Using a portable braking-performance instrument: procedure and precautions
Fit the contact switch to the brake pedal, connect its cable and the acceleration sensor to the host, then attach and align the acceleration sensor on the windscreen.
Portable braking-performance instruments: principle and precautions
A portable braking instrument measures deceleration with an acceleration sensor. Its acquisition unit processes and analyses the signal to calculate vehicle braking parameters.
Verification and calibration of vehicle inspection equipment: what is the difference?
Verification and calibration differ in purpose, scope and nature. Verification assesses equipment against metrological requirements and accuracy limits; calibration evaluates measurement accuracy.
Types of vehicle braking-test equipment and how they differ
The main braking inspection instruments are portable braking testers, roller reaction brake benches and plate brake benches. Portable instruments are particularly suitable for rapid batch inspections.
Steering force and angle instrument: operation and general technical requirements
Secure the steering force and angle instrument to the vehicle’s steering wheel and tighten the bolts. After powering on, clear the previous test data before starting real-time measurements.
Vehicle testing equipment: lateral stability test system launched
After 12 months of development, Naiou launched the VEM-1178 lateral stability test system for JT/T 1178.1 and JT/T 1178.2. It supports indoor and vehicle tests with real-time results.
Complete-vehicle performance inspection: tests and measuring equipment
Complete-vehicle inspection covers power performance, fuel economy, braking, speedometer accuracy, headlamps, emissions and noise. Road tests use dedicated vehicle performance testing systems.
Using a vehicle fuel-consumption testing system: procedure and precautions
Install the fuel meter and sensors according to the manual, switch on the instruments, set the test date, select the test programme and press START to begin.
Vehicle pass-by noise testing methods and test-site requirements
Vehicle performance testing is mainly carried out on outdoor roads, with some tests performed indoors.
