Problems solved by technology

[0006] So far, the domestic automobile industry's evaluation method for the durability test of the fuel tank bracket assembly is mainly to monitor during the vehicle road test and proving ground test, which is time-consuming and laborious, and the repeatability is poor, which affects the product development process; the indoor bench test is only It is possible to test the static strength or static stiffness of the fuel tank bracket assembly, and there is no test bench for testing the durability of the fuel tank bracket assembly
The system disclosed in Patent Document 1 can only realize th

Embodiment Construction

[0040] The fuel tank bracket assembly multi-axial loading test stand of the present invention will be described in detail below in conjunction with the accompanying drawings. There is a brief introduction to the drawings that need to be used in the technical description. Obviously, the drawings in the following description are some embodiments of the present invention. For those of ordinary skill in the art, without paying creative labor Below, other drawings can also be obtained from these drawings.

[0041] see figure 2 , the present invention provides a fuel tank bracket assembly multi-axial loading test bench, said test bench is composed of a longitudinal loading device, two lateral loading devices, three vertical loading devices and a connecting frame.

[0042] Such as figure 2 As shown, preferably, the longitudinal loading device includes: a longitudinal actuator support 1; a longitudinal actuator 1 1 ; Longitudinal change to the tripod 1 2 ;Longitudinal loading gu...

Abstract

The invention discloses a fuel tank bracket assembly multi-axis loading test stand and an endurance test method. The test stand comprises loading devices fixed on an iron floor and a fuel tank bracketassembly connection frame. The connection frame connects the loading devices and a fuel tank bracket assembly into a multi-axis loading system. The loading devices comprise one longitudinal loading device, three vertical loading devices and two side loading devices. Through coordinated movement of the six loading devices, space six-degree-of-freedom motion of the fuel tank bracket assembly is realized. Compared with the prior art, the method, with a test field reinforced road load spectrum signal being a target, and through a simulative iteration mode, can realize true reappearance of space six-degree-of-freedom vibration state and stress state of the fuel tank bracket assembly under a real vehicle working condition in a test room, and further realizes endurance test and test authentication of the fuel tank bracket assembly. In the product development process, test cycle can be reduced greatly, weak spots can be found earlier, and research and development cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of performance testing of automobile products, and in particular relates to a multi-axis loading test bench for a fuel tank bracket assembly and a durability test method. Background technique [0002] With the continuous advancement of science and technology and the continuous improvement of living standards, people have higher and higher requirements for the performance of automobile products, and the high reliability of the complete vehicle and its parts is an important symbol of modern automobiles. [0003] The automobile fuel supply system is the source of automobile power. Among them, the fuel tank bracket assembly supports the quality of the fuel tank. Once it breaks, it will directly cause the fuel tank to fall off, interrupt the power source, and easily cause traffic accidents, especially for poor driving conditions. For engineering vehicles, the impact of the road surface is large, and the working e...
