Solution Overview

Problem

Current methods for simulating the impact of vehicle wheels on various road surfaces fail to accurately replicate real-world conditions, lacking a comprehensive testing method for non-accident scenarios, which limits the evaluation of wheel performance under realistic traffic conditions.

Innovation Solution

A system comprising a vehicle with a collision vehicle assembly, a tested real vehicle wheel and suspension system, a road surface, high-frequency lighting, a high-speed camera, and a traction motor and steel cable, simulates real impact tests by recreating the interaction of wheels with obstacles, allowing for the measurement of wheel deformation and impact forces.

Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent creates a simplified collision vehicle assembly that copies the essential impact characteristics of real vehicles. The assembly includes a trolley body with weight and fixation device, rear wheel and axle assembly, and tested wheel assembly, which together replicate the fundamental mechanics of vehicle-wheel-road interactions without requiring full-scale vehicles, thereby achieving accurate measurement results while maintaining testing efficiency

Solution Approach 2:

The patent introduces an intermediary collision vehicle assembly that mediates between the simplicity of bench tests and the realism of full vehicle tests. This assembly serves as a middle ground, providing realistic impact simulation through its suspension system, wheel assembly, and controlled collision mechanism, while avoiding the complexity and cost of actual vehicle testing

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If real vehicle wall collision test is used to evaluate vehicle performance in traffic accidents, then the quality of vehicles under traffic accident conditions is improved, but there is no testing method or device for wheels and other vehicle parts under non-accident conditions

Engineering Contradiction:

Solution Approach 1:

The patent designs a universal collision vehicle assembly that can test multiple types of wheels (different sizes, types, and configurations) using the same basic platform. The assembly includes adjustable components such as the tested wheel assembly and suspension system that can be configured for various testing scenarios, making it applicable to both accident and non-accident conditions while maintaining reliable quality evaluation

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent segments the testing system into independent modular components: collision vehicle assembly, tested wheel assembly, suspension system, and obstacle block. This segmentation allows each component to be independently configured and adjusted for different testing requirements, enabling the system to handle both accident simulation and routine quality testing scenarios

Inventive Principle:
Principle #1Segmentation

AI summary

The invention provides a method for simulating real impact test of vehicle wheels, and the method is implemented using a system as follows: the system includes a vehicle used in wheel simulating real impact test, a road surface, a high-frequency lighting facility, a standard obstacle block, a high-speed camera, and a traction motor and steel cable. The method for simulating real impact test of vehicle wheels of the invention has the advantages that: the need for testing various types of wheels using one set of equipment can be satisfied by using a general type collision trolley, thereby avoiding the use of a corresponding real vehicle for each type of wheels in the test. This greatly reduces the test cost, ensures that the test condition is similar to the real vehicle condition, and can well simulate the performance of a real vehicle when meeting an obstacle.
