Title:
STRESS ESTIMATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/075768
Kind Code:
A1
Abstract:
The present disclosure provides a stress estimation device capable of estimating, with a higher level of accuracy, the stress acting on a dump truck. A stress estimation device 100 comprises a storage unit 110 and a computation unit 120, and estimates the stress acting on a dump truck 200. The storage unit 110 stores a force computation formula 111 and a stress computation formula 112. The computation unit 120 has a force computation unit 121 and a stress computation unit 122. The force computation unit 121 calculates a force acting on a predetermined part of the dump truck 200 by using: an output value of a force sensor 230, or an output value of an acceleration sensor 240 and the output value of the force sensor 230; and the force computation formula 111 stored in the storage unit 110. The stress computation unit 122 uses a force calculated by the force computation unit 121 and the stress computation formula 112 stored in the storage unit 110 to calculate the stress acting on the dump truck 200.
