Side Collision Test Apparatus for Integrated Vehicle Body Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current side collision testing methods for vehicle bodies are costly and lack accuracy due to the need for repeated real vehicle tests, which are performed on individual parts rather than the integrated side structure assembly unit.
Innovation Solution
An apparatus connecting a side carriage to a side structure assembly unit, featuring 'L'-shaped brackets, 'V'-shaped members, gap step members, and pillar connection members, which form spaces and angles to simulate deformation and rotation, allowing for a more integrated and accurate assessment of side collision impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If repeated real vehicle tests are performed for empirical analysis, then test accuracy is improved, but test cost increases excessively
Solution Approach 1:
The patent creates a simplified test model that copies the essential structural characteristics of the actual vehicle side structure. This model includes simplified representations of the side sill, pillar, and roof rail connections, allowing repeated testing without the need to test the actual vehicle multiple times, thus reducing test cost while maintaining accuracy.
Solution Approach 2:
The test apparatus divides the complex vehicle side structure into separable components (side sill part, pillar part, roof rail part) that can be independently assembled and tested. This segmentation allows the test model to be reused and reconfigured for different testing scenarios, reducing the need for repeated real vehicle tests.
2Device complexity
If tests are performed on individual parts rather than integrated assembly, then test complexity is reduced, but integrated assessment accuracy deteriorates
Solution Approach 1:
The patent merges multiple individual part tests into an integrated assembly test. The test model combines the side sill part, pillar part, and roof rail part into a unified structure that can be tested as a complete assembly, allowing assessment of the integrated side structure while maintaining manageable test complexity through standardized connection methods.
Solution Approach 2:
The test apparatus is designed with universal connection structures (such as standardized brackets and mounting mechanisms) that can accommodate different vehicle models and configurations. This multi-functionality allows the same integrated test setup to assess various side structure configurations without requiring complete redesign, thus maintaining integrated assessment accuracy while controlling complexity.

AI summary
An apparatus for testing a side collision with a vehicle body connects between a side carriage for testing a side collision and a side structure which includes a roof rail part configured to be connected to an upper portion of the side carriage, a side sill part configured to be connected to a side lower part of the side carriage, and a pillar part configured to connect between the roof rail part and the side sill part and be connected to a pillar of the side carriage. The side carriage is connected to the side structure while forming a space between the side carriage and the side structure.
