The purpose of the article is to present a point of view on determining the mass moment of inertia coefficient of a tracked vehicle. This coefficient is very useful to be able to estimate the performance of a tracked vehicle, including slips in the converter. Determining vehicle acceleration plays an important role in assessing vehicle mobility. Additionally, during the transition from the Hydroconverter to the hydro-clutch regime, these estimations become quite difficult due to the complexity of the propulsion aggregate (engine and hydrodynamic transmission) and rolling equipment. The algorithm for determining performance is focused on estimating acceleration performance. To validate the proposed model, tests were performed to determine the equivalent reduced moments of inertia at the drive wheel (gravitational method) and the main components (three-wire pendulum method). The dynamic performances determined during the starting process are necessary for the validation of the general model for simulating the longitudinal dynamics of the vehicle. Finally, the differential and algebraic equations of the virtual model approximate more accurately the actual process of the operation of the vehicle. The virtual model, through the data obtained from the simulation process, allows for the determination, indirectly, of the variation of the mass moment of inertia coefficient and its expression of approximation.
本文旨在提出一种确定履带式车辆转动惯量系数的观点。该系数对于评估履带式车辆的性能非常有用，包括变矩器中的滑转。确定车辆加速度在评估车辆机动性方面起着重要作用。此外，在从 Hydroconverter 向 Hydro-clutch 模式过渡期间，由于推进组件（发动机和液力传动）和滚动设备的复杂性，这些估算变得相当困难。确定性能的算法侧重于估算加速度性能。为了验证所提出的模型，进行了测试以确定驱动轮（重力法）和主要部件（三线摆法）的等效减小转动惯量。在启动过程中确定的动态性能对于模拟车辆纵向动力学的通用模型的验证是必要的。最后，虚拟模型的微分和代数方程更准确地近似实际车辆操作过程。通过仿真过程获得的数据，虚拟模型可以间接确定转动惯量系数的变化及其近似表达。
