleared the acceptance criteria of the tests.
