“…e estimation performance demonstrates the feasibility of online and real-time track tension monitoring based on the remotely measurable signals such as tensioner position and pressure, sprocket angular velocity, vehicle velocity, and acceleration. In Chalupa et al [6], a method is introduced to establish the kinematic mechanism model of tracked vehicle in simulation system, which consists of two parts: geometrical part and contact computational part. e purpose of the simulation is to analyze the influence of changes in track constructive parameters on track vehicle course stability.…”

The deep-sea mining miner requires good passability to operate in complex and changeable terrain environment of the seabed. Among them, the track tension is an important factor to ensure the normal running of the vehicle. Aiming at the complex track tension problem on track link, the forces on each component of the tracked system were analyzed, and the theoretical formulas of track tension were established. The theoretical estimation and dynamic simulation of track tension in uniform speed were carried out by using the multibody dynamics model of the tracked vehicle, and the rationality of the theoretical estimation formula was verified. The influencing factors of track tension also were analyzed, and the significance of each factor on track was discussed by dynamic simulation. The results provided a theoretical basis for design of tracked vehicles.

Computational modelling and simulations are nowadays widely used for design of railway vehicles, analysing and assessment of their dynamic properties and also for detection and prediction of the mechanism of deterioration and sources of damages. Therefore it is necessary to develop the adequate virtual model of an analysed railway vehicle as well as a track. For these purposes many simulations software packages are developed. In these computational programs a railway vehicle is modelled as a mechanical system usually consists of many bodies called a multibody system. In this paper the process of computational modelling of a freight wagon multibody system is outlined. Moreover, there are presented also results of dynamic simulation of a freight wagon running on a real track section. The analysed intermodal freight wagon was equipped with Y25 bogie. The freight wagon model, simulation analyses and ride properties evaluation were performed by means of a commercial simulation program.

ŠKODA VÝZKUM cooperated on the development of the NEOPLAN DMA low-floor articulated trolleybus intended for the Boston city (the United States). Multibody models and finite element models of the trolleybus were utilized in the stage of the vehicle design. The multibody models of the trolleybus were created in the alaska simulation tool and the simulations were especially aimed at determining forces acting in the trolleybus suspension elements and radius rods. At the end of the stage of computer modelling and testing the trolleybus prototype a decision to change the type of shock absorbers used in the axles´ 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. Stress in the critical places of the trolleybus body structure was determined utilizing the finite element models.
