Hardware in the loop simulation of a gas compressor

The Quintus Hot Isostatic Press is used to reduce the porosity of metals and increase the density of many ceramic materials to improve their mechanical properties. A Quintus HIP can deliver pressures up to 2000 bars and temperatures in the excess of 1400°C. To reach these pressures a hydraulic unit is powering a pressure intensifier to compress the gas in a pressure vessel.

Background

The hydraulic unit consists of an axial piston pump that drives a double acting pressure intensifier that compresses gas in two stages. It is split in a low-stage compression and a high stage compression both driven by the same hydraulic piston with interstage and after-stage coolers. The hydraulic unit itself consists of two directional control valves that control the stroke of the hydraulic position.

Task description

The goal of the thesis is to create a simulation model, verify the model and create a hardware in the loop. Test equipment is available for verification. The focus areas are:

  • Build a system model in Amesim. Verify with real data.
  • Optimize the switching of directional control valves.
  • Build an interface to create a hardware in the loop between system model and a PLC.

Suitable background

Mechanical Engineer in fluid power, mechatronics or similar.

  • A basic understanding of fluid principles, common components, and terminology.
  • Control theory knowledges and applications, model building and implementations.
  • Experience with simulation software, such as Hopsan, AMESIM, Matlab/Simulink.

Application Information

The thesis will take place at Quintus office in Västerås and is aimed for one or two persons. The selection will be ongoing so therefore apply as soon as possible. Send your CV and grades to recruitment@quintusteam.com
