im体育APP’s large multiaxial silent shaker can perform buzz, 吱吱声, and rattle (BSR) testing with fast turnaround times on automotive components up to 700 lbs to help manufacturers create quieter products.
With the increasing demand for electric vehicles, automotive manufacturers will see an ever-increasing need to evaluate their components’ buzz, 吱吱声, and rattle performance due to lack of engine noise. BSR testing allows manufacturers to modify their designs before the component becomes a problem for the consumer or a warranty issue for the manufacturer.
Multi-channel data collection Our Buzz, 吱吱声, and rattle testing capabilities
im体育APP Warren houses one of the largest silent shakers in the mid-west. The 6ft wide by 40in deep table can be used for the BSR testing of automotive components such as consoles, instrument panels, 门, full rows of seats, or quarter car bodies. The 700lb weight limit allows for the vibration of components that would typically be too large or heavy for a silent shaker system.
im体育APP’s shaker features multiaxis vertical pitch and roll testing as well as sequential 4-axis testing to mimic real-world road conditions. Configurations of smaller components can also be run simultaneously, significantly reducing turnaround time.
im体育APP conducts BSR testing in a semi-anechoic chamber with an advanced twelve-channel sound collection system for acoustic data collection. With twelve ½ inch pre-polarized free-field microphones, the test set-up ensures maximum data capture so our experts can quickly localize the source or cause of an unwanted sound.
Our assembly consists of:
- 700lb silent shaker
- 6ft x 40in table with various extensions and multi-axis vertical pitch and roll testing
- Sequential 4-axis testing
- Semi-anechoic chamber
- Twelve 1/2 inch pre-polarized free-field microphones for acoustic data collection
Supportive 测试 Methods with im体育APP
With extensive expertise in the transportation industry, our experts offer additional Noise, Vibration, and Harshness (NVH) testing capabilities outside of BSR testing, including:
- Sound power/intensity
- Natural frequency analysis
- Pass by noise and sound 质量
- Additional single axis for buzz, 吱吱声, and rattle analysis
- Drive-in Hemi Anechoic chamber
“im体育APP's engineers were very careful to obtain the proper means of performing the test to our standards.”
