New concepts of vehicles, modelling and simulation using WMI and MG20 vehicles as an example

Paper presents the problems connected with designing new concept vehicles for defence industry as well as modelling and simulation methods issues on the basis of WMI and MG20 vehicles. Project development process of MG20 vehicle laying kit, separate analysis phases starting from kinematics sketch and development of concept model of the system through strength computation of structure, ending with development of working documentation and vehicle model execution were presented. The concept of modern Multi-task Engineering Machine provided for engineering troops was presented in this work. Execution of tasks on modern war theatre, during intervention and peace missions as well as during natural disasters effects counteractions requires a specialistic engineering equipment adapted for special military and civil demands. High mobility and versatility are the main parameters that feature this equipment. Within the scope of operational needs review, the need to deploy the Multi-task Engineering Machine to engineering troops, which is to substitute old-fashion and very used single-task machines used up to now. Disused structures of engineering machines used in Polish Military Forces during recent decades had large weight and low versatility. Their structures were based of heavy, deceptive and high operation cost the drive systems. Engines of low efficiency, hard to maintain and servicing the drive transmission systems made difficult common application and execution of engineering works. The greatest disadvantage of engineering vehicles that are used by Polish Military Forces is low mobility. This causes significant difficulties to transport a vehicle to the location where works and tasks are being carried out, frequently of distance several hundred kilometres (for instance, while removing natural disasters effects)
