Study on Dynamic Stability of a Truck Crane Carrier : 3rd Report, Approximate Analysis of Forward Stability in Load Lowering Down Motion

抄録

This paper is a continuation to the previous report on the forward stability of a truck crane. The analysis based on a strict simulation model gives precise results but is too complicated for practical use. Here an approximate method using a simplified simulation model is proposed to analyze the behavior of a truck crane overturnings in the direction of the lifted load by sudden stop during load lowering. Thus the minimum acceptable forward stability of a truck crane can be easily determined. Effects of crane specifications and constants on the stability have also been clarified.
