The invention, which belongs to the technical field of automobile product performance testing, discloses a multi-axial loading test stand and endurance test method of a commercial vehicle storage battery support assembly. The multi-axial loading test stand comprises a loading device, a simulated frame, and a connection clamp fixedly connected with the simulated frame. With the simulated frame and the connection clamp, the loading device and a storage battery support assembly are connected to form a multi-axial loading system. The loading device consists of three first loading units and three second loading units; and on the basis of coordinated movement of the six loading units, spatial six-freedom-degree movement of the storage battery support assembly is realized. According to the endurance test method of a storage battery support assembly, with a reinforced road load spectral signal of a test field as an objective, the spatial six-freedom-degree vibration state and stress state of the storage battery support assembly on the actual vehicle working condition can be represented in a laboratory practically; and thus endurance examination and test authentication of the oil tank holder assembly can be realized.
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 battery bracket assembly of a commercial vehicle and a durability test method. Background technique [0002] The battery is one of the very important parts of the car. It is connected in parallel with the generator on the car and supplies power to the electrical equipment. The battery should be firmly fixed on the longitudinal beam of the car to prevent the battery The bracket is loose, justified, etc. [0003] The battery bracket assembly carries the mass of the battery, and once it breaks, it will directly cause the battery to fall off, especially for engineering vehicles with poor road conditions, the road impact is large, and the working environment of the battery bracket assembly is even worse. In the process of product development, it is necessary to carry out durability performance assess...
