Description

Objective:

The vibration frequency analysis of the chassis-battery system is used to determine the natural frequencies and vibration modes of the chassis-battery system. This can help engineers design:

• Safety Evaluation: Ensure the system can withstand dynamic loads and vibrations without failure, protecting the battery and other components.
• Quality Improvement: Reduce noise and vibration, providing a smoother and more comfortable driving experience.
• Weight Optimization: Identify unnecessary parts that can be removed without affecting performance or safety, helping to reduce the vehicle’s weight.

Requirements:

• Modeling: Create a detailed 3D model of the chassis-battery system, including materials, shapes, and connections.
• Software: Use specialized analysis software such as ABAQUS, NASTRAN, ANSA.
• Input Data: Provide information about dynamic loads and boundary conditions for the model.

Results:

Modal analysis provides the following information:

• Natural Frequencies: The frequencies at which the chassis-battery system tends to resonate the most.
• Vibration Modes: The manner in which the chassis-battery system moves at each natural frequency.
• Stress and Deformation: The levels of stress and deformation the chassis-battery system experiences at each natural frequency.

Applications:

The results of modal analysis can be used to:

• Improve Design: Modify the shape or material of the chassis or battery to avoid dangerous natural frequencies.
• Design Suspension Systems: Develop suspension systems that help reduce vibration and noise.
• Identify Damage Locations: Detect damage in the chassis-battery system by comparing analysis results with actual measurement data.
