Special Issue Information

Dear Colleagues,

The aim of this Special Issue is to present a spectrum of emerging technologies applicable for the design, modeling and, hence, optimization of heavy vehicles and their components.

In the future, vehicles will turn into “smart moveable containers” capable of safely transporting people and goods. Construction of these vehicles requires new design approaches ensuring vehicle stability. Moreover, vehicles will experience a major impact in order to minimize their environmental footprint. Finally, it will become possible to integrate the vehicles in the overall traffic system using ITS techniques.

Therefore, this Special Issue focuses on the promotion and application of new concepts, approaches and pioneering techniques that lead to optimal heavy vehicle performance in terms of mobility, safety, handling, ride quality, stability, reliability, efficiency, as well as economy and impact on environment.

Topics of interest for publication include but are not limited to:

  • Dynamics of heavy vehicle systems and their components (i.e., suspension, steering, braking, chassis systems, noise–vibration–harshness, power train);
  • Computer-aided modeling and simulation, validation, parameter identification and testing in heavy vehicles;
  • Heavy vehicle interactions with the environment including tire–ground behavior;
  • Intelligent heavy vehicles.

We therefore invite papers on innovative technical developments, reviews, case studies, as well as papers from different disciplines relevant to the optimal design of heavy vehicles, their components and superstructures.

Electric retrofitting (e-retrofitting) is a viable option for accelerating the renewal of heavy-duty vehicle fleets to reduce the related emissions. We introduce a simulation-based assessment of e-retrofitting strategies for heavy-duty vehicles. Our simulation tool, an electric vehicle fleet simulation toolbox, comprises three modules, namely driving cycles, vehicle dynamics, and vehicle profiles. The first allows for the creation of realistic driving cycles based on GPS data from real routes. The vehicle dynamics and vehicle profiles incorporate, e.g., the modelling of the powertrain and driving conditions. Ten realistic driving cycles were created and used for investigating and comparing three different powertrain alternatives, including the original diesel powertrain, electric with a single-speed transmission and electric with a multi-speed transmission. The vehicles were simulated in two different heavy-load scenarios. First, driving with a cargo load represented by the maximum vehicle weight and second, driving with snow ploughing. We found that the multi-speed transmission in an electric heavy-duty truck significantly improved its traction performance and gradeability. On the other hand, the effect on the electric powertrain efficiency, and thereby on the energy consumption, remained rather minor. Considering the given workload scenarios, our results advocate employing rather than omitting the gearbox in the e-retrofit truck process. Full article

The design and construction of tanks used for the carriage of dangerous liquid materials fall within strict standards (i.e., EN13094:2015, R111). According to these standards, their supporting structures (Ss), used for the mounting of the tank on the freight vehicle, need to be able to sustain the developed stresses. Optimizing the number of supporting structures can lead to more efficient tank designs that allow the tank to transport more liquid material and need less time to be manufactured. In the present paper, the effect of the reduction of the number of supporting structures in (a) the structural integrity of the tank construction, (b) its dynamic behavior and (c) the load-sharing of the tank to the axles of the freight vehicle is investigated using the finite element (FE) method. As a case study a box-shaped tank mounted on a four-axle freight vehicle with a technical permissible maximum laden mass of 35 tn, five Ss are used. Four FE models with a decreasing number of Ss were built in ANSYS® 2020R1 CAE Software and their structural integrity was investigated. For each design, a feasible design was developed and evaluated in terms of structural integrity, dynamic behavior and axle load distribution. The results of the FE analysis were reviewed in terms of maximum equivalent Von Mises stress and stress developed on the welding areas. Additionally, the axle-load sharing was qualitatively assessed for all feasible designs. The main outcome of this work is that, overall, the use of two Ss leads to a more efficient design in terms of the manufacturing and the mounting of the tank construction on the vehicle and on a more efficient freight vehicle. More specifically, the reduction of the number of Ss from five to two lead to reduction of the tank tare weight by 9.6% with lower eigenfrequencies. Full article
