Abstract:

Prediction and assessment of seated postures are essential for ergonomic vehicle design whereas dynamic seat interactions are essential for impact conditions. This paper presents seat models and human models for both applications. An interface has been developed to convert RAMSIS human models and postures to MADYMO. Static seat interaction analyses with RAMSIS provide estimated postures and a qualitative comfort assessment. MADYMO simulations allow analysis of required muscular joint torques as well as seat contact forces and pressures. An example is included where a realistic posture is deriv

Abstract:

Multibody models have not yet been evaluated for reconstructing head kinematics during sports impacts. Accordingly, the goal of this study was to utilise whole-body motion data from twenty upper and mid/lower trunk rugby shoulder tackles recorded in a marker-based 3D motion analysis laboratory to assess the MADYMO human body passive ellipsoid model for head kinematic reconstruction. Head linear and angular velocity during the tackle for the multibody model predictions and 3D motion laboratory measures were recorded for the ball carrier. Examined were the linear and angular velocity, as well as

Abstract:

In rail passenger seating arrangements with workstation tables, there is a risk of serious thoracic and abdominal injury. Strategies to mitigate this injury risk are being developed through a cooperative agreement between the U.S. Federal Railroad Administration and the Rail Safety and Standards Board of the United Kingdom. The approach to developing the protection strategies involves collision investigations, computer simulations of the occupant response, and full-scale testing. During the train collision in Placentia, California, on April 23, 2002, many occupants hit workstation tables. The

Abstract:

Recently, with an increase in the number of studies of the safety of both pedestrians and passengers, computer software, such as MADYMO, Pam-crash, and LS-dyna, has been providing human models for computer simulation. Although such programs have been applied to make machines beneficial for humans, studies that analyze the reconstruction of accidents or crime scenes are rare. Therefore, through computational experiments, the present study presents reconstructions of two questionable accidents. In the first case, a car fell off the road and the driver was separated from it. The accident investig

Abstract:

The risk of injuries and fatalities is severe when bus superstructure fails during rollover accidents. This study deals with two stages of analyses which are superstructure strength having rollover analysis and occupants kinematic analysis. The validation process by correlating the strain results obtained from simple box rollover and simulation process done. The inputs from validation process had been used for full-scale bus superstructure rollover. A complete bus structure was developed and simulation was done according to the United Nation Economic Commission of Europe (UNECE) regulation 66

Abstract:

This paper presents efforts made on the computational modelling, simulation, and optimization of a new type of airbag, namely a sandwiched tube-type airbag, which deploys more rapidly than the traditional airbag using less gas mass inflow and can decrease the risk of head injury of an out-of-position passenger. The airbag is modelled using the finite element method with MADYMO. A static airbag deployment test is performed to support and validate the computational modelling efforts. The considered variables for airbag optimization design are as follows: the collocation of the tether, the length

Abstract:

This paper is devoted to study of the helmets which can provide protection for the operator against head injury during an rollover accident. In the present study, the proposed procedure is demonstrated with the help of a validated madymo model of a featureless Hybrid Ⅲ headform in conjunction with a helmet model comprising an outer polypropylene shell to the inner surface of which is bonded a protective polyurethane foam padding of a given thickness, a parametric analysis has been performed in order to investigate the effect of different densities and thickness of the polyurethane foam on the

Abstract:

In the event of an impact with an automobile, pedestrians suffer multiple impacts with the bumper, hood and the windscreen. The characteristics of a vehicles front end and structural stiffness have a significant influence on the kinematics and injury risk of the pedestrians body regions, in a vehicle-to-pedestrian collision. In this present study, the injury risk of the pedestrian is investigated in an impact with a deformable vehicle front end model for the purpose of validating the developed model. A simplified vehicle front end model consisting of a multi body windscreen and a finite elemen

Abstract:

Purpose This paper aims to present the assumptions, analysis and sample results of numerical modeling and analysis of dynamic events encountered in emergency cases during deployment of parachute rescue system (PRS) and hard landing of a small gyrocopter. The optimal design requires knowledge of structural loads and structural response – the information obtained often from experiment. Numerical simulation is presented as an alternative tool for estimating these data. Design/methodology/approach Structural analyses were performed using MSC.Nastran. Multibody simulations were done using MADYMO sy
