Challenge

The OEM wanted to develop efficient and futuristic RVs. The challenge was to create simulation-driven processes for the first time to be used in the RV industry. The project required complex modeling processes as RVs are built on a metal chassis with a composite superstructure of aluminum and wood. The project also encompassed the correlation of simulation results with tests.

Timetooth with its reputation for high quality simulations was chosen for the challenging project.

Advance Simulation Engineering

Timeline

September 2022 to January 2023

Correlation of the modal analysis results with the experimental results was done for the natural frequencies as well as the mode shapes.

Key Engineering Solutions

1. Structural analysis was carried out by applying road, snow and wind loads considering different parameters

2. Modal analysis of metallic structure, the wooden panels, and suspension was performed.

Solutions

Timetooth initiated the project with study of the design model shared by the client and meshing of the vehicle as per the standards. Operational loading conditions were defined jointly by the Timetooth team with the RV OEM team for the analysis. Structural analysis was then carried out by applying road, snow and wind loads considering different parameters. Modal analysis of metallic structure, the wooden panels, and suspension was also performed. Simulation results were interpreted to understand the natural frequencies and validate the model. Further experimental modal studies were executed on the vehicle. Correlation of the modal analysis results with the experimental results was done for the natural frequencies as well as the mode shapes. As per the assessment design direction was suggested to the client for improvements in local/panel mode in future.

Key Highlights

ROI for the client

The client received an evolved CAE driven process in addition to specific design improvements for the optimisation of RVs.
