| Abstract | This paper examined the development of a real-time weight measurement system for sugarcane harvesting. Finite element simulation of the behavior of the load of harvested sugarcane in the bin box acting on the truck chassis was established. The position of the weight sensors was determined using stress distribution results, and the weight sensors were then designed and constructed. A testing unit representing the truck chassis was constructed for the calibration of the weight sensors. The results showed that sensors should be installed for weight measurements on the chassis at 180 mm above the rear wheel mounting position, where the maximum stress was 7.64 MPa. The designed weight sensor consisted of four strain gauges attached to the end of two 30 mm diameter bolts. All strain gauges were wired into a Wheatstone bridge circuit (full bridge). From the calibration results, the linear relationship between the produced signals from sensor (X) and weight (Y) was determined at Y = 0.0002X +2.1283, and R? = 0.9061. |
