Push rod failure analysis of a mining heavy dump truck

Push rod failures at early stage are one of the critical issues for the mining heavy dump trucks. The finite element analysis (FEA) model of the dump truck chassis frame was presented. The static, modal and response spectrum analysis for the FEA model was conducted with ANSYS. The results of FEA analysis closely coincided with the actual push rod failure. Based-on this study, the recommended re-design were given.

► Based on the FEA we successfully resolved the critical issues of the push rod failures.
► The finite element analysis (FEA) model of the dump truck chassis frame was presented.
► The static, modal and response spectrum analysis was conducted with ANSYS.
► Feedbacks from the manufacturer verify the effectiveness of recommended modifications.
