Vibration Sensor Risk Assessment for Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for assessing transportation risk, such as those based on ASTM and ISTA standards, are inadequate for accurately predicting vibration-induced fatigue damage during actual transportation conditions, as they rely on specified loading capacities and suspension systems, which often do not reflect real-world scenarios.
Innovation Solution
A system and method involving a sensor on the vehicle's floor to collect vibration signals, with a computing device performing time-domain and frequency-domain processing to output actual vibration intensity and duration, and a risk assessment procedure comparing these data to reference values to determine a risk level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If ASTM or ISTA standards are used for vibration assessment, then a standardized testing procedure is established, but the assessment accuracy for actual transportation conditions deteriorates
Solution Approach 1:
The patent changes the assessment parameters from fixed standard values to actual measured values. Sensors collect real vibration data during transportation, and the system processes these actual parameters (acceleration, frequency, duration) to assess risk, replacing the standardized hypothetical parameters with real-world measurements for accurate assessment
Solution Approach 2:
The patent replaces the mechanical standardized testing system with an electronic sensing and processing system. Instead of using physical vibration tables and standardized procedures, the system uses sensors, signal processors, and computer algorithms to collect and analyze actual vibration data, achieving more accurate and flexible assessment
2Reliability
If specified loading capacity and suspension system are assumed, then a baseline vibration model is created, but the adaptability to actual cargo conditions deteriorates
Solution Approach 1:
The patent transforms the static baseline model into a dynamic adaptive system. The vibration assessment is no longer fixed but dynamically adjusts based on actual measured conditions. The system continuously collects real-time vibration data and adapts the risk assessment to match actual cargo characteristics, transportation routes, and vehicle conditions
Solution Approach 2:
The system performs self-adjustment by automatically collecting actual vibration data and using it to refine the risk assessment. Instead of requiring external calibration for different cargo types, the system self-adapts by measuring real conditions and processing the data through the established model, making the assessment automatically suitable for various cargo conditions
3Loss of information
If vibration signals are collected based on specific transportation route, then route-specific data is obtained, but the representativeness for overall vibration level deteriorates
Solution Approach 1:
The patent implements continuous vibration signal collection throughout the entire transportation process. Sensors continuously monitor vibration parameters from departure to arrival, ensuring no useful vibration information is lost. This continuous data collection provides a complete picture of the vibration environment, making the assessment representative of the overall transportation conditions
