  2. 1. Flow Pulsations in Fluid Power Machines - a Measurement and Simulation Study

    Author : Liselott Ericson; Linköpings universitet; []
    Keywords : noise; pump; motor; measurement; optimisation; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Stricter requirements for better working environment involve noise and vibration control of hydraulic machines. The operational conditions for hydraulic machines, such as pressure and rotational speed, are also increasing and this makes it even more difficult to develop a quiet, vibration-free machine due to the interdependence between noise and escalating operational conditions.

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

    Author : Liselott Ericson; Jan-Ove Palmberg; Kalevi Huhtala; Linköpings universitet; []
    Keywords : ;

    Abstract : 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. READ MORE

  5. 3. Simulation-Based Optimization of a Series Hydraulic Hybrid Vehicle

    Author : Katharina Baer; Petter Krus; Liselott Ericson; Seppo Tikkanen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Hybrid transmissions are characterized by their utilization of more than one form of energy storage. They have the potential to help reduce overall fuel consumption and vehicle emissions by providing the possibility of brake energy recuperation and prime mover operation management. READ MORE

  6. 4. Design of Electro-Hydraulic Energy Converters : With Focus on Integrated Designs and Valve Plate Rotation

    Author : Thomas Heeger; Liselott Ericson; Andreas Johansson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In mobile working machines, there is a trend towards replacing combustion engines by electric machines to reduce their carbon footprint. This provides several advantages and challenges for the hydraulic system. The low efficiency of conventional hydraulic systems is no longer acceptable due to the volume and cost of batteries.

  7. 5. Fluid Power Pumps and the Electrification : With a Focus on Discrete Displacement Control in Load Handling Applications

    Author : Samuel Kärnell; Liselott Ericson; Petter Krus; Maria Pettersson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : More and more vehicles are being electrified. Mobile working machines and heavy trucks are not excluded, and these machines are often hydraulically intense. Electrification entails new requirements for the hydraulic system and its components, and these requirements must be taken into consideration. READ MORE
