Abstract
The invention provides a force loading method used for a vehicle chassis test. One of two opposite action points of a first linear driver is connected onto a force-applying point of a chassis to be detected, and the other action point is connected onto a fixing component. Force bore on the force-applying point is increased by controlling extension of the first linear driver. According to the method, the first linear driver is adopted to act as a force-applying part to be connected with the chassis of the tested vehicle. Size of a load (i.e. action force) loaded on the chassis can be conveniently controlled via controlling extension of the first linear driver so that operation is relatively simple. Besides, compared with the mode of loading heavy counterweights for acting load in the prior art, the heavy counterweights are saved and space for placing the heavy counterweights is not needed correspondingly by adopting the aforementioned method so that test place is saved and place utilization rate is enhanced.
