“…Van type bodies are an integral unit and are made by vehicle producers (complete vehicles). Structurally similar to each other, open and box bodies are usually the vehicle's additional element that requires assembly and approval [2][3][4]. In such a case, the vehicle, before body assembly, obtains the "chassis-cab" type approval with code BX.…”

Issues related to designing support frames and bodies for electric delivery vehicles (eVans) are the topic discussed by engineers around the world. Design processes are based on classic solution models which use structural steel profiles. Directions for development include the production of highly tensile steel frames with increased strength parameters. The authors of the article designed and constructed a prototype polymer body for a delivery vehicle. They conducted detailed multi-variant numerical analyses on the prototype and preliminary experimental tests. The obtained results clearly confirmed the correctness of the formulated thesis about the possibility of designing bodies made of structural plastics dedicated to electric vehicles. For a static-loaded parts of structure uniform stress distribution without concentration, with maximum stress value of 25 MPa was achived. For parts of structure carrying dynamic loads shape-derived stress concentration is inevitable. Nevertheless, the stress level of 96 MPa is within the limits of strength, due to the velocity-dependent material properties.

The structural design of vehicles plays an important role in improving vehicle safety and driving performance. In this study, the frame structure of a van-type electric truck was taken as a research object. Stress, strain, and modal analyses of this frame structure were performed using Abaqus, a finite element software, to verify the rationality and safety of the structural design. The frame structure was optimized by numerical analysis. The fourth beam was moved 524 mm forward between the installation points of the power battery pack and the rear lifting lug of the front leaf spring. Results showed that the optimized frame bending, the full-load braking condition, and the full-load torsional operating condition stresses decreased by 44.499%, 23.364%, and 31.303%, respectively. The bending stiffness of an optimized frame increased by 4.026%, whereas the front and rear torsional stiffnesses increased by 4.442% and 4.092%, respectively.

“…Nowadays, van bodies are based on frame structures produced of aluminum alloy profiles (Szabo, 2018). Searching for new possibilities in the adaptation of vehicle body construction solutions in newly designed eVans (Lubczyński and Zuska, 1998) led to focusing on currently unused materials -polymer composites (Beer et al, 2014).…”

Van bodies are based on frame structures produced of aluminum alloy profiles. Searching for new directions in the development of vehicle bodies for newly designed eVans led to becoming focused on currently unused polymer composites in this area. The authors of the article designed a composite body for a delivery vehicle. They conducted detailed, numerical comparative analyses of the commercial body and the developed solution. The obtained results clearly confirmed the correctness of the formulated thesis about the possibility of designing bodies dedicated to electric vehicles made of structural composites.
