Abstract: Reducing vibrations in truck cargo transport compartments has become increasingly important to prevent damage to the cargo and ensure the safety of passengers. Optimising truck cargo transport compartments based on transportation vibration standards such as MIL-STD-810H can considerably improve their performance, reduce transportation damages, and increase the agility and speed of heavy vehicles. The purpose of the current research is to analyse and optimise the cargo transport compartment of the Benz 911 truck by numerical method. For this purpose, the frequency transfer function of the truck cargo transport compartment is determined by considering the effects of the weight of loads and road and engine dynamic forces at natural frequencies. Finally, after 14 optimisation steps, the obtained weight reduction is 38.8% compared to the initial state, and the maximum acceleration has also been reduced by 56.6% compared to its initial value.

Keywords: truck cargo transport compartment; MIL-STD-810H; optimisation; vibration; modal analysis; frequency transfer function.
