Technical Field
[0001] The utility model belongs to the technical field of seat bump test, and particularly relates to a frequency sweep tooling for seat bump test. Background Technique
[0002] The frequency sweep tooling for seat bump test is a test device used to detect and evaluate the performance and comfort of automotive seats on bumpy roads, and is composed of a frequency sweep vibration table, a seat fixing device, sensors and a data acquisition system, a control system and analysis software.
[0003] In the existing seat bump test, the seat is usually fixed on the frequency sweep vibration table by using bolts. The frequency sweep vibration table usually has multiple threaded holes for installing the seat. However, since the sizes and shapes of the seats are different, the positions of the mounting holes on the mounting plate at the bottom of the seat are also different. And the positions of the threaded holes on the frequency sweep vibration table are fixed. Therefore, when fixing the seat, some seats cannot align the mounting holes with the threaded holes better, which affects the fixing of the seat, and other auxiliary fixing tools need to be used in cooperation. Therefore, we propose a frequency sweep tooling for seat bump test. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a frequency sweep tooling for seat bump test. By setting a moving component, specifically, the moving seat can drive the mounting seat to adjust the front and rear positions, and pushing the mounting seat can adjust the left and right positions. By adjusting the front, rear, left and right positions of the mounting seat, the threaded holes can be better aligned with the mounting holes on the seat, which is convenient for the staff to fix the seat, and can install seats of various different shapes and sizes, and is more widely used. It solves the problem that the positions of the threaded holes on the frequency sweep vibration table in the existing seat bump test are fixed. Since the sizes and shapes of the seats are different, the positions of the mounting holes on the mounting plate at the bottom of the seat are also different. Therefore, when fixing the seat, some seats cannot align the mounting holes with the threaded holes better, which affects the fixing of the seat.
