| Side impact car body and structural analysis
Force in the destruction of the body,mbt shoes sale, the body is not easy deformability. Also refers to the ability to restore the elastic deformation of the prototype. Car in motion the process affected by various external forces cause deformation, the small degree of rigidity is a good, general body stiffness. Strength are better. Stiffness of poor car, driving on uneven road surfaces are likely to issue a \Largely determine the stiffness of the column the overall stiffness of the body, so the entire body structure, the column is the key piece. When the side of the car upon impact. Door in the side under the action of the force of impact, resulting in inward movement of the trend that the inhibition by the car door. Meanwhile,tory burch shoes, the car door by door pass to the lateral force. If the door is installed in the crash beam, the front door by the side kick will be mainly delivered to the hinge pillar and B pillar; the back door by most of the lateral impact force delivered to the B pillar and C pillar. Hinged column under the action of the lateral force is also the trend of movement to the car. Resistance to this trend, mainly in the hinge-side column under the beam by the windscreens and dashboards to provide axial stiffness of the beam installation; column in the bottom of the hinge at the bottom of the main body by the Department to provide lateral stiffness of the structure. C columns subjected to lateral force, the situation is similar. By the side door after impact, the trend of movement to the vehicle under the B pillar bending moment to the role of the car. The deformation of the B pillar of resistance to the car, mainly from the bending rigidity and B pillar, under the joint stiffness. Through the B pillar connector,mbt shoes sale, the role of the B pillar part of the force through the roof edge beams, roof beams and the associated non-impact side of the joint structure to pass. B on the B pillar to pillar joint the resistance movement inside the vehicle is provided by the roof structure, mainly the axial stiffness of the roof beams, roof edge beam bending stiffness, A pillar and C pillar of the bending stiffness, as well as In the above case, the corresponding stiffness of the joint structure; through the B pillar connector, the role of some of the B pillar is passed to the threshold beam power. The role of the lateral force at the threshold of the beam, on the one hand the direct impact from the outside, on the other hand the role from the B pillar. When the B pillar by the bending action at a distance, through joint under column B, the threshold beam inside the body by the thrust, moment and torque around the threshold of the role of beam centerline. In order to increase the overall stiffness of the body and body components of the subsidiary departments and functions, modern vehicles are usually in a variety of components within the board to increase and strengthen beams, inside (outside) tailgate, etc., shown in Figure 2. Accessories, vehicle matching; should meet the requirements of human relations, such as spatial location, operating location and view documents and other requirements to minimize barriers. 3. With the car door with the post box and stiffness (1) post boxes and car door with. Close relationship with the car door post, post the strength and stiffness to be able to withstand the various forces came door system, and has the ability to resist vehicle side crash. Cars and car door hinge post box, limit switch, door lock latches and other installation accuracy and bit 2. The door is the main body side structure of vehicle body side structure from the analysis. Vehicle body side of the door and door and door frame structure with the structure and stiffness of vehicle body side structure of the body. General vehicle door system should have the following functions: opening the door should have the necessary degree,mbt shoes on sale, and turned to stop the greatest degree of opening and half-open position; door safe lock when closed, traffic or a crash, the door not automatically open, the occurrence of side impact or roll the vehicle, the door structure can play a supporting role, and can normally open; operational well, window light, flexible, component system is reliable, durable; has a good seal, so the crew and from the outside world, the minimum transmission car interior noise, dust, and the least amount of exhaust gas inhalation; have sufficient rigidity, not easily deformed sinking, driving sound sluggish; manufacturing process better. Stamping and easy to install and easy styling accessories with the vehicle door coordination gap under the door uniform color and built, directly affect the performance and sealing requirements. Doors and car door frames with control measures is also related to some performance cars, such as anti-flutter, anti-noise and security. (2) car post frame stiffness. In the collision. Composed of thin-walled beam-shaped crew compartment structure of the role are often subject to bending moment, such as the B-pillar side impact and side impact door beams against lateral impact force was caused by the bending moment. So it reduces the stiffness of the crew compartment deformation also play an important role. To further enhance the stiffness of the body side structure, the design of modern vehicles are usually in the following ways: to improve the overall structure of the body side of the rational design of deer just bending moment of inertia of each section, so that affected large parts of the bending moment of inertia is also large; prevent stress concentration, such as unavoidable, appropriate measures should be taken to reinforce the body structure of column B that often occur with the design.
