The invention discloses a fixing device for a stiffness test on a front end frame of a vehicle. The fixing device includes a chassis, a base, a base connecting assembly and a front frame end connecting assembly. The base is fixed on the chassis and provided with a plurality of mounting holes therein. The base connecting assembly is fixed with the base through the mounting holes. The base connecting assembly is provided with a sliding part thereon. The front end frame connecting assembly is movable along the length direction of the sliding part and can be positioned on an arbitrary position of the sliding part. The front end frame of the vehicle is suitable for connection with the base connecting assembly through the front end frame connecting assembly. With the fixing device according to the embodiment of the invention, different sized front end frames of the vehicle can be fixed on the fixing device without additional design of an experimental sample vehicle, the test cost is reduced, the test time is shortened, and the stiffness test on the front end frame of the vehicle is further facilitated.
Description
technical field [0001] The invention relates to the field of vehicle engineering, in particular to a fixing device for a stiffness test of a vehicle front end frame. Background technique [0002] As the core component of the vehicle, the design and testing technology of the front-end module frame of the vehicle play a key role in controlling the final quality of the product. In the preliminary design process, the stiffness test of the front frame is often carried out on the test sample vehicle. Due to the differences in the size and shape of the vehicle front-end frames of different models, in the prior art, it is necessary to separately design experimental prototypes for the vehicle front-end frames of different models, which greatly increases the test cost, complicates the test process, and prolongs the test time. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefo...
