Embodiment Construction

[0020] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0021] The specific embodiment of the method for rapid verification of the vehicle skeleton in the present invention, such as Figure 1-3 As shown in Fig. 1, pits and / or bumps are set on the test track to simulate the impact conditions on the real road surface, and the rapid verification of the vehicle skeleton is realized by testing the stress peaks of the impact conditions.

[0022] In this embodiment, a foundation pit is set on the test track, and a support frame 3 is set in the foundation pit. The device also includes a pit module 1 with a concave portion 11 for simulating road pits and / or a pit module 1 with a boss for simulating road surfaces. The raised boss module 2, the top of the support frame 3 has a connection structure for detachable fixing with the pit module 1 and / or the boss module 2, and the support frame 3 includes a structure for accom...

Abstract

The invention relates to a method for quickly verifying a vehicle frame so that problems of high cost and long cycle of verification of a vehicle frame in the prior art can be solved. A pit and/or protrusion that are/is used for simulating an impact work condition on a real road surface are/is arranged on a proving road; and a stress peak of the impact work condition is tested to realize quick verification of the vehicle frame. When a vehicle frame needs to be verified and tested, simulation of the serious impact work condition of the vehicle on the real road surface is realized by the pit orprotrusion, so that the verification result is close the rear situation. Meanwhile, because of the simulation of the serious impact work condition of the vehicle frame, the verification strength of the vehicle frame is improved equivalently, so that the full-life verification cycle is reduced. When the vehicle frame has a local defect, only verification of the serious impact work condition needs to be carried out on the local defect of the vehicle frame by the pit and the protrusion on the proving road to realize the full-life verification effect instead of full-life verification testing, so that the cost is saved and the verification cycle is reduced.

Description

technical field [0001] The invention relates to a method for quickly verifying a vehicle skeleton. Background technique [0002] In the bus structure, the bus frame is both a load-bearing unit and a functional unit. As the main bearing part of the bus, it is composed of the body frame and the underframe. During the driving process of the bus, it must bear the load of various complex road surfaces. The bus frame must have sufficient strength, stiffness and fatigue durability to resist external loads. Therefore, before the bus products go on the market, it is necessary to verify the whole life of the bus frame through testing methods, so as to avoid the problems of the bus frame going to the market, causing inconvenience to users, and even causing traffic accidents, resulting in personnel and property losses. [0003] At present, the evaluation and verification of the bus frame is mainly achieved through the full-life test of the whole vehicle on the test track of the proving...
