The main function of the simulated vehicle vibration testing machine is to simulate the vibration of the vehicle during transportation to detect damage to items during transportation, thus achieving better packaging protection.
The simulated automotive vibration testing machine is suitable for packaging, toys, electronics, ceramics and other products that require packaging protection. The simulated automotive vibration testing machine is a widely used test equipment for logistics and transportation.
Operating principle of vibration:
The vibration table can be divided into:
1. Scientific research machines and Testing, Electromagnetic Vibration Table.
2. Production and Processing Machinery, Electromagnetic Vibration Table
3. Production and Assembly Machinery, Electromagnetic Vibration Table
MechanicalVibration adopts cam eccentric device, adjustable weight eccentric device, etc.;
Electromagnetic vibration adopts electromagnetic coil exciting mechanical vibration device and the like.
The functional principle of the vibrating table: The current-carrying conductor moves under the influence of electromagnetic force in the magnetic field.
When the induction coil in the magnetic circuit of the electromagnetic vibration table passes through the AC signal, an excitation force is generated and a vibrating movement is generated in the magnetic circuit. Similar to a dynamic speaker.
Purpose of the vibration table test:
The random vibration test is suitable for components and devices that may be affected by random vibration conditions in use.
The purpose is to run a series of controllable simulated vibrations in the experiment to test if the product conforms to Transporttest or various vibration environmental factors during the life cycle, and to determine the vibration test bench design criteria and functional requirements.
1. The working principle of ordinary mechanical vibration table:
The mechanical vibration table is mainly composed of a working table, a vibration suspension mechanism, a vibration spring group and other components: When working, a group of eccentric gears are driven by the speed-regulating motor to rotate, and the working table is pushed to increase and decrease the vibration in the vertical direction.
2. The working principle of ordinary electromagnetic vibrating table:
The electromagnetic vibrating table is mainly composed of a workbench, an electromagnetic excitation coil, a moving coil work surface, a level thatmade up of springs and other components. By the electromagnetic excitation control device, the work table is driven to increase and decrease the vibration in the vertical direction.
