Problems solved by technology
[0002] When the car is running at high speed, the sunroof will be subjected to the pressure difference between the upper and lower sides, which will cause the sunroof to form an upward wind load. In order to ensure that the sunroof can be opened, slid and closed smoothly during the high-speed driving process, it is necessary to carry out the wind load simulation of the car sunroof. At present The sunroof load test often adopts the method of valve counterweight, because the number of weights cannot be divided infinitely, this method can only simulate the wind load of a specific intensity

The invention discloses a wind load simulation testing platform of an automobile skylight. The testing platform comprises a device pedestal. A horizontal skylight frame fixation platform is fixedly arranged above the device pedestal through a plurality of support columns. Four quick-dismounting clamps are fixedly installed at four corners of the upper surface of the skylight frame fixation platform. A manual or electric mechanism can drive a sliding type skylight to slide back and forth on a tested automobile skylight frame. The testing platform has a simple structure. The pneumatic mode is used for replacing the conventional weight type loading mode, so that a phenomenon that the weight can not realize simulation of the wind load with random intensity is avoided; the upward dragging forceof a load rope is controlled by the boosting position of the load piston and thus a load sucking disc is controlled to increase the lifting force of the sliding type skylight upwardly, so that the vehicle inside-outside pressure difference caused by driving of the real vehicle at different speeds is simulated and thus the skylight stress condition of the real vehicle in high-speed driving is simulated.
Description
technical field [0001] The invention belongs to the field of automobile sunroof testing. Background technique [0002] When the car is running at high speed, the sunroof will be subjected to the pressure difference between the upper and lower sides, which will cause the sunroof to form an upward wind load. In order to ensure that the sunroof can be opened, slid and closed smoothly during the high-speed driving process, it is necessary to carry out the wind load simulation of the car sunroof. At present The sunroof load test in China often adopts the method of valve counterweight. Since the number of weights cannot be divided infinitely, this method can only simulate the wind load of a specific intensity. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a wind load simulation test platform for an automobile sunroof capable of simulating any wind load and a test method thereof....
