Abstract

ABC operates within the engineering and construction sector, specializing in the service and provision of advanced heavy equipment, including the DV17 type Dump Truck. This Dump Truck model features a loading and unloading body capable of supporting loads of up to several tons. However, there are noted deficiencies in the effectiveness and efficiency of the Sidewall stiffener section, which utilizes 6 supports. A modification was carried out by creating 3 variants or forms of stiffeners. The design method used is the Pahl & Beitz concept design method, with testing performed through static and dynamic simulations using Finite Element Analysis (FEA). Simulation results show that Variant 2 performed the best in both static and dynamic tests, with static simulation values showing stress at 88 MPa, strain at 0.1, displacement at 0.8 mm, a safety factor of 2.9, and a weight of 818.16 kg. The dynamic simulation for Variant 2 recorded stress at 187 MPa, strain at 0.1, displacement at 1.7 mm, and a safety factor of 1.3. When compared to the existing design by PT. ABC, Variant 2 demonstrates superior performance. The current PT. ABC design presents static simulation values of 301 MPa for stress, strain of 0.1, displacement of 4.7 mm, and a safety factor of 0.8. Dynamic simulations reveal a stress value of 411 MPa, strain of 0.1, displacement of 5.1 mm, a safety factor of 0.6, and a weight of 802.63 kg. This indicates that Variant 2 provides optimal performance and a balanced trade-off between safety and stability.
