ANALISA KARAKTERISTIK GETARAN TRUK MOLEN KAPASITAS 3-5 METER KUBIK BETON COR BERDASARKAN KECEPATAN 30;45;50 (KM/JAM) UNTUK DAERAH HORIZONTAL, LONGITUDINAL DAN VERTIKAL BERDASARKAN TIME DOMAIN

Abstract

Convenience and safety at a time when driving is a very needed by the users of transport services. Measurement of vibration is one way that can be done to monitor the level of comfort in driving and further by vibration analysis can be known exactly if any interruption occurred during in the course. Therefore, researchers want to find out how the analysis of the vibration characteristics of truck molen capacity 3-5 cubic meters of concrete cast based on the speed of 30; 40; 50 (Km/h) for Horizontal areas; Longitudinal and vertical based on time domain on line travel Toll-free from Belawan-Tanjung Morawa. Measurement of the overall response of vibration on engine block buffer tube mixer for diesel-fueled trucks molen capacity 3m3, 5m3 at a speed of 30 .40, 50 km/h axial direction, vertical and horizontal obtained the largest Deviations obtained at capacity 5m3 horizontal direction with the highest price 138 x 10-6 m (138 μm) at a time when seconds to 44 with a speed of 50 km/h lowest price, while the axial direction 4.5 x 10-6 m (4.5 μm) at the time of 12 seconds to speed of 30 km/h on the capacity 5m3. The greatest speed is obtained at 5m3 capacity horizontal direction represents the highest price 5.47 mm/sec at the time seconds to 44 with a speed of 50 km/h, while the lowest axial direction of 0.1 mm/sec at a time of 12 seconds to a speed of 40 km/h. The greatest acceleration is obtained at capacity 3m3 horizontal direction represents the highest price of 5.30 mm/sec2 at the time of seconds to 40 with a speed of 50 km/h, while the lowest horizontal direction 1.55 mm/dtk2 at the time of 12 seconds to a speed of 30 km/h at 5m3 capacity. So From standard ISO 10816-3 for the price of 5.47 mm/sec velocity vibration on engine block buffer tube mixer for diesel-fueled trucks molen capacity 3m3, 5m3 with the category of heavy machinery (large) included in Zone B young, green vibration from the engine well and can be operated without restrictions.
