1、黑龙江工程学院本科生毕业设计附 录A(外文文献)Body collision correction In modern automobile body for main body structure of space vehicle ,integral of the body in order to absorb energy collision, automotive usually designed as in collision, by making by pieces of broken folded and body to absorb the impact energy; The
2、relay route crash force ,can such image depicted as will the culmination of collision point as the collision, cone-shaped centerline can harness karabiners direction for collision, The depth and scope of conical expansion, said the crash force function direction and the transmission range. through b
3、ody. Integral by stamping thin body structure formation, metal material plate connected to the welding, most of the collision impact energy was bought component metal materials plate pieces, collision and shock absorption, the influence of the component is through the body passed,therefore, the memb
4、er body repair people based on this idea of analysis, design of the collision of the repair process program body. Auto body injury can through comparing the gap between body structure, also can judge by comparing the front wing son plate and the clearance before judge wheels; Also can measure the in
5、stalling hole behind the front bumper frame beams parts prior to the left and right sides of the size of the comparison of the car body, many cars have high installation clearance requirements. Body damage when the examination, should check component of the gap between and cooperate, because each bo
6、dy structure smell with hinge is installed in the car door pillar, publication in order to determine whether the damage, such as door pillar by closing and opening the doors can be simple method, to observe the position is correct. In a front-end collision accident, important is to inspect the back
7、door and wing of the differences between son board, another option is more car controls two side clearance. In order to hold the space body possible examine all damage, can be divided into five ministries and space body inspect. First part: direct collision point directly damage caused, carefully ex
8、amined the bodywork pieces of metal coating, plastic, glass of body accessories, decoration and body components such as outer panel damage; For example in the front of the collision of the case, the site should check at least include: front bumper system, grille, engine cover, the former guard board
9、, halogen halogen lamps, glass, the doors and the wheels;If the collision point in a cars rear, should check at least include: the parts HouYi son after bumper system, after the board, luggage, lights, glass, wheels, etc.; If the collision point in a cars profile, should check parts include at least
10、 the original: the door, roof, glass, pillar, floor plate part and suspension, etc. The second part: refers to the outside except the collision point occurred in other parts of the damage; Therefore, it may involve large scope.Check indirect damage, should check clear collision force size, direction
11、, absorb impact strength, etc; component.Observe component surface trace, any body thin metal materials purchase components can be generated by the collision extrusion, tiny flaw .For example body roof damage, should present the convex shape body component individual Angle inspect component of metal
12、 material yield conditions The third part: mainly is the inspection car parts, check the damage engine and sports system undamage each assembly. The fourth part fourth place: basically check passenger cabin, uncover the damage part accessories carpet and insulation materials, observe around the surf
13、ace of the metal material components, check seats installation, seat belt anchor, instrument panel, etc. The damage marks,can also rotating direction in run straight disc wheel steering dish, saw his position in the middle, and whether without free trav.The fifth part: check whether the bodywork com
14、ponent, decorative thread matching aligned and coating whether state, etc. Do not think that the work is not important, is a waste of time, the body of the collision of the correction, collision damage examination is the key body calibration process. Auto repair correction body, there is one basic p
15、rinciple, namely in accordance with collision force opposite directions in collision regional correction and exert tension corrected. Automobile body damage when collision damage is small, according to the injury, this method is simple to have the effect very much, now all vehicle body repair worksh
16、op are already equipped with body panels.it repair machine, so simple and easy to repair operations. The causes of automobile body damage is very complicated, because body structure and component forming reasons, especially by body structure of thin-walled box component, the analysis of the impact and repair, such enormous difficulties with simply cant tensile operating mode is body returning to its original shape. For example, under the car after collision
