  1. 1. On Fluid Power Pump and Motor Design : Tools for Noise Reduction

    Författare :Liselott Ericson; Jan-Ove Palmberg; Kalevi Huhtala; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Noise and vibration are two of the main drawbacks with fluid power  systems. The increasing requirements concerning working environment as well as machines' impact on surroundings put components and systems to harder tests. The surrounding machines, e.g. LÄS MER

  2. 2. Mobile Fluid Power Systems Design : with a Focus on Energy Efficiency

    Författare :Björn Eriksson; Jan- Ove Palmberg; Heikki Handroos; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This work deals with innovative energy efficient fluid power systems for mobile applications. The subjects taken up concern to what extent and how energy losses can be reduced in mobile working hydraulics systems. Various measures are available for increasing energy efficiency in these kinds of systems. LÄS MER

  3. 3. Operator and Machine Models for Dynamic Simulation of Construction Machinery

    Författare :Reno Filla; Jan-Ove Palmberg; Jonas Larsson; Allan Ericsson; Tobias C. Larsson; Linköpings universitet; []
    Nyckelord :dynamic simulation; construction equipment; discrete simulation; continuous simulation; operator model; driver model; integrated product development; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : VIRTUAL PROTOTYPING has been generally adopted in product development in order to minimise the traditional reliance on testing of physical prototypes. It thus constitutes a major step towards solving the conflict of actual increasing development cost and time due to increasing customer demands on one side, and the need to decrease development cost and time due to increasing competition on the other.

  4. 4. Quantifying Operability of Working Machines

    Författare :Reno Filla; Jan-Ove Palmberg; Kjell Ohlsson; Jonas Larsson; Linköpings universitet; []
    Nyckelord :Operability; machine harmony; operator workload; control effort; simulation; operator model; human operator; working machines; construction equipment; wheel loaders; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : In working machines the human operator is essential for the performance of the total system. Productivity and energy efficiency are both dependent not only on inherent machine properties and working place conditions, but also on how the operator manoeuvres the machine. LÄS MER

  5. 5. On Energy Efficient Mobile Hydraulic Systems : with Focus on Linear Actuation

    Författare :Kim Heybroek; Petter Krus; Jan-Ove Palmberg; Torben Ole Andersen; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In this dissertation, energy efficient hydraulic systems are studied. The research focuses on solutions for linear actuators in mobile applications, with emphasis on construction machines. Alongside the aspect of energy efficiency, the thesis deals with competing aspects in hydraulic system design found in the development of construction machines. LÄS MER
