安全气囊过滤器技术

Helping You Meet USCAR

ACS pyrotechnic airbag inflator filters offer the following advantages over the competition:

Reduced Inflator Open Flame

VEM technology prevents burning pyrotechnic particles from escaping the filter.

Reduced Inflator Tank Wash

ACS is able to reduce the tank wash over a normal wire mesh filter by up to 50% using VEM technologies. This results in cleaner and safer airbag  inflator.

Reduced Airbag Cushion Damage

Excess cushion and pin hole burns are typically the result of burning particles that escape a filter: a problem typical in traditional laminar flow filter
technology but solved with ACS’s VEM technology.

Adjustable for Specific Combustion and Performance Gates

ACS engineers can quickly adjust the filter’s internal combustion pressure and the tank ballistic performance gates with minor filter changes to
meet a customer’s acceptance gates, most often without major generate nor propellant load changes.

VEM Filters

ACS’s patented Variable Expanded Metal (VEM) filters are constructed from a single sheet of expanded metal and combined with woven mesh when needed. Multiple layers of expanded metal are stacked, each with different hole counts and hole sizes, creating a more turbulent flow through the filter and preventing bag burns.

Inflators that fill the bag with pyrotechnics produce a burning jet fire. The jet fire is filled with copper and other molten metals that must be cooled and plated without exiting the inflator. If the filter has the same hole profile in all layers, then negative laminar gas flow is obtained, especially when the layers nest, creating direct flow paths for the burning jet fire particles to exit the inflator.

ACS filters use flow profiles that reduce the open flame by capturing all larger burning particles before they can exit the filter and the inflator; in all radial gas flowing and most axial gas flowing inflators. The result is cooler exit gas temperatures, and a cleaner, safer gas filling the airbag cushion.

Adjustable for Specific Inflator Combustion & Tank Performance Gates

ACS believes that filters for airbags are not heat sinks nor are they coolants, which function using convection heat transfer. A fast Mach gas velocity deployment time of less than 40ms invalidates the heat sink concept, making normal convection heat transfer formulas non-relevant. ACS believes the filter’s cooling is thus not based upon convection cooling; inflator performance is solely based upon the principles of thermodynamic cooling.

Rather than a coolant or a heat sink, ACS thinks of airbag inflator filters as thermodynamic diffusers. With this classification in mind, an engineer can quickly adjust both the filter’s internal combustion pressures and the tank’s ballistic performance gates with minor modifications. In this way we can meet a customer’s acceptance gates, most often without major generate nor propellant load changes. When designing a filter as a thermodynamic diffuser instead of a heat sink, the filter can become a much better generate slag trap, which helps to reduce overall inflator cost.

New Technology

Not only can we reduce the weight of a filter by as much as 50% below that of traditional wire mesh filters, making the inflator more sustainable by removing excess weight, but we can also allow inflator designers to engineer smaller, lighter, inflators with identical or improved cushion fill output volumes. These new technologies include, VCEM (Variable Crimped Expanded Metal), DFEM (Directional Flow Expanded Metal) and Ultra-lite VEM (or Variable Expanded Metal that removes 30-50% of the mass vs. traditional straight expanded metal filters).

Prototyping

ACS has a world class prototype filter department and software modeling technology to quickly help you design and alter the filter to meet your customers’ requirements and save development costs and reduce inflator cost as new inflator development takes time and costs are high. Please ask us about anything airbag filter related and we can help.
