WIPO Patent Application WO/2022/138058
Kind Code:
A1
Abstract:
This state management device manages a state of a work machine. The work machine is provided with a work device, a posture detection device that detects posture information of the work device, and a motion detection device that detects motion information of an actuator. The state management device is provided with a control device that performs calculation on the basis of detection results of the posture detection device and the motion detection device, and an output device that outputs calculation results of the control device in a recognizable form. The control device calculates accumulative damage degree of a driven member on the basis of the posture information of the work device and the motion information of the actuator, stores time variations of the accumulated damage degree at a predetermined position of the driven member, and outputs information showing the time variations of the accumulated damage degree at the predetermined position.
