The National Instruments USB-4431 dynamic signal acquisition DSA module acquires data at rates from 1 to 102.4 kS/s, which makes it possible to obtain a wide measurement bandwidth. The combination of the USB-4431 and the new vibration sensors, which include three accelerometers, a triaxial accelerometer and an impact hammer, gives engineers a complete stimulus-response system […]

The Society of Automotive Engineers (SAE) International has produced a simple, consistent and economical sound test standard that can be used to determine whether a streetbike (on-highway motorcycle) exhaust system emits excessive sound, the AMA reports.
The J2825 “Measurement of Exhaust Sound Pressure Levels of Stationary On-Highway Motorcycles,” issued by the SAE in May, establishes instrumentation, […]

The Sound Level Technical Committee handles the development of standards related to noise control. It’s seeking members to participate in the standards development process. The standards include the test procedures for sound level measurement (SAE J88 and SAE J919), noise exposure (SAE J1166) and the effectiveness of audible warning systems (SAE J994, SAE J1105, and […]

LMS International’s NVH Observer is a subscription-based database with vehicle NVH benchmarking information. Currently, the database contains fourteen reference vehicles with plans to increase it by at least 8 vehicles on an annual basis. For each vehicle in the database, NVH Observer includes 6,000 curves such as spectra, orders, sensitivities, TPA noise contributions, modes and […]

The Series 3713 triaxial DC response accelerometers from PCB Piezotronics (PCB®) are designed for a variety of NVH and vehicle durability measurements in automotive and off-highway applications. For example, these accelerometers can be used for brake deceleration compliance certification; vehicle radiator and air cooler durability testing; roll stiffness/static rollover threshold tests; NVH testing; and […]

Concurrent’s SIGnal Workbench is a dynamic data acquisition and monitoring system for rotational machinery, structural, and other vibration applications. The product provides everything needed for high-cycle fatigue testing: a real-time computer system, data acquisition input cards, programmable signal conditioning and powerful graphical test software for data acquisition control, data management, display and post-test analysis.
SIGnal […]

PCB Piezotronics’ new series of pedal effort load cells are aimed at automotive test applications, including brake development, drivability, vehicle handling, and legislative & safety testing. Designed to measure the force required to operate a vehicle’s primary brake, clutch, or floor-mounted emergency brake pedals, the Series 1515 brake pedal effort sensor with integral cable is […]

Acheson recently announced that it has upgraded its acoustic laboratory to support the global weather strip seal coating market. The upgrade consists of adding Ziegler friction test systems to the MB dynamics instrumentation it already had to measure acoustic quality. Acheson also redesigned its acoustic laboratory to bring the ambient noise level below 30 decibels […]

The Oros Mobi-Pack is a 16-channel, all-in-one vibration analyzer designed for tough field environments. Its rugged and light weight design lets it be checked with luggage or even carried on board an aircraft. Shocks and vibrations during transport or even operation will not prevent it from acquiring the critical data it is meant to capture.
Features […]
