Abstract
This paper describes the results of a study of the effects of articulation joint configuration, suspension characteristics, location of the centre of gravity and initial track tension on the mobility of a two-unit, articulated tracked vehicle. The study was carried out using a comprehensive computer simulation model known as NTVPM-86. The results show that suspension characteristics, location of the centre of gravity and initial track tension have noticeable effects on the mobility of articulated tracked vehicles over marginal terrain, while the articulation joint angle has a less significant influence on vehicle performance. Locking the articulation joint between the two units of an articulated tracked vehicle usually causes a degradation of tractive performance. The approach to the optimization of the design of articulated tracked vehicles is demonstrated. It is shown that the simulation model NTVPM-86 can play a significant role in the optimization of articulated tracked vehicle design or in the evaluation of vehicle candidates for a given mission and environment.Keywords
