“…Pure bending stiffness is analyzed by applying 1,500 N of the force at the center of the left and right sides (Figure 4a), representing a bending load placed upon the L7e structure. The constraints are defined at both the front and rear wheels to take the bending deformation of the body frame (Fang and Kefei, 2019). Figure 4b illustrates the loading condition to analyze the safety under bending and combined bending stiffness.…”

“…Structural deformation from the pure torsion case occurs when couple forces of 2,000 N are applied to the left and right front wheels (Figure 5a) while the rear wheels are constrained in all translational directions (Fang and Kefei, 2019). In the case of combined torsion load representing the occasion that the left front wheel falls into a pothole, the force twice the total body weight is applied to the left front wheel, whereas the other wheels are constrained (Chen et al, 2015) (Figure 5b).…”

The lightweight design of electric heavy quadricycle (L7e) vehicles has contributed to energy savings and sustainable mobility. This study proposes an optimization methodology to design a monocoque sandwich structure under operating conditions for an L7e using a finite element model via HyperWorks. Woven fiberglass fabrics and high-density PVC foam are assigned as the face and core to construct the sandwich structure, respectively. Free-size optimization based on weight minimization is applied to obtain the suitable initial thickness of face and core structures in all components. Multi-objective size optimization is then performed by minimizing both mass and material cost to determine the optimal thickness of each layer. Finally, shuffle optimization is used to modify the stacking sequence for each component to maximize structural stiffness. The results indicate that the core thickness in the passenger compartment is sufficient to maintain stiffness while maintaining the structure's lightweight. However, shuffle optimization is insignificant for the current monocoque model, as the structural stiffness is only marginally improved after the process. Additionally, this study examines the optimized models for structural stiffness and discusses suitable procedures for designing a lightweight and safe electric vehicle.

With the development of the times, our life is becoming more and more intelligent. In this regard, we have also made great progress in the field of communication intelligence. But we still need optical wavelength devices to generate ultra-continuous spectromets that can be used in the field of communications. In this regard, the purpose of this paper is to study the optical wave guide device to generate ultra-continuous spectrum algorithm, and its simulation and analysis. The experiment in this paper begins after careful consideration of the security of user data and some trade secrets, and on the premise of experimental security, the accuracy of the algorithm is measured and simulated by using sandbox simulation based on computer technology. The experimental results show that the algorithm can increase the speed of ultra-continuous spectrum of optical wave guide device by about 50%. And in the simulation simulation application, the stability is good.

The mototaxi, a three-wheeled vehicle equipped with a roof, is a widely utilized mode of transportation in Mexico. Typically, it is employed for short-distance journeys in exchange for payment, similar to the operation of a conventional taxi. This study conducts astructural analysis of a mototaxi-type vehicle utilized in Mexico to assess its performance and safety. It underscores the significance of this mode of transportation, widely relied upon by numerous individuals. A product design and development methodology was employed, utilizing torsional deformation simulations to validate the new geometry. The objective was to minimize torsions as much as possible, thereby enhancing the motorcycle taxi’s safety and ensuring the vehicle’s correct positioning. Through computeraided design, the prevailing torsions within the casing were assessed, establishing the operating conditions to which the system is commonlysubjected. The findings from the chosen vehicular structure reveal a flexural rigidity of 6,508.15 N/mm, torsional rigidity of 27.35 KNm/°, and a range of natural frequencies between 8-21 Hz. These values indicate favorable resistance against bending forces and operational frequency. However, the torsional results exhibit deficiencies, suggesting an unsafe structure for all motorcycle taxi occupants. Consequently, technology developers and national legislators should prioritize enhancing the structural integrity of such vehicles.
