  1. 1. Predictive Maintenance of Construction Equipment using Log Data : A Data- centric Approach

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Bazil Muzaffar Kotriwala; [2021]
    Nyckelord :Predictive Maintenance; Construction Equipment; Event Log; Sensor Log; Machine Learning; Imbalanced Data; Prediktivt underhåll; byggutrustning; händelselogg; sensorlogg; maskininlärning; obalanserade data;

    Sammanfattning : Construction equipment manufacturers want to reduce the downtime of their equipment by moving from the typical reactive maintenance to a predictive maintenance approach. They would like to define a method to predict the failure of the construction equipment ahead of time by leveraging the real- world data that is being logged by their vehicles. LÄS MER

  2. 2. Smart components : Creating a competitive edge through smart connected drive train on mining machines

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :KAJOL SINGH; [2021]
    Nyckelord :Drivetrain; downtime; sensor system; operating data; planned maintenance; spare parts inventory; Drivlina; stillestånd; givarsystem; driftsdata; planerat underhåll; reservdelsinventering;

    Sammanfattning : Major drivetrain components of the Epiroc machines like axles, gearboxes, transmission, torqueconverter, clutch, and bearings are critical components which are focused upon in this thesis. Failure of these major component results in breakdown of the vehicle and if early fault detection is not existing, then this causes engineers and technicians to spend a substantial amount of time to identify the root cause of the failure.

  3. 3. 3D Printed Lattice Structure for Driveline Applications

    Master-uppsats, KTH/Materialvetenskap

    Författare :Boyu Xue; [2021]
    Nyckelord :Lattice structure; AM Additive Manufacturing ; topology optimization; lattice optimization; NVH noise; vibration and harshness ; mechanical performance; lightweight; driveline; natural frequency; Gitterstruktur; AM additiv tillverkning ; topologioptimering; optimering av gitter; NVH buller; vibrationer och obehag ; mekanisk prestanda; lättvikt; drivlina; egenfrekvens;

    Sammanfattning : Lattice structures have received a lot of attention as cellular materials in recent years because of their outstanding properties, such as high strength-to-weight ratio, heat transfer, energy absorption, and capability of improving noise, vibration and harshness (NVH) behavior. This type of structure received a boost from additive manufacturing (AM) technology, which can fabricate geometries in practically any shape. LÄS MER

  4. 4. Hyra eller köpa rörläggarutrustning?

    M1-uppsats, KTH/Byggteknik och design

    Författare :Felix Forsgårdh; Karl Dahlin; [2019]
    Nyckelord :Rental machines; renting; renting versus buying; cost comparison; construction equipment.; Maskinuthyrning; hyra; hyra kontra köpa; kostnadsjämförelse; byggutrustning;

    Sammanfattning : This report will try to give clarity in when and if it is most advantageous for a specific pipelaying entrepreneur to invest in buying pipelaying-equipment or renting it to their pipelaying-projects. The purpose of the report is also to give the reader a good perception of both alternatives as it could be a useful tool in future procurements. LÄS MER

  5. 5. Implementing Innovation Partnerships : Influencing factors and their consequences

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)
