  1. 1. On the Load Distribution and Design of a Chain Drive

    University dissertation from Machine Elements Division, P.O.Box 118,SE- 22100 Lund,Sweden

    Author : Ingvar Troedsson; Lunds universitet.; Lund University.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tension force; tensioner; oscillation; chain drive; vibration; load distribution; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Abstract : Three methods are presented to calculate the load distribution in a chain drive containing two sprockets and one chain. The rollers, which are in contact with the sprockets, can move along the tooth flanks and their positions are given by force equilibrium. READ MORE

  2. 2. Volunteer Muscle Activity in Dynamic Events. Input Data for Human Body Models

    University dissertation from Machine Elements Division, P.O.Box 118,SE- 22100 Lund,Sweden

    Author : Jóna Marin Olafsdottir; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; emergency braking; ative human body model; multidirectional perturbations; EMG; occupant kinematics; seatbelt pre-tension; reflex; validation data;

    Abstract : Human body models (HBMs) are virtual human surrogates used to predict kinematic and injury responses during motor vehicle crashes. In recent years, active musculature has been incorporated into HBMs for enhanced biofidelity in simulated emergency scenarios, in particular low-severity crashes and pre-crash situations, where occupant responses are influenced by muscle tension.

    Abstract : Popular Abstract in Swedish Kontrollmekanismerna rörande blodcirkulationen i den mänskliga fetoplacentära enheten är fortfarande inte fullständigt kända, trots genomgripande undersökningar. Det är dock känt att den är viktig för att kunna bibehålla en normal graviditet och för att kunna frambrigna ett friskt nyfött barn. READ MORE

  4. 4. Muscle Responses in Dynamic Events. Volunteer experiments and numerical modelling for the advancement of human body models for vehicle safety assessment

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Jóna Marin Olafsdottir; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pre-crash dynamics; spatial tuning patterns; occupant kinematics; electromyography.; Traffic safety; muscle activity; human body models;

    Abstract : Fatalities and injuries to car occupants in motor vehicle crashes continue to be aserious global socio-economic issue. Advanced safety systems that provide improvedoccupant protection and crash mitigation have the potential to reduce this burden. READ MORE
