The automotive marketplace has seen a steady increase in customer demands for quiet and more comfortable vehicles. A customer’s expectations for NVH refinement often contradicts the constraints for lightweight vehicle designs and the need for a powertrain with increased fuel efficiency. The driveline of a vehicle can be a substantial cause of NVH issues. Variants in the driveline architecture (...

A vehicular driveline is the system used to transfer engine torque to the wheels. Resonances in the elastic parts of the driveline are important to handle when control of the engine and the transmission is optimized. Gear shifting by engine control is a new approach for automatic gear shifting with disengaging the clutch replaced by engine control. Resonances are excited in an uncontrolled driv...

A 48 year old patient with dilated cardiomyopathy and chronic acne inversa underwent implantation of a LVAD system (Heartmate II, Thoratec, USA) March 2011. During 2011 and 2012 the patient was repeatedly readmitted for treatment of driveline infection with MRSA. Colonization was controlled with Linezolid and Rifampicin however reoccurred after discontinuation. In August 2012 the LVAD-system wa...

Figure 3 Known potential and limitations of driveline optimization (Ref. 2). Management Summary In today’s motor vehicles, an optimally designed driveline provides substantial CO2 reduction. Different transmission systems, such as manual transmissions, torque-converter transmissions, dual-clutch transmissions, CVTs and hybrid systems, work better with different requirements and vehicle classes....

vehicle driveline system and its working accuracy play an important role in the performance of car. the purpose of this study is to provide an appropriate mechanism for investigating, identifying and determining the position and size of defects in the vehicle power transmission system. this is based on the patterns of the residual signal, obtained from a simulated model of the system. neuro-fuz...

We report the case of a 64-year old Caucasian male patient with a tear of the left ventricular driveline just above the driveline-air tube junction. We describe the repair technique and the necessary set of tools.

Results 82 (77.4 %) patients were without infection, 7 (6.7 %) patients developed pump-pocket infection and in 17 (16 %) patients occurred driveline infection. Patients were divided according to driveline technical implantation to three groups: 58 patients with classic/direct technique, 12 patients with „C-shape techniquevelour coated“ and 36 patients with „C-shape technique plastic exit site“....

Staphylococcus epidermidis remains the predominant pathogen in prosthetic-device infections. Ventricular assist devices, a recently developed form of therapy for end-stage congestive heart failure, have had considerable success. However, infections, most often caused by Staphylococcus epidermidis, have limited their long-term use. The transcutaneous driveline entry site acts as a potential port...

OBJECTIVES To determine if driveline infection is related to dressing change frequency in hospitalized adult patients with newly implanted left ventricular assist devices (LVAD). BACKGROUND Guidelines do not exist for the frequency of driveline exit-site dressing change in hospitalized patients resulting in wide variation in practice. METHODS A retrospective chart review was conducted on 68...

The paper presents an overview of the bond graph models of advanced automotive transmission and driveline systems. This includes one-mode and two-mode series-parallel hybrid electric vehicle transmissions, a continuous variable transmission, active-limited slip and torque vectoring differentials in 2WD and 4WD configurations, and electromechanical actuator-based wet and dry clutch actuation sys...
