Abstract The article focuses on overcoming the limitations of contact methods for measuring the dynamics of tracked vehicles. As a solution, a method is proposed which is based on non-contact measurement of track link displacements using high-speed videography and computer vision algorithms. The implementation of the Lucas–Kanade optical flow, an efficient algorithm for tracking feature points on the surface of the track links, is discussed in detail. It is shown that this approach allows for highly accurate measurement of displacements, velocities, and deformations along the entire track loop without affecting the object of study, meeting the stringent requirements of experimental research. The method enables high-precision identification of frequencies, amplitudes, damping coefficients, and vibration modes of various track branches and provides a complete picture of the kinematics of the track loop branches without influencing the object under study.
Keywords caterpillar drive, dynamics, oscillations, amplitude, frequency, computer vision, Lucas–Kanade optical flow method

Abstract The paper considers scientific and engineering aspects of design, optimization, calculation, construction and ensuring manufacturability of production of drive axles of heavy-duty quarry dump trucks. A new method of engineering analysis has been developed for express assessment and limitation of the selection area of the main parameters of gear transmissions of drive axles of BELAZ quarry dump trucks: gear module; number of gear teeth; load on input (output) shafts; maximum rotation frequency of input (output) links; maximum dynamic factor. Distribution of the drive axle gear ratio uвм is made according to the principle of maximizing the torque in the final stage, i.e. in the planetary wheel transmission, which reduces the loads on the differential and axle shafts and their dimensions. When distributing gear ratios, it is necessary to take into account the limitations of ensuring the technological possibility of cutting teeth of bevel gears with a circular tooth of the main transmission on the equipment available at the enterprise. For the first time, the Bbha scheme of a single-row planetary wheel reduction gear with a double-crown satellite has been used on BELAZ extra-large-capacity quarry dump trucks. The adopted design provides an increase in the gear ratio by 1.7...1.8 times compared to a single-row classic Abha planetary reduction gear.

Abstract The article considers the generally accepted kinematic theory of calculation of planetary mechanisms, based on the principle of equivalence of the real and reversed mechanisms (Willis method). The paper proposes evaluation criteria (relative angular velocity of the satellite; number of satellite teeth engaged with the central wheel per unit of time) that prove, using specific examples of calculating a planetary mechanism and its reversed versions (planetary with zero inversion and differential with arbitrary inversion), the equivalence of the real kinematic scheme and its virtual states. A universal equation is also provided for determining the rotation angles of the satellite during one revolution of the sun gear. An algorithm is given for distributing circumferential forces and their reactions in the engagement of the satellite and central wheels based on the Archimedean lever. The paper considers the issues of complex rotational motion of a planetary mechanism’s satellite, determines the relative and absolute gear ratios between the mechanism’s links, and calculates the satellite’s force balance.
Keywords planetary series, differential mechanism, Willis method for planetary gears, relative angular velocity, law of lever forces
