Overview

Human Response To Vibration

The way in which we respond to vibration from tools, vehicles and machines affects the quality of our lives, and ultimately our health. The detrimental effect of vibration of the human body has been the subject of considerable research. The understanding of this subject has now advanced the knowledge of acceptable frequency limits for vibration exposure. The weighting filters for whole-body vibration (ISO8041), affecting vibrational and ride comfort, and those for the exposure to hand-arm vibration (ISO5349) are included in the DATS Human Biodynamics package. Dose values can be calculated to ensure the acceptability of the product in an environment where the customer is ever more aware of comfort requirements, and the dangers of exposure to environmental effects.

Vehicle Crash Analysis

Also included are functions to analyze vehicle crash data with special emphasis on data from dummies. Analyses include the Head Injury Criteria, FIR100 filtering and CFC filters. All the modules comply with the relevant SAEJ211 and NHTSA requirements.

S.E.A.T. Analysis

The suite also includes s necessary for S.E.A.T. compliance testing.

Related Case Studies

  • Are You Sitting Comfortably? – Case Study

    A Prosig P8000 measures vibrations at defined points on seats designed for commercial / industrial / agricultural vehicles. The seats are tested on a 3-axis shaker rig. The DATS Human Response software is then used to check that the seat complies with the relevant standard.

  • Helmet Compliance – Case Study

    A weight is dropped on to a motorcycle helmet mounted on a dummy head. The acceleration of the weight and helmet is measured. The DATS Biomechanics software is used to check if the test has met the required profile and to verify whether the helmet meets the necessary standards.
