奥迪汽车专修车内的安全性能的要求

来源:http://www.jnrunao.com/ 日期:2020-10-13 发布人:runao
在现代汽车上,车身内部一切有可能与人体撞击的构件都应避免采用尖角、凸棱或小圆弧过渡的形状,而且车身室内广泛采用软材料包垫。室内软化不仅是为了满足舒适性要求,更重要的还是为安全防护性能的要求。
In modern automobile, the shape of sharp angle, convex edge or small arc transition should be avoided for all components inside the body which may impact human body, and soft materials are widely used in the body interior. Indoor softening is not only to meet the requirements of comfort, but also to meet the requirements of safety protection performance.
奥迪汽车专修根据碰撞安全性的要求,车身壳体的正确结构应是,使乘客舱具有较大的刚度以便在碰撞时尽量减小变形,同时使车身的头部、尾部等其它离乘员较远的部分的刚度相对较小,在碰撞时得以产生较大的变形而吸引撞击能量,显然,如果车身乘客舱按照汽车行驶时的载荷来设计,其刚度就显得不足,还需要进行局部加强。乘客舱较易加固的是地钣、前围内钣、后围钣等宽大的部件。
According to the requirements of collision safety, the correct structure of the body shell should be to make the passenger compartment have greater stiffness, so as to reduce the deformation as much as possible during the collision. At the same time, the stiffness of other parts of the body far away from the passengers such as the head and tail of the body are relatively small, which can produce large deformation and attract the impact energy during the collision. Obviously, if the passenger compartment of the car body is in accordance with the When the load is designed when the vehicle is running, its stiffness appears insufficient and needs to be strengthened locally. It is easy to reinforce the wide parts of the passenger compartment, such as the floor plate, the front inner panel and the rear panel.
门、窗孔洞的周边则是薄弱环节,但风窗支柱和中立柱的断面尺寸又不宜过大,所以只能在其内部贴上较厚的加强钣。在汽车碰撞时,为避免整个乘客舱的构架产生剪切变形或坍塌,更重要的是加固门、窗周边的拐角部分,可在其上贴上加强钣或加大拐角处的过渡圆角。
The periphery of the door and window hole is the weak link, but the section size of the wind window pillar and the middle column should not be too large, so only thick reinforcing plate can be pasted inside. In order to avoid shear deformation or collapse of the whole cabin frame during vehicle collision, the most important thing is to reinforce the corner parts around the door and window, which can be pasted with reinforcing plate or the transition fillet at the corner can be enlarged.

要使乘客舱获得必要的刚度,不能仅靠局部补强的办法,而应就整个车身结构通盘考虑。众所周知,杆件或梁在弯曲时变形较大而在拉伸或压缩时变形较小。
In order to obtain the necessary stiffness of the passenger compartment, we should not only rely on local reinforcement, but also consider the whole body structure. It is well known that the deformation of a member or beam is large in bending and small in tension or compression.
为了使车身头部和尾部的刚度较小,可以在粗大的构件或强固的部件上开孔或开槽来削弱其刚度,或者使构件在汽车碰撞时承受弯曲载荷。车身前部安装发动机和前悬架的纵、横梁都较粗大,因此某些现代轿车的前部纵梁不是平直的,而是有意弯折成Z字形以便在碰撞时折叠变形并吸收冲击能量。
In order to make the stiffness of the body head and tail smaller, holes or slots can be made on the thick components or strong parts to weaken the stiffness, or to make the components bear bending load in the car collision. The longitudinal and transverse beams of the engine and the front suspension in the front of the vehicle body are relatively thick. Therefore, the front longitudinal beams of some modern cars are not straight, but deliberately bent into a Z-shaped shape, so as to fold and absorb the impact energy during collision.
奥迪汽车专修为使乘客舱侧面较强固以便承受较大的撞击力,车身的门槛通常较粗大,并用横梁将左右两根门槛连接起来共同受力。此外在门外钣的内表面还常常贴有瓦楞状加强钣。
In order to make the side of passenger compartment stronger and stronger so as to bear larger impact force, the door sill of Audi car body is usually thicker, and the left and right doorsill are connected by crossbeam to bear the force together. In addition, the inner surface of the door plate is often pasted with corrugated reinforced plate.
