  1. 1. Modelling, failure modes prediction and optimization of gear shifting mechanism, Application to heavy vehicle transmission systems

    Författare :Muhammad Irfan; Chalmers University of Technology; []
    Nyckelord :failure modes prediction.; gear shifting; GT-Suite modelling; optimization; Synchronizer; constrained Lagrangian formalism; sensitivity analysis;

    Sammanfattning : The transmission system has a key role to drive a vehicle transmitting power from engine to rotational motion at wheels. Gear shifting mechanism inside the gearbox is a crucial part of the transmission system. LÄS MER

  2. 2. Modelling and optimization of gear shifting mechanism, Application to heavy vehicles transmission systems

    Författare :Muhammad Irfan; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pareto optimization; synchronization; constraint Lagrangian formalism; sensitivity analysis; Generic synchronizer;

    Sammanfattning : Without an efficient transmission system the idea of an efficient vehicle is incomplete. During running of the vehicle especially in case of heavy vehicles the transmission system has to face different situations during which the system possibly can lose its efficiency. LÄS MER

  3. 3. From LOTOS specifications to distributed implementations

    Författare :Peter Sjödin; RISE; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This Thesis presents a technique for automatic generation of implementations from their formal LOTOS specifications. The technique focuses on implementations executing in distributed systems where processes communicate by asynchronous message passing. Implementations are specified in an executable subset of LOTOS.

  4. 4. Towards model-based development of heavy truck synchronizers

    Författare :Daniel Häggström; Ulf Sellgren; Pär Marklund; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synchronization; synchronizers; gear shift; gearbox;

    Sammanfattning : Gear shifts are becoming more and more important as engines are adapted to low speed and high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to future engines and thus new working conditions, improved development tools are needed. LÄS MER

  5. 5. On synchronization of heavy truck transmissions

    Författare :Daniel Häggström; Ulf Sellgren; Stefan Björklund; Anders Hedman; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synchronization; synchronizers; gear shift; gearbox; synkronisering; växling; växellåda; Machine Design; Maskinkonstruktion;

    Sammanfattning : Gear shifts are becoming more and more important as engines are adapted to low speed high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to new working conditions due to adaptations to new engines, improved development tools are needed. LÄS MER
