背景技术Background technique
现在有很多汽车的前轮罩存在着悬置动刚度不足的问题，而大部分车企通过加一根横梁直接连接前纵梁和上纵梁，来解决此处悬置动刚度不足的问题。例如，起亚智跑类型的汽车就是在通过一根横梁直接连接前纵梁和上纵梁来提升前轮罩的悬置动刚度，以增强车身刚性，改善NVH(Noise、Vibration、Harshness，噪声、振动与声振粗糙)性能。起亚智跑这种加横梁的解决方案，存在过设计问题，会导致汽车重量增加，成本上升，不利于精细化设计。Nowadays, the front wheel housings of many cars have the problem of insufficient suspension dynamic stiffness, and most car companies solve the problem of insufficient suspension dynamic stiffness by adding a beam directly connecting the front longitudinal beam and the upper longitudinal beam. For example, the Kia Smart Run car directly connects the front longitudinal beam and the upper longitudinal beam through a beam to increase the suspension dynamic stiffness of the front wheel cover, so as to enhance the body rigidity and improve NVH (Noise, Vibration, Harshness, noise, vibration and harshness) performance. The solution of adding beams to the Kia Smart Run has design problems, which will increase the weight and cost of the car, which is not conducive to refined design.
