This study seeks to take a closer look at how to create a reliable and repeatable method for comparative measurement and analysis of comfort regarding vibrations in strollers.To achieve this goal the study has been divided in three questions that focuses on established standards and previous studies, a construction of a measurement method and finally a construction of a data analysis method. To answer these questions the study uses information gathered from a literature study, conducted experiments as well as an analysis of quantitative data via descriptive statistics and thematic analysis. Furthermore, during the development of the comparative method the authors has made use of various workshops to generate ideas and evaluate the best course of action. This has allowed for rapid iteration of the method that is presented in this report.To make a comparison with previous studies possible, ISO-2631:1, ISO-102361:1 and the Swedish Work Environment Authority’s regulations regarding whole body vibration are used as a foundation for the decisions made. The final method is presented in its entirety, both regardingmeasurement and data analysis. This study also displays an example of how both methods can be used to compare strollers.Additionally, the report applies the developed method on a selection of Thules’ and their competitors’ strollers. For the purpose of anonymity, the strollers’ brand and names has beenreplaced with code names and taken pictures has been replaced by illustrations.Finally, the results of the report is analyzed and discussed to compare the decisions taken throughout the process with each other as well as with the current standards, regulations and previous studies. Moreover, a conclusion in made that the presented methodology is a fair toolfor measurement of the passengers’ comfort with regard whole body vibrations in strollersduring activity. The resulting data is directly comparable on a case-by-case basis, but caution is advised if comparisons are to be made with the guidelines provided in presented standards or the regulations regarding whole body vibration, as these are not adapted for measurementsconducted with children. |
