How to calculate the capacity of tpu inflatable airbag

tpu inflatable airbag is a lightweight, high-strength gas-enclosed structure made of thermoplastic polyurethane (TPU) material, which is mainly used in automotive, military, medical and other fields. In order to ensure the use effect and safety of TPU inflatable airbag, it is necessary to calculate the capacity of the airbag accurately.

To calculate the capacity of the TPU inflatable airbag, consider the following factors:

Inflation pressure: The pressure of an inflatable airbag is the pressure of the gas inside the airbag, usually expressed in pascals (Pa). Different air bags may have different inflation pressures, so you need to determine the specific inflation pressure in order to calculate the capacity of the air bag.

Bag shape and size: The shape and size of the bag also have an important effect on the calculation of the bag capacity. air bags are usually divided into round, rectangular, oval and other shapes, and the size of the different uses vary. When calculating capacity, you need to make calculations based on actual shape and size.

Air bag operating environment: Air bag operating environment is also one of the factors affecting capacity calculation. For example, factors such as temperature, humidity and vibration that the air bag is subjected to during operation will affect its capacity, so these factors should be fully taken into account.

Generally speaking, the formula for calculating the capacity of the TPU inflatable airbag is:

Capacity = inflation pressure x airbag shape factor x airbag area

Among them, the airbag shape factor is an empirical value, which can be adjusted according to the actual situation. For airbags of different shapes and sizes, corresponding shape coefficients should be used.

When calculating the capacity of TPU inflatable airbag, it is necessary to select appropriate calculation methods and formulas to ensure accurate and reliable calculation results. At the same time, it is also necessary to fully test and verify the capacity of the air bag to ensure that it meets the actual use requirements.
