Description

A comprehensive test bench for seat fatigue performance

technical field

The utility model relates to a fatigue comprehensive test bench, in particular to a mechanical device for detecting the fatigue performance of each moving part of a passenger seat of an EMU.

Background technique

   In order to ensure the comfort of the passengers, the passenger seat of the EMU needs to frequently adjust the angle of the backrest and the height of the armrest; in addition, it is also necessary to step on the foot pedal, and the backrest can automatically rotate under the action of the motor to ensure that the passenger faces the vehicle when riding direction of travel. At the same time, during the use of EMU passenger seats, the backrest, armrests and cushions will also bear the impact load imposed by passengers. Therefore, the comprehensive fatigue life of EMU passenger seat is an important quality performance index. At present, there is no special equipment for comprehensively testing the fatigue performance of moving parts such as seat backs, armrests, cushions, and pedals for EMU passengers.

In order to prevent the third adjusting plate from damaging the backrest during the process of pushing the backrest, an elastic element is designed on the third adjusting plate.

The backrest test component is mainly used to detect the fatigue performance of the backrest when the angle is adjusted. The backrest test assembly includes a first cylinder support and a first cylinder installed on the frame, the piston rod of the first cylinder is connected to the first steel wire rope, and the first steel wire rope is connected to the backrest clamp by going around the first guide pulley. When the first cylinder is activated, the piston rod will frequently tighten and loosen the backrest through the first wire rope to detect the fatigue performance of the backrest.

The armrest test component is mainly used to detect the fatigue performance of the armrest when the angle is adjusted. The armrest test assembly includes a second air cylinder support and a second air cylinder installed on the frame, and the piston rod of the second air cylinder is connected to the armrest fixture. When the piston rod of the second cylinder stretches, it will pull the armrest to rotate up and down to detect the fatigue performance of the armrest.

The cushion test component is mainly used to test the fatigue performance of the seat cushion when the cushion is in use. The cushion test assembly includes a third air cylinder support and a third air cylinder installed on the support plate, and the piston rod of the third air cylinder is connected to the cushion fixture. When the third cylinder is activated, the piston rod will push the cushion clamp to squeeze the cushion to detect the fatigue performance of the cushion and backing plate. In addition, the support plate fixes the third cylinder of the cushion test assembly through the bolt group. In order to meet the cushion test requirements of seats of different specifications, two U-shaped grooves are designed on the support plate, so that the third cylinder can be adjusted by loosening the bolt group. The left and right positions of the cylinder support.

The pedal test component is mainly used to detect the fatigue performance of the pedals in use. The pedal test assembly includes a fourth cylinder support and a fourth cylinder installed on the frame, the piston rod of the fourth cylinder is connected to the second steel wire rope, and the second steel wire rope is connected to the pedal clamp by going around the second guide pulley. When the fourth start, the piston rod will frequently tighten and loosen the pedals through the second steel wire rope to detect the fatigue performance of the pedals.

The test bench also includes a control cabinet, which is used to control the motor of the test bench and the start and stop of each cylinder.

The utility model can comprehensively detect the fatigue performance of moving parts such as seat backs, armrests, cushions, and pedals for EMU passengers. The operation is safe and reliable, and it can be compatible with seats of different specifications. Reduced production costs.
