EN71 Transportation Simulator System For Improvement Of Product
Quality
Product Overview
Simulation transport vibration table, also known as "vibration
table", simulate the damage caused by the turbulence of the product
during automobile transportation, to identify whether the product
is able to withstand environmental vibration, suitable for
electronic, mechanical and electrical, optoelectronics, motor
vehicles, toys and other industries of research, development,
quality control, manufacturing.
The simulation transportation vibration test bench is suitable for
vibration test of toys, electronics, furniture, gifts, ceramics,
communications, equipment, computers and auto parts, etc., to
inspect its transportation effect or durability uniformity.
This machine according to the European and American similar
equipment restructuring, rotary vibration, in line with the
European and American transportation standards, in line with EN71
ANSI, UL, ASTM, ISTA and other test standards.
Test purpose
This machine is a series of controlled vibration simulation in the
experiment to test whether the product can withstand the test of
transport or vibration environmental factors in the life cycle, and
can also determine the requirements of product design and function
standards. According to statistics, improving the design level by
3% will increase recycling by 20% and reduce unnecessary expenses
by 18%.
1. Strength of structure.
2. Loosening of the bond.
3. Protect the wear and tear of materials.
4. Damage of components.
5. Poor contact of electronic components.
6. Circuit short circuit and intermittent instability.
7. Deviation of the standard value of each piece.
8. The simulated transport shaking table will screen out the
defective parts in advance.
9. Find the resonance relationship between parts, structure,
packaging and transportation process, and improve its resonance
factors.
The requirements of the simulated transportation vibration test
bench are to confirm the reliability of the product and to screen
out the defective products before leaving the factory in advance,
and to evaluate the failure analysis of the defective products in
order to become a high level and high trust product.
Instrument Characteristics
1. Use digital instrument to display vibration speed, which can be
adjusted according to demand;
2. Synchronous silent belt drive with low noise;
3. The sample clamp adopts guide rail type, easy to operate and
safe;
4. The base of the machine adopts heavy channel steel with
vibration damping rubber pad, easy installation and smooth
operation (if the test speed needs high-speed operation for a long
time, it is recommended to install anchor screws);
5. AC variable frequency motor speed regulation, smooth operation,
strong load capacity.
Introduction to vibration testing
1. Place the test product on the vibration test platform with
normal transportation. In order to prevent jumping off the table
and maintain the direction, the vibration test platform can be
surrounded by ropes;
2. The vibration frequency should be just enough to shake the goods
off the table, and the metal sheet can be inserted between the
sample and the table, and can walk in the longest edge gap of the
sample (the thickness of the metal sheet is 1.5mm, the width is
50mm (optional));
Test speed CPM | Corresponding frequency Hz | Test time M |
150 | 2.5 | 95 |
180 | 3.0 | 79 |
210 | 3.5 | 66 |
240 | 4.0 | 60 |
270 | 4.5 | 53 |
300 | 5.0 | 48 |
