Tracked Vehicle Hazard Prediction for Track Overheating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tracked vehicles face challenges in measuring and managing high track temperatures, which can lead to damage, especially under heavy loads and high speeds, due to the difficulty in directly measuring the temperature of the moving track.
Innovation Solution
A system that includes a load sensor, speed sensor, and temperature sensor communicating with a control system to determine a hazard parameter based on load, speed, and ambient temperature, allowing for comparison to a threshold and triggering actions to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If direct temperature measurement of the track is attempted, then temperature data can be obtained, but the measurement becomes difficult due to the track being in motion
Solution Approach 1:
The patent uses an intermediary approach by measuring ambient temperature near the track and combining it with load and speed data to calculate track temperature, rather than attempting direct measurement of the moving track. This mediator (ambient temperature sensor) provides indirect but sufficient information to assess thermal hazard.
Solution Approach 2:
The patent replaces direct physical contact measurement (mechanical/thermal contact) with a computational approach using sensors that measure ambient conditions and vehicle parameters. The control system computes track temperature based on the relationship between ambient temperature, load, and speed, substituting direct measurement with indirect sensing and calculation.
2Productivity
If the vehicle operates under heavy load and high speed, then productivity increases, but track temperature rises causing potential damage
Solution Approach 1:
The patent implements feedback by continuously monitoring ambient temperature, load, and speed, then computing track temperature and comparing it to a threshold. When the computed temperature exceeds the threshold, the system provides feedback to the operator through an alert, enabling corrective action to prevent track damage while allowing high productivity operation within safe parameters.
Solution Approach 2:
The patent performs preliminary assessment of thermal hazard by computing track temperature based on current operating conditions before actual damage occurs. By evaluating the combination of ambient temperature, load, and speed in advance, the system predicts potential overheating and alerts operators to adjust operations before critical temperatures are reached.
3Measurement precision
If multiple sensors and computational parameters are used to determine hazard parameter, then temperature monitoring accuracy improves, but system complexity increases
Solution Approach 1:
The patent applies multi-functionality by using a single control system to perform multiple functions: collecting data from multiple sensors, computing track temperature, comparing to threshold, and generating alerts. This universal controller consolidates what could be separate complex subsystems into one integrated unit, reducing overall system complexity while maintaining measurement precision.
Data Source
AI summary
An exemplary method generally involves determining a hazard parameter for a tracked vehicle including a ground interface assembly. The ground interface assembly generally includes a track and a drive wheel operable to move the track to thereby propel the tracked vehicle. A load sensor senses a load carried by the tracked vehicle, and a speed sensor senses a vehicle speed of the tracked vehicle. A control system in communication with the load sensor, the speed sensor, and a temperature sensor determines the hazard parameter based upon the load, the vehicle speed, and an ambient temperature in a vicinity of the tracked vehicle. The control system compares the hazard parameter to a threshold parameter, and performs an action based upon the comparison.
