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 an automobile sunroof wind load simulation test platform, which comprises an equipment base, and a horizontal sunroof frame fixing platform is fixed above the equipment base through several support columns; the four corners of the upper surface of the sunroof frame fixing platform are Four quick-release clamps are fixedly installed respectively; manual or electric mechanism can drive the sliding sunroof to slide back and forth on the sunroof frame of the car under test; the structure of the present invention is simple, and the traditional weight-type load is replaced by pneumatic means The method solves the situation that the weight cannot simulate the wind load of any intensity; furthermore, the upward pulling force of the load rope is controlled through the advancing position of the load piston, and then the lifting force of the sliding sunroof is controlled upward by the load suction cup, so as to imitate the actual The pressure difference between the inside and outside of the car when the car is running at different speeds, and then simulate the stress of the sunroof when the real car is running at high speed.
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....
