| BIFMA X5.9-2004 19 Swivel Cycle Test for Television/Video Display Terminal Surfaces | |||||
| Working Rationale | Motor drive the testing platform. | ||||
| Air cylinder out-force to the testing sample | |||||
| Touch screen input / output, | |||||
| PLC Control. | |||||
| Structure characteristics | 1. Motor drive the testing platform, the frequency transformer control the motor rotation speed and speed conversion | ||||
| 2. Precision manual pressure regulating valve ensure to get the stable and reliable output force and indicate from the digital display. | |||||
| 3. The output end of the cylinder attached the gimbal, adapt to different angles of the chair surface. | |||||
| 4. Simple clamping structure, self-aligning，chair legs without vertical stress, simulate the actual state. | |||||
| 5. Air cylinder out-force in height is adjustable , adapt to different height of chair. | |||||
| Parameter | 1. Digital rotation frequency RPM：5～15CPM. | ||||
| 2. Angle of rotation：Repeated swing or rotate in a single direction. | |||||
| 3. Out-force：158.5KgF | |||||
| 4. Special mechanical design ensure the center of gravity of the load is 2 to 2.5 in forward of the centerline of the rotational axis. | |||||
| 5. Count range：0～999999，Stop / off memory function. | |||||
| 6. Bearing surface height (seat)：350～800mm | |||||
| 7. Turntable diameter：740mm | |||||
| Test objects | All kind of chair with rotating seat | ||||
| Control System | Touch screen with PLC, Stop / off memory function. | ||||
| Breakpoint protection (alarm) function; Gear motor+ Frequency conversion control | |||||
| Manual adjust air pressure. SMC Precision pressure gauge | |||||
| Stop / off memory function | |||||
| Any rotation or 360°rotation mode selection | |||||
