Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing vehicle test rigs are used, then basic wheel testing can be performed, but they fail to effectively simulate dual-axle vehicle corner systems under various road conditions including longitudinal forces, lateral forces, and vertical loads
Solution Approach 1:
The test rig is divided into separate functional modules: a support frame for structural stability, wheel support surfaces for positioning, actuators for applying forces, and rotatable members for simulating wheel motion. This segmentation allows each component to be optimized for its specific function while working together to simulate complex road conditions.
Solution Approach 2:
The test rig incorporates dynamic capabilities through actuators that can repeatedly move wheel support surfaces in directions perpendicular to the surfaces, and rotatable members that can rotate to support spinning wheels. These dynamic elements enable the system to simulate varying road conditions including longitudinal forces, lateral forces, and vertical loads that change over time.
2Reliability
If a comprehensive test rig with multiple actuators and rotatable members is implemented, then accurate simulation of road conditions is achieved, but device complexity increases
Solution Approach 1:
The test rig employs universal components that perform multiple functions. For example, the actuators not only move wheel support surfaces but also apply controlled forces to simulate various road conditions. The rotatable members simultaneously support spinning wheels and enable steering motion. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The wheel support surfaces act as intermediary elements between the actuators and the wheels. These surfaces transmit forces from the actuators to the wheels while providing a stable mounting interface. This intermediary structure simplifies the connection between force-application mechanisms and wheel assemblies, reducing overall system complexity.
3Measurement precision
If the test rig includes computing device for real-time calibration and feedback, then compliance with vehicle specifications is ensured, but use of energy and system complexity increase
Solution Approach 1:
The computing device receives signals from sensors in real-time and processes this data to determine whether subsystems meet predefined specifications. Based on this feedback, the system automatically calibrates sensors and adjusts test parameters. This closed-loop feedback mechanism ensures measurement precision while automating the calibration process to reduce manual intervention.
Solution Approach 2:
The computing device performs self-calibration by processing sensor signals and automatically adjusting system parameters based on predefined specifications. This self-service capability eliminates the need for continuous manual calibration, reducing energy consumption associated with human operation while maintaining high measurement precision.
