F-1406 Modeling of running equipment with a bogie mechanism in crawler-type construction machine and the traveling simulation

Abstract

Bogie mechanism etc. have become to be used for running equipment of crawler-type construction machine to improve the comforts. However, in the running equipment, there are many unclear points in the behavior and loads due to the complicacy. This paper shows a method for modeling of crawler-type running equipment with a bogie mechanism as a multibody system. And the treatment of the contact between grousers and rigid ground like steel plate, etc. is shown. The dynamic behavior of running equipment such as the suspension forces in traveling on horizontal and stepped ground is calculated by the traveling simulation using this model. It is possible to obtain the data required in the limit state design for running equipment by this method.
