Study on the roll-over protective structures of off-highway dump truck

This article takes a mining dump truck as the research object, designs an integrated ROPS structure and performs loading analysis based on ANSYS software according to ISO 3471-2008. Through the analysis of the deflection of the ROPS structure during the loading process, it is judged whether the ROPS structure can meet the requirements specified in the standard. The results show that no part of the ROPS component invades the DLV interface during the lateral, vertical, and longitudinal loading process. The ROPS structure can effectively protect the driver in the event of a vehicle rollover accident.
