The historical developments in the discipline of engineering dynamics are brie¯y reviewed, with attention paid to the formulation and solution of the dynamic behaviour of multi-body systems. It is shown that the dynamic characteristics of practical multi-body systems are dependent upon the interactions of many physical phenomena that can induce, restrain or constrain motion of parts. The long process of understanding and formulating the physics of multi-body motions, in some cases with pioneering contributions centuries old, together with continual re®nements in numerical techniques and enhanced computing power has resulted in the solution of quite complex and practical engineering problems. Linking the historical developments to the fundamental physical phenomena and their interactions, the paper presents solutions to two complex multi-body dynamic problems. The practical implications of the approach in design of these systems are highlighted.

Abstract. ŠKODA VÝZKUM s.r.o. cooperated on the development of the NEOPLAN DMA low-floor articulated trolleybus intended for the Boston city. Multibody models and finite element models of the trolleybus were utilized in the stage of the vehicle design. At the end of the stage of computer modelling and testing of the trolleybus prototype a decision to reduce tire inflating of vehicles in serial production (together with the change the type of shock absorbers used in trolleybus suspension) was made. The impact of this change on forces acting in the trolleybus suspension elements (i.e. in air springs and shock absorbers) and radius rods on the trolleybus chassis when running on an uneven test track was investigated using multibody simulations. Time histories of the forces calculated utilising multibody models were used as input data of the trolleybus finite element models.

“…Consequently, the load-deformation relationship of the oil sand terrain cannot be predicted exactly by the static model. To overcome the limitations of the static model, a dynamic model [9] has been proposed to model and simulate a tracked vehicle moving on soil.…”

“…The model comprises two sub-systems: carriage model and oil-sand model. The carriage model is an eight-DOF multi-body system; six DOFs are introduced by the basic Newton-Euler rigid body model accounting for the dynamics of vehicle body [9] and the other two DOFs are introduced by the revolute joints connecting the carriage to two sprockets. Two torques are applied to the sprockets through two revolute joints.…”
