Dynamic impact of ageing dump truck suspension systems on
dump truck assembly resulting in whole body vibration (WBV) exposures to operators. The truck suspension system performance deteriorates with time; therefore their effectiveness in attenuating vibrations reduces. No research has been conducted to study the impact of ageing suspension mechanisms on the magnitudes of WBV in HISLO operations.

Artificial intelligence, machine learning and process
To verify the feasibility of applying the ACS-SSI algorithm to fault diagnosis of dump truck suspension, an eleven-DOFs dynamic model of a dump truck was established. Secondly, the road roughness signal simulated using Matlab/Simulink software, was input into the dynamic model to obtain vibrational responses [ 31, 32 ].

Influence of long-waved road roughness on fatigue life of
Asymmetrical long-waved road unevenness can accelerate the fatigue failure of the dump truck frame. Due to the difficulty of the tire damping modelling and the complex pitch motion of balanced suspension, it is hard to reveal the relationship between the parameters of long-waved road and the fatigue life of dump truck frame. Firstly, on the premise of not introducing truncation error, by
