| Title | An Investigation into the Influence of Commercially Available Fender Brace Configurations and Designs on Front-End Deformation | ||

| Abstract | Safety" is an important part of automobile development and design. Some automobile companies even regard "safety" as the primary brand image of the automobile factory. With the advancement of technology, more and more automobile manufacturers pay attention to the "active safety equipment" of automobiles. For example, Adaptive Cruise Control (ACC), Lane Keeping Assist System (LKAS), Lane Departure Warning (LDW), Autonomous Emergency Braking (AEB) represent active safety protection using technology to improve driving safety. Before an accident occurs, when the vehicle loses control, the system intervenes in the safety equipment so that the driver can restore control of the vehicle and "avoid" the accident. "Passive safety equipment" can protect the safety of the occupants of the car to the greatest extent when an unfortunate incident does occur or the vehicle has lost control, such as bumpers; anti-collision steel beam design; compensatory restraint safety system SRS (airbags) and other equipment. The rigidity of the vehicle body has a key impact on handling performance, driving stability and safety. As vehicle design moves towards lightweight and high performance, engineers need to ensure sufficient structural rigidity while reducing the weight of the vehicle body, which becomes an important design challenge. As a part of vehicle body iv reinforcement, the fender brace has the main function of strengthening the front suspension area, reducing local body deformation, and thus improving steering response and dynamic stability. However, the structure and shape of the fender brace not only affect its reinforcement performance, but also the weight distribution and installation convenience. Therefore, optimizing its design has important research value for improving the overall performance of the vehicle. This experiment explores the reinforcement effect of commercially available fender tie rods. By setting the same restrictive conditions and comparing the longitudinal, lateral, maximum deformation and weight of tie rods of different shapes, the reinforcement effect is evaluated. The results show that although Model 11 is the lightest (122.85kg), the deformation data is the worst; although the sheet tie rod can effectively suppress deformation, it is heavier; the flat tube tie rod is lighter, but the deformation suppression effect is not as good as other types; the round tube tie rod achieves the best balance between deformation control and weight, among which Model 08 performs best, and its maximum deformation is reduced by 16.40% compared with Prototype. Comprehensive evaluation shows that the round tube tie rod is the best reinforcement type, and Model 08 is the best fender tie rod design. |
