ISO 2631 5 Evaluation of Multiple Shock Vibration Test
The ISO 2631-5 standard provides a framework for evaluating multiple shock and vibration tests, offering methods to assess the comfort and ergonomic impact on human operators in vehicles. This evaluation is crucial for ensuring that automotive NVH (Noise, Vibration & Harshness) performance meets regulatory requirements and customer expectations.
The standard focuses on the evaluation of the human body's response to vibrations and shocks during vehicle operation. It helps to ensure that vehicles provide a comfortable environment for the driver and passengers by minimizing uncomfortable or harmful vibrations. This service is particularly important in the automotive sector, where comfort and safety are paramount.
ISO 2631-5 defines specific testing protocols and criteria for measuring the human body's response to vibration and shock. The standard covers various aspects of vehicle design that can affect NVH performance, including seat design, suspension systems, and engine mounts. By adhering to this standard, automotive manufacturers can ensure that their vehicles meet international safety and comfort standards.
The evaluation process involves subjecting the test specimen (the human body) to a series of shock and vibration tests under controlled conditions. The test parameters are carefully selected to simulate real-world driving scenarios, ensuring that the results accurately reflect the vehicle's NVH performance in everyday use.
Once the testing is complete, detailed reports are generated, providing insights into the vehicle's NVH characteristics. These reports can help manufacturers identify areas for improvement and make informed decisions about design changes or component modifications. The information provided by these tests is invaluable for R&D engineers and compliance officers, as it helps ensure that vehicles meet both regulatory requirements and customer expectations.
For a more comprehensive understanding of the ISO 2631-5 standard, we can provide a detailed table outlining the scope and methodology. This table will help you understand how this standard applies to automotive NVH testing.
Applied Standards
- ISO 2631-5: Human exposure to whole-body vibration – Part 5: Evaluation methods for multiple shock and vibration environments
- ASTM E904: Standard Practice for Determining Vibration Dose Values (VDVs)
Scope and Methodology
| Aspect | Description |
|---|---|
| Data Collection | Involves measuring the vibration and shock experienced by the human body during vehicle operation. This is done using accelerometers placed on key areas of the seat and floor. |
| Subject Selection | The subjects for testing are carefully selected to represent a wide range of body types and sizes, ensuring that the results are applicable to all potential vehicle users. |
| Data Analysis | The collected data is analyzed using specific algorithms provided in ISO 2631-5. These algorithms calculate the VDV (Vibration Dose Value) for each test subject, which reflects their exposure to vibration and shock. |
