The Powertrain Dynamics Library (PTDynamics) has been developed using a new approach to modelling the mechanics of rotating MultiBody systems. This paper will highlight the recent developments within the PTDynamics library with a focus on the dynamic torque converter and wet clutch models that enable the prediction of the launch feel of automatic and dual clutch transmission equipped vehicles. ...

A promising direction in developing up-to-date transport vehicles is the use of transmissions, an essential element which a dual-clutch. Improving functional performance, energy efficiency, and environmental friendliness are relevant require appropriate research. The object study dry dual-clutch working with manual transmission high efficiency. In proposed design scheme, rotary lever movable ca...

Climate change is expected to affect temperature and precipitation means and extremes, which can affect population vital rates. With the added complexity of accounting for both means and extremes, it is important to understand whether one aspect is sufficient to predict a particular vital rate or if both are necessary. To compare the predictive ability of climate means and extremes with geograp...

Increasing demands on comfort, performance, and fuel efficiency in vehicles lead to more complex transmission solutions. One such solution is the Automated Manual Transmission (AMT). It works just like an ordinary manual transmission but the clutch and the gear selection are computer controlled. In this way high efficiency can be accomplished with increased comfort and performance. To be able t...

The performance of an automatic transmission is dependent on the dynamics its components, such as clutch, planetary gear, and torque converter. In particular, clutch pressure gear output speed can affect overall transmission. this paper, It will present kinematic relations, structure, calculating impact braking brake to slip vehicle Toyota Camry used A140L. Since then, graph describing dependen...

Theories of clutch size determination have focused on first broods or on seasonal trends in clutch size. Clutch size is controlled by combination of genetic, ontological and environmental factors (KENNEDY & WHITE, 1991). In recent years, an increasing number of studies have demonstrated the existence of significant repeatability in ecologically important traits in natural bird populations (e.g....

In this paper, we have reported results of the experimental tests for validating and characterizing a new design and its operation for a humanoid robot arm with one actuator only. The core of the arm system consists of clutches that are activated or deactivated according to a programmed manipulation path-planning. Experimental tests are discussed with measured results to characterize the functi...

In this paper we extend previous control design applied to an electropneumatic clutch actuator. A dual-mode switched nonlinear controller design and an adaptive nonlinear observer design are combined to achieve position control of the clutch actuator with only position measurements available. The observer provides estimates of position, velocity, chamber pressures, friction state and parameters...

This paper proposes a novel hybrid power system to improve the shift quality of electric vehicle (HEV). After selecting typical scheme, study focused on motor rotary velocity control algorithm and coordinated strategy for clutch. The effects various algorithms different target velocities were analyzed, proportional-integral-derivative (PID)–bang-bang–fuzzy compound intelligent was investigated....
