Comparison of Hand-Arm Vibration on Truck Steering Wheels Based on Speed Changes Using I-Kaz Method

Abstract:

Exposure to high levels of hand-arm vibration (HAV) from the steering wheels can present risks to health and safety to drivers. This study aim to do HAV comparison analysis on the Malaysian Army (MA) three-tonne truck steering wheels in three different speeds, when the truck is stationary with the engine switched on and when truck is moving at speed of 40 km/h and 80 km/h. HAV from the steering wheel were measured by using single axis piezoelectric accelerometer and was connected to Brüel & Kjær Vibration Analyser Type 3649, which is which is capable to produce tangential direction acceleration time discrete continuous raw data in units of meters per second squared (m/s²). The raw data were analyzed using statistical analysis I-kaz method to determine the HAV in relation to difference speed of the truck. Based on the results, HAV experienced by the drivers can be presented in frequency weighted HAV_hwz, I-kaz coefficient (Z^∞) and I-kaz display which the value will increase proportional to the truck speed.
