Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional drive train test stand is used, then the structure is simple, but the rigidity is insufficient and vibration damping is poor, making it unsuitable for testing electric motor vehicle drives with rotational speeds over 20,000 rpm
Solution Approach 1:
The test stand is divided into modular components including a motor module with yoke-supported electric motor, test part receptacle module, intermediate bearing module, and transmission module. These segments can be independently configured and assembled to achieve the required rigidity for high-speed electric motor testing while maintaining structural complexity at manageable levels through standardized connections.
Solution Approach 2:
The motor module employs a composite construction with a yoke element and housing that form a rigid support structure for the electric motor. This composite design enhances the overall rigidity of the motor module, enabling it to withstand the vibrational forces generated during high-speed operation of electric motor vehicle drives.
2Adaptability or versatility
If a conventional drive train test stand is used, then the installation is simple, but the adaptability is poor, making it difficult to test different drive train configurations without large installation effort
Solution Approach 1:
The test stand is divided into modular components including a motor module with yoke-supported electric motor, test part receptacle module, intermediate bearing module, and transmission module. These segments can be independently configured and assembled to achieve the required rigidity for high-speed electric motor testing while maintaining structural complexity at manageable levels through standardized connections.
Solution Approach 2:
The modular design with standardized connection elements enables the test stand to accommodate various drive train configurations. The same basic modules can be arranged in different configurations to test different electric motor vehicle drives, providing universal applicability across multiple testing scenarios without requiring complete redesign.
3Strength
If the electric motor housing is designed with a yoke for support, then the rigidity and vibration damping are improved, but the manufacturing complexity increases
Solution Approach 1:
The yoke element and housing are merged into a single integrated component that forms a unified support structure for the electric motor. This merging of functions into a single piece reduces the number of separate parts, simplifies assembly, and maintains the enhanced rigidity and vibration damping properties while reducing overall manufacturing complexity.
