Vehicle mechanisms require careful analysis. Our solutions analyze components like powertrains and convertible roofs, incorporating linear and nonlinear effects.

The automotive body is vital for integrity, noise reduction, and safety. SIMULIA’s Abaqus FEA suite integrates Body in White (BIW) and Trimmed Body analysis, streamlining workflows for crash safety and stiffness.

In electric vehicles, batteries act as modern fuel tanks, storing energy to address range concerns while ensuring safety. Dassault Systèmes offers comprehensive battery solutions, including BIOVIA for chemistry modeling to enhance battery longevity and CATIA libraries for 1D simulations of cells, modules, and packs. This system-level approach integrates the aging, thermal, and electrical characteristics of cells.

The electric drive is essential for vehicle electrification and integrates into the electric powertrain and vehicle architecture. Early understanding of system interdependencies through Model-Based Systems Engineering (MBSE) is crucial for optimizing performance and balancing design objectives, aligning system-level and physics-based simulations.

The brake system is essential for vehicle safety and performance, ensuring reliable, durable, and efficient operation. Customers expect quiet operation and predictable maintenance, making effective design critical.

Designing energy-efficient vehicles involves addressing conflicting goals while meeting stringent environmental regulations. Effective thermal management is crucial for reducing emissions and enhancing vehicle performance, contributing significantly to compliance with evolving standards.

The success of a vehicle program hinges on selecting the right concepts for development. As the number of models and architectural options increases, decision-making becomes complex for concept engineers facing tight timelines and conflicting requirements. Insufficient collaboration among architects and domain experts often results in isolated efforts and suboptimal outcomes.

Effective powertrain design is essential for a vehicle's reliability, durability, efficiency, performance, and safety. Structural simulations enable quicker and more cost-effective insights than physical testing, addressing bore distortion, bending stiffness, load distributions, and fatigue safety factors through realistic elements like non-linearity and Multiphysics.

The main goals of improving chassis and suspension strength, durability, and vibration are to ensure structural integrity, enhance ride quality, and comply with regulations. Reducing unsprung mass while maintaining stiffness improves steering and handling.
