“…Chun 4 gave the mathematical models to simulate the flow characteristics of the engine lubrication system and then analyze the flow and pressure distribution of each lubricated components in the flow network. Gu et al 5 built the automotive engine lubrication system in the platform of AMESim to simulate the steady lubricant flow rate and pressure at different engine speed. Klingebiel and Kahlstorf 6 modeled the internal combustion engine lubrication systems using the one-dimensional (1D) fluid Flowmaster software to analyze how much models may differ in order to achieve a reliable result for the different aspects of the system.…”

An accurate simulation model of the lubrication system is essential for early design of the heavy truck transmission. In this article, a detailed computational method for the flow network analysis of the lubrication circuit is developed based on the hydraulic theory, and the flow resistance through the oil pipes and orifices is also taken into consideration. Then, the Next Limit Technologies' XFlow, a potential new three-dimensional computational fluid dynamics software based on lattice Boltzmann method, is adopted to obtain the relationship between the oil delivery and the lubrication effect in the low-pressure capillary lubrication network of the rear auxiliary gearbox. To achieve the best overall lubricating performance of the flow network, the optimized design of the diameter for each oil supply orifice is determined by a detailed sensitivity analysis on the contribution of each parameter to the volumetric flow rate. The bench tests for the volumetric flow rate have been performed for validating the computation model by comparing the predicted volumetric flow rate through each oil supply bore with the experimental data at various pump speeds. The endurance tests have further conducted and the test results indicate a remarkable reduction in mechanical weariness when the best solution of the flow network design for the transmission lubrication system is adopted.

This article presents an analysis method based on lumped-parameters (LP) and computational fluid dynamics (CFD) to evaluate the behavior and calibrate the lubrication (LUB) circuit in an agricultural dual-clutch transmission. Gearbox LUB is crucial because it affects reliability, life, and transmission efficiency. The transmission’s hydraulic circuit consists of the higher pressure power transmission control and actuation circuit and the low pressure LUB circuit. The former was analyzed with LP approach, instead the latter was modeled with CFD approach due to its geometric complexity. The results will be contextualized by commenting on the advantages and limitations of LP and CFD analysis, finally outlining a mixed analysis methodology. The simulations are solved for different engine speed. The results are used to calibrate a comprehensive LP model (model) and to optimize the LUB circuit by adjusting some critical design parameters. As an experimental approach, simplified tests are usually performed ignoring the action of the centrifugal force, which has a great impact on the flow regime inside the LUB ducts. This work aims to develop a methodology for analyzing LUB in all parts of the gearbox, which can help designers test various combinations within industrial timeframes and obtain reliable and the most efficient configuration.
