CAE (Computer Aided Engineering) is a technology that combines computer technology with engineering analysis techniques to solve complex engineering problems, analyze structural mechanics performance, and optimize structural performance. It has been developed for over 50 years, starting from its early application in engineering in the 1960s. In the 1990s, CAE software products emerged, offering a wide range of element types, material models, and discipline-specific analysis models.
CAE software, essentially scientific computing, is utilized in industrial fields and serves as the foundation for concepts like “intelligent manufacturing,” “industrial Internet,” and “digital twins.” It plays an indispensable role in the research, development, and design processes of new energy vehicles.
The role of CAE technology in the design process of new energy vehicles can be summarized as follows:
1. Enhancing design capabilities by ensuring the rationality of product design and reducing design costs through computational analysis.
2. Shortening design and analysis cycles.
3. Acting as a “virtual prototype” through CAE analysis, greatly reducing the resource-intensive process of physical prototype validation in traditional design. Virtual prototypes can predict product reliability throughout their lifecycle.
4. Employing optimization design to identify the best product design solution and reduce material consumption or costs.
5. Preemptively identifying potential issues before product manufacturing or engineering construction.
6. Simulating various testing scenarios to reduce testing time and expenses.
7. Conducting mechanical accident analysis to investigate accident causes.
CAE analysis cases
An example of CAE analysis is the strength analysis of the vehicle frame. The frame plays a crucial role in the overall structure of a car, bearing various loads that directly impact the vehicle’s lifespan and safety. Through CAE software, a comprehensive strength analysis of the frame can be performed under multiple operating conditions, ensuring that the frame and related components meet the requirements and guaranteeing the safety of the vehicle.
The battery pack, a core component of new energy vehicles, accounts for a significant proportion of the entire vehicle. Multi-operational strength analysis and modal analysis of the battery tray ensure its reliability and stability.
CAE technology has been widely applied in the quality and performance analysis processes of automobile design. It effectively reduces repetitive processes, shortens the development cycle, improves comfort and safety, and promotes the advancement of the automotive industry.
