Centrifuge Model Tests on Instability of Automotive Pile Drivers
The automotive pile driver is a piece of large-scale construction machinery. This machinery is used for ground improvement and foundation work. In recent years, there have been some reports of accidents in which the machinery overturned. In this study, a 1/25 scale model of an automotive pile driver was made to clarify the mechanism making the pile driver unstable, and centrifuge tests were performed. The load of each axle and the behavior of the model were measured in a centrifuge test. The grounds used with the model are two types of urethane foam with different strengths, with conditions imitating the uniform ground and non-uniform ground. As a result, the response acceleration did not have a significant difference due to differences in ground conditions. On the other hand, the effect of the ground condition was different in the axle load, and it was possible to evaluable the instability of the automotive pile driver when self propelling.
