Simulated transport shaking table


Overview:

Simulated transport shaking table, also known as "shaking table", to simulate the car during the transport of bumps caused by the destruction of the product to identify whether the product endure the ability of environmental vibration, suitable for electronics, electromechanical, photoelectric, steam locomotives, toys ... Industry research, development, quality control, manufacturing

 

Product Standards:

This Simulated transport shaking table complies with EN71 ANSI, UL, ASTM, ISTA and other test standards.

 

standard test:

The ISTA test standard is the American Transport Association standard, ASTM is the American Materials Association standard, two standards for the simulation of transport vibration equipment requirements are: amplitude of 25.4mm (1 inch, fixed), frequency 1.5-5Hz (or 100-300 turn / Minute adjustable), the test is based on: T = 14200 / CPM (based on the total number of vibration is 14200 times), test speed selection.

Simulate the purpose of transporting shaking tables:

The purpose of the simulated shaking table is to make a series of controllable vibration simulations in the experiment to test whether the product can withstand the test of environmental factors such as transportation or vibration during the life cycle and to determine the requirements for product design and function. According to the statistics show that the level of 3% increase in design, will increase the 20% recovery and reduce the 18% of the unnecessary expenses. Vibration simulation according to different purposes also have different methods such as resonance recording, resonance resident, cyclic scanning, random vibration and stress screening, and vibration effects include:

1.  the strength of the structure.

2.  the release of the conjugate.

3. protective materials are worn.

4. the damage of components.

5. the electronic components of the poor contact.

6. the circuit short circuit and intermittent instability.

7. the standard deviation of each piece.

8. simulated transport shaking table early defective screening.
