大众新速腾后悬架纵臂断裂的原因(国外英文资料) The cause of the collapse of the suspension arm of the Volkswagen after the new speed The 2015-10-15 15:43? Is there any reading for the rights of the BMW car? 1294 (autumn wind, senior engineer) ? (2) analysis and description of the cause of the rupture of the new rapture ? See the above picture, it is not hard to see, all arm fracture source are in the same place, the trailing arm on the narrow part of the section, and the fracture shape basic are all the same, what reason is this? ?? Heres a scientific analysis of the structure and shape of the forearm. ????? (1) the first step of the basic condition of the new rapid-beam arm is measured, and the thickness of the new rapid-length longitudinal beam is 3.00 mm; The upper part of the arm is curved, and the length of the forearm is wider, narrower, and narrower, while the lower part is basically a straight line. The arm of the audi 100 is a more robust casting, while the thickness of the nylon arm is 5mm and the thickness of the new rapid-length beam is 3mm. To save materials, the public USES only 3.00 mm to make the long arm of the new speed. In order to solve the strength of the 3.00 mm sheets trailing arm, mass forging in the trailing arm up and down, the section pressure of various curvy shape, in principle is to enhance the strength of the 3.00 mm sheets trailing arm; But the problem is that if you have a straight line up and down, the bending degree of the cross section of the forgings is essentially the same. The shape of the arm of the new speed, the lower part is basically a straight line, and the upper part is an arc of nearly twice the width of the head. In this case, the same shape is not possible in the upper and lower segments. See below, The section of the new raping column is different from the lower part of the previous section, and the section of the lower part is semi-circular, with a smooth, smooth, smooth and small opening. And in cross section, bending uneven and not smo
