  1. 1. Squeak and Rattle Prediction for Robust Product Development

    Författare :Mohsen Bayani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; simulation; product development; squeak and rattle; sound quality;

    Sammanfattning : Squeak and rattle are nonstationary, irregular and impulsive sounds that happen inside the car cabin. For decades, customer complaints about squeak and rattle have been, and still are, among the top quality issues in the automotive industry. LÄS MER

  4. 3. Increased precision in variation simulation by considering effects from temperature and heat

    Författare :Samuel C Lorin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat; robust design; temperature; Varition simulation; welding simulation;

    Sammanfattning : Every manufactured product deviates from the intended product. In a production series a number of noise sources will influence the product resulting in geometric variation. This variation leads to functional and aesthetical variation of the product. LÄS MER

  5. 4. Advanced measurement and modelling methods for noise source analysis

    Författare :Matti Rantatalo; Mats Åbom; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : In daily life sound is a vital dimension for the perception of the world around us but can in some cases be considered as annoying, irritating, or even harmful. In these cases the sound is labelled as noise and can be addressed in two ways, either by insulating the noise problem from the receiver (person) or by altering the source. LÄS MER

  7. 5. Dynamic response reconstruction using passive components

    Författare :Anders Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; substructuring; controllability; experimental methods; model calibration; passive control; response reconstruction; model updating; drive signal identification; Time Waveform Replication;

    Sammanfattning : In many testing applications within the field of structural dynamics, such as noise and vibration harshness, rattle and squeak, or durability testing in the automotive and truck industries, large hydraulic or electromagnetic actuators are used to excite the tested structure. Such actuators are mounted in the laboratory in a fixed configuration referred to here as a test rig. LÄS MER
