Case Study: Tata Motors accelerates door seal simulation and design with Hexagon Marc

Door seal behavior prediction and enhancement

Tata Motors, a multinational automotive manufacturer, faced challenges in designing effective door seals due to the complex, nonlinear behavior of rubber materials. Their existing solver was ineffective, encountering convergence difficulties and making it hard to predict issues like water leakage and wind noise early in the design process. This prompted them to seek a solution from the vendor, Hexagon, utilizing their Marc simulation software.

Hexagon's Marc software provided specialized elements and automated contact analysis to accurately simulate the door seal performance. This solution enabled Tata Motors to run simulations four times faster, drastically reducing total analysis time from 155 minutes to just 40 minutes. The results showed good agreement with physical test data, allowing the team to identify key performance parameters early, which shortened the product development cycle and reduced costs.
