At first, the root mean square of vibrations<br />at different speeds, as well as in payloads and distribution qualities of materials in the truck dump body<br />and also on different haul road qualities are experimentally obtained. Then, the vibrational health risk<br />in all operational conditions is statistically analyzed based on ISO 2631-1 standard. As a result of this<br />analysis, an optimization problem is constructed and solved to obtain the optimum operating conditions<br />of the truck. In the proposed problem, at first, regression analysis in terms of RMS of vibrations<br />and truck speed is applied. Then, the total RMS at the consequential working phases of the truck is<br />minimized in the presence of some constraints related to the health risk and productivity levels. Solving<br />the proposed constrained optimization problem determines the optimum payload and truck speed in<br />various conditions to keep materials hauling at the lowest possible vibrational health risk level while the<br />mine productivity at the planned level remains. https://ajme.aut.ac.ir/article_2757_d58e2f077670f4de9cd7963c857f2534.pdf
