Abstract

The invention provides a roof side rail of a vehicle. The roof side rail of the vehicle comprises a roof rack connecting segment, transition segments and a side wall connection segment, the roof siderail is internally provided with a first supporting beam and a second supporting beam, and the first supporting beam is arranged on the transition segments; the second supporting beam is arranged on the roof rack connecting segment and / or the side wall connection segment; and the thickness of the first supporting beam is greater than the thickness of the second supporting beam. According to the roof side rail of the vehicle, the thickness of the first supporting beam is arranged to be greater than the thickness of the second supporting beam according to the principle that force borne by the first supporting beam between the transition segments is large and force borne by the second supporting beam of the side wall connection segment and / or the roof rack connecting segment is usually small,configuration of oblique reinforcements in the roof side rail of the vehicle is optimized, under the premise of effectively controlling the weight, the overall rigidity of the roof side rail of the vehicle is significantly improved, the rigidity of a high stress zone of a vehicle body is improved accordingly, and thus the problems that in the prior art, a roof side rail of the vehicle is excessively large in overall weight and inconvenient to machine are solved.

Description

technical field [0001] The invention relates to the technical field of vehicle structures, in particular to an upper side beam of a vehicle. Background technique [0002] With the development of our country's social economy and the acceleration of the pace of life, rail transit has become the most important means of transportation in urban traffic. At present, the operating speed of domestic EMUs has reached 380 kilometers per hour. Design requirements for strength, stiffness and lightweight structures. [0003] In order to meet the above-mentioned design requirements in the existing vehicle roof side beam structure, the roof side beam of the vehicle is usually thickened and thickened to improve the installation structure strength of the doors and windows and the overall rigidity and strength of the vehicle. However, with the thickening and thickening of the upper side beam structure of the vehicle, the technological process of processing the upper side beam structure of th...
