The maintenance system of high-speed military tracked vehicles and the graphic original interpretation of maintenance activity (mainly maintenance) are described. A modification of the maintenance system of the above-mentioned vehicles based on dependability-oriented maintenance (Reliability Cantered Maintenance – RCM) is proposed. Additionally, the use of the statistical analysis of maintenance cases and the development of Computerised Maintenance Management System – CMMC are proposed as well.

The research object is the motion attitude of the high-speed tracked vehicles climbing over the vertical wall. The new calculation method is used in calculating certain parameters of the equation and establishing the equation of driving characteristics. The changing equations of the pitch angle and roll angle when the high-speed tracked vehicles crossing the obstacles can be obtained. The analysis results show that the motion attitude when the high-speed tracked vehicles crossing the obstacles is related to the terrain parameters, the tracked vehicle parameters, the initial velocity when crossing the obstacles, and the motion attitude can be expressed by the mathematics equations. These results provide the research-based and the theory support for the modal and analysis of the high-speed tracked vehicles crossing over the obstacles, which have high practical value.

High power density energy regeneration is one of the effective solutions to solve the contradiction between improving the damping performance and energy consumption of active suspension. The hydraulic commutator is used to realize hydraulic rectification and hydraulic variable speed/pump/motor with few teeth difference gear pairs is used to match the speed, combined with permanent magnet motor power generation and power supply to put forward kilowatt level high power density mechanical-electrical-hydraulic regenerative suspension system for high-speed tracked vehicles. The mathematical model and fluid-solid-thermo-magnetic multiphysics coupling model are built to analyze the damping performance and regenerative characteristics of the system under passive and semi-active working conditions. The simulation results show that the damping force of the system increases with the increase of the road excitation amplitude and the semi-active control can be realized by adjusting the duty cycle with the PWM control rectifier module. The high power density mechanical-electrical-hydraulic regenerative suspension system can realize kilowatt level energy regeneration, and the regenerative efficiency is more than 50% under low-frequency excitation. The temperature rise of the system is low during operation, which is helpful to improve the reliability and service life.

A method for controlling the curvilinear movement of a high-speed tracked vehicle in a skid without loss of stability is proposed. The mathematical model of the vehicle is refined. With the help of simulation modeling, a control algorithm is worked out when driving in a skid. The effectiveness of vehicle steering at high speed outside the skid is shown. Keywords: controlled skid, dynamic stability, steering pole displacement, hydrostatic transmission, automatic system, fuel supply. [email protected]

The steering mechanism of tracked vehicles is complicated and large, which is an obstacle for its miniaturization. According to the theory of rubber-belt CVTs, a new kind of steering mechanism for small Tracked vehicle is designed. The mechanism consists of two symmetrical-layout rubber-belt CVTs. A sliding part for steering is designed, which can slide axially to make the transmission ratio of one transmission increase while the other reduces, so that the tracked vehicle turns. The steering motion is calculated and its motion discipline is founded. The steering sensitivity and steering smoothness are analyzed, and its steering performance is evaluated.

With the advantage of steering performance, articulated tracked vehicles have excellent mobility in off-road application. However, in current models for steering performance, soil deformation on the interaction between track and soil cannot always be taken into account. Therefore, steering performance cannot always be calculated accurately. In order to solve the problem, it is essential to propose a steering model which can take the effect of soil deformation on track–soil interaction into consideration. In this article, a steering model of articulated tracked vehicle is proposed on track–soil interaction. Moreover, in order to improve steering performance, a track–soil sub-model is developed that can consider soil deformation on track–soil interaction. Using this steering model based on track–soil sub-model, steering performance can be calculated more accurately. Simulation studies and experimental results are in strong agreement with the theoretical results in this article. The results show that equipped with the track–soil sub-model, the proposed steering model can be used to accurately predict steering performance. The steering model of articulated tracked vehicle proposed in this article can provide a basis for other similar vehicles.
