… development is prioritized. The master thesis regards sound reductionof the hydraulic system on a wheel loader. The background to the master thesis is asimulation made on the hydraulic system, performed autumn 2005. The result of the simulationshows that the energy of the …
Hägglunds Drives in Mellansel, Sweden, manufacture radial piston hydraulic motors foremost within applications in the industry. These motors have several sliding contacts, one of these, is the contact between piston ring and cylinder bore. The radial piston hydraulic motors …
… of Statkraft Sweden AB who wants to explore the possibility of replacing the hydraulic cylinder with an electric actuator, generally as well as a case of a small power station on the river Nissan. Whether it is the chaplain or francis turbine vanes are actuated by hydraulic …
… the Company AB, which is currently in a growth phase. The company manufactures hydraulic systems for the heavy vehicle industry and has annual sales of approximately 250 MSEK with 165 employees. The rapid growth and unchanged planning is the starting point for this report. It …
… concepts were evaluated and one concept was chosen. The chosen solution uses hydraulics as source of power. Two hydraulic cylinders are placed between the rolls, one close to each gable. The hydraulic cylinders pull the rolls together. The forces in the gables are reduced since …
… were shaft dimensions, bearings, head shape, tripod, support function and hydraulic cylinder for the capstan and support.Some of the calculations have been made in Ansys. Directional deformation, Von Mises stress for the shaft, length of the hydraulic cylinder in the capstan …
… for compressive and tensile strength tests. They wanted to do this by using a hydraulic cylinder, which they already possessed, to apply the force with. This required a load receiving structure. The aim of this work was to design and dimensioning a test bench for a cylinder …
… on a shaft. Instead the torque is calculated from the oil pressure in the hydraulic cylinders which manages the application of simulated resistance of the propeller shaft. This simulated resistance is created by hydraulic cylinders, belts and pulleys that are stretched and …
… with a smaller S-feeder with pressure. The pressure is achieved by two hydraulic cylinders and a leveler on the upper frame. For proceeding design of the strip feeder so will it be designed for 1,5 against the highest possible strip force that have been calculated during the …
… alternative with manual adjusting and assembly demands a reconstruction of the hydraulic system so that its functions meets the demands that are needed to realize the proposed solution. The advantage with this proposition is that the operator always has the possibility to affect …

… transmissionsolutions and provides repair serviceof hydraulic components. When a hydraulic cylinder is about tobe repaired it needs to bedisassembled. Because hydrauliccylinders usually work in dirtyenvironments and are heavilyworn some types of cylinders arealmost impossible to …
Examensarbete utfördes på CA-Verken i Sävsjö som bl.a. tillverkar hydraulcylindrar. De senaste två år har CA-Verken haft en kraftig ökning av omsättningen och det som står i vägen för fortsatt expansion är produktionen som har begränsad kapacitet. Målet med detta arbete är att …
… The initial conditions were to create an accessory thatcan be run with the hydraulics of the forklift truck. The gadget would be dimensioned in accordancewith an EU-pallet to allow use on most counterbalance trucks. By following the product developmentprocess as taught at …
… Fluida och mekatroniska system vid Linköpings universitet i uppdrag åt Sunfab Hydraulics AB. Höga ljudnivåer är en stor nackdel vid användning av hydrauliska system. Ofta är det hydraulmaskiner av deplacementtyp som står för en stor del av ljudemissionerna. Eftersom maskinerna …
… have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system. Conventional strategies used to raise the exhaust temperature were also tested and compared to the valve strategies developed in this project. The results show that …
