Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a stress calculation system of a dump truck capable of highly accurately calculating time variation of stress occurring at a predetermined position (evaluation position).SOLUTION: The stress calculation system of a dump truck includes: a storage device 32 for storing data of stress occurring at a vehicle evaluation position of the dump truck when multiple external force is applied on the dump truck respectively; an acceleration sensor 110 for detecting a direction and magnitude of the external force applied on the dump truck; and a calculation processing unit 31 for estimating time variation of the stress occurring at the vehicle evaluation position, by interpolation or extrapolation based on a detected value of the acceleration sensor and the stress data stored in the storage device.
