The invention belongs to the technical field of bench experiment devices, and particularly relates to an automobile rigidity-adjustable bench experiment device and a rigidity adjusting method thereof. According to the technical scheme, the automobile rigidity-adjustable bench experiment device comprises a bottom plate, wherein the top of the bottom plate is fixedly connected with supporting rods; the ends, away from the bottom plate, of the supporting rods are fixedly connected with an installation fixing plate; the inner wall of the installation fixing plate is in threaded connection with first bolts; the first bolts penetrate through the installation fixing plate; the outer walls of the first bolts are in threaded connection with limiting nuts; the outer walls of the first bolts are in threaded connection with a top plate and a side plate; and the side plate is fixedly connected with an auxiliary plate through second bolts. The automobile rigidity-adjustable bench experiment device and the rigidity adjusting method thereof provided by the invention have the beneficial effects that the rigidity of a supporting column can be adjusted through the number and the positions of the first bolts, the rigidity of the device can be adjusted by adjusting the height of a supporting barrel, and the rigidity can be adjusted by changing included angles between inclined supporting rods and the supporting column, so that the rigidity adjusting modes are multiple, the rigidity adjusting range is large, the precision is higher, and the usability is higher.
Description
technical field [0001] The invention relates to the technical field of bench test devices, in particular to a bench test device with adjustable stiffness of automobiles and a stiffness adjustment method thereof. Background technique [0002] Fatigue test is a theoretical study aimed at the continuous performance degradation or even destruction of a certain product or component caused by repeated work within a limited period of time. At present, the fatigue test of a complete vehicle or a component usually uses a bench test device. Corresponding fixtures are set on the bench test device to clamp the whole vehicle or other parts to be tested, so as to realize the fatigue test on the whole vehicle or other parts. [0003] The existing bench test device has a single rigidity adjustment method and type, and the range of the fatigue test is limited, which results in low accuracy of the fatigue test. [0004] Therefore, it is necessary to invent a bench test device with adjustable...
