The torque converter is connected to a mean-value engine model, transmission model, and longitudinal dynamics model in the maplesim environment, which uses the advantages of an acausal modeling. Academiaedu is a platform for academics to share research papers. The proposed model is a math-based dynamic model of a torque converter, based on the paper by hrovat and tobler, which includes both transient and steady state behavior of the torque converter.

The torque converter is placed between the internal combustion engine and the gearbox an automatic transmission, inside its case, contains three main parts: the torque converter, the epicyclic (planetary) gearbox and the electro-hydraulic control module. A theoretical procedure is described to predict the performance characteristics of torque converters with three elements the mathematical model is developed assuming that the circulation motion of the fluid is similar to a forced vortex with a linear velocity distribuition from the mean radius. For hydraulic torque converter with overtaking clutch always and blocking comes at, therefore blocking conditions of pump and turbine wheels for hydraulic torque converter (19) have some formal differences from blocking conditions of a friction clutch (15. If you are building a racecar and need to pick the correct torque converter, start with the class you want to race or the bracket you want to compete in and work backward from there.

Math based torque converter clutch slip table calibration peer reviewed conference papers 2016 robinette, d and blough, j “transient heat transfer and energy balance model for hydrodynamic torque converters while operating at extreme speed ratios”, isromac 16, honolulu, hi, april 2016. Torque converter model the torque converter is a mechanism for transferring torque between impeller and turbine shafts because the coupling of i and t occurs by viscous action, the torque transfer depends on the difference ω = ω t – ω i ≠ 0 , or the speed ratio r ω ≠ 1. The torque converter is but one part of the system that you must understand if you are to work successfully in the transmission repair scene if you want to be able to diagnose and repair an automatic transmission , you must become knowledgeable about transmissions overall.

Math–based torque converter modelling to evaluate damping characteristics and reverse flow mode operation this paper presents math–based torque converter modelling and simulation in both forward flow mode and reverse flow mode operations. Torque converter physics discussion in 'ideas and another issue is the non linear transfer of torque with slip that a torque converter has, the viscous clutch model lacks this so i am sharing this explanation and a couple of papers describing the functioning of a torque converter papers: math-based torque converter modelling to.

The main focus of this research is on reverse flow mode simulation, and the application of the proposed math-based torque converter model to evaluate damping characteristics of a torque converter due to undesired disturbances generated either from engine pulsations or from road bumps and potholes. The 330e combines the 20-liter gasoline turbo four from the 320i starter model with a powerful electric motor that generally contributes 87 horsepower and 74 pound-feet of torque—and up to 184. The torque converter block implements a three-part torque converter consisting of an impeller, turbine, and stator with an optional clutch lock-up capability the block can simulate driving (power flowing from impeller to turbine) and coasting (power flowing from turbine to impeller.

• the engine feeds torque to the transmission either through a hydraulic torque converter or through a mechanical clutch aligning moment which can be defined as nonlinear functions of tire compression. A theoretical procedure is described to predict the performance characteristics of torque converters with three elements the mathematical model is developed assuming that the circulation motion of the fluid is similar to a forced vortex with a linear velocity distribuition from the mean radius (r v. Of the proposed math-based torque converter model to evaluate damping characteristics of a torque converter due to undesired disturbances generated either from engine pulsations or from road bumps and potholes. This study investigated the influence of the inlet deflection angle on the performance of torque converters and a method of optimizing the inlet deflection angle for torque converters based on 3d flow simulation is presented.

- The paper includes examples of static torque converter model validation and complete, dynamic model usage in the design of shift quality controllers for discrete ratio electronic transmissions based on this experience, it is concluded that the above model offers a solid basis for future complete validation and experimental work.

“a dynamic model for automotive estimate the input/output torques of the torque converter torque converters,” int j vehicle design, vol 21, nos than the steady-state characteristics of the torque 4/5 (special issue), pp344-354 converter under the transient condition. 1 the mechanics of tension control by jeff damour converter accessory coporation wind gap, pa usa introduction this presentation is a basic tutorial in the mechanics of web tension control. Torque is represented by the greek letter tau, ττ, and the rate of change of an object’s angular momentum equals the total torque acting on it: τtotal=δlδt (if the angular momentum does not change at a constant rate, the total torque equals the slope of the tangent line on a graph of ll versus tt.
