Project Code: 16039
Project Title: Strut Condition Monitor for Large Mining Trucks
Project Type: Industry
Project Intellectual Property: Company Controlled
Project Citizenship Restriction: No
Sponsor Company: Caterpillar Inc.
Description: Strut failure on the CAT 770 mining truck means costly downtime for the sponsor’s customers. The objective of this project is to design and implement a monitoring system for the truck’s hydraulic struts. The system needs to monitor strut performance continuously during truck operation and alert the driver to strut behavior that indicates it is damaged. Data gathered by the system from pressure, temperature and displacement sensors on the hydraulic struts is processed through developed algorithms to determine if the strut’s behavior matches the ideal within a set tolerance. The driver is prompted with the error and a mitigation strategy, such as recharging the strut with nitrogen or replacing it before it fails.
