Sakor Technologies discuss the importance of NVH testing in engine development

With OEMs continuing to improve NVH, Sakor outlines its newest testing innovation and the importance of accelerated belt aging stands in vehicle development

 

 Sakor Technologies, a leading dynamometer testing instrumentation company, has developed and supplied an accelerated belt aging stand to Ford for use in belt noise testing. The new preliminary conditioning equipment will be used to prepare belts for the full testing required to meet SAE J2432-2012 specifications for belt noise in vehicle Front End Accessory Drive (FEAD) applications.


The company’s new conditioning stand subjects belts to dynamic loads, temperatures and stresses that will give them the physical characteristics of aging belts. Artificially accelerating the aging process introduces the noise characteristics that can then be properly tested to ensure they meet SAE J2432-2012 standard. This new standard covers accessory drive belt testing methods and includes test configurations, pulley diameters, power loads, as well as guidance for interpreting test data.


The auto maker’s original aging stand was designed to condition only one belt at a time, at a fixed load. The new stand can age up to three belts at a time, reducing the time necessary to test a given belt design. Ford will use the stand to test new belt materials, designs and manufacturers to evaluate how they are likely to perform once installed in an engine for a period of time.


“The new aging unit has been very well received by Ford,” said Randal Beattie, president at Sakor. “We are excited to add this enhanced stand to help Ford improve its ability to evaluate belt performance in accordance with the new SAE test standards.”
