已经表明，在正面碰撞中耐撞的ANSI WC 79运输轮椅在后部碰撞中表现出灾难性的故障，并且可能不能提供稳定的座椅支撑，从而不能为轮椅乘员提供乘员保护。到目前为止，只有有限的雪橇试验和计算机模拟数据已被用于研究后碰撞轮椅的安全性。计算机建模可以作为一种经济和全面的工具，以获得有关轮椅的完整性和乘员安全的关键知识。本研究描述了模拟遭受后部碰撞事件的成年轮椅乘坐者的计算机模型的开发和验证。该模型是在MADYMO（TM）中开发的，并使用按照ISO/TC 173标准草案中提供的规格进行的三次类似雪橇测试的结果进行了严格验证。该模型的结果可以为轮椅和系留装置制造商提供关键的轮椅负载信息，从而为后部碰撞条件提供更安全的轮椅设计。(C)2009年IPEM。由爱思唯尔有限公司出版。保留所有权利。
It has been shown that ANSI WC79 transit wheelchairs that are crashworthy in frontal impact exhibit catastrophic failures in rear impact and may not be able to provide stable seating support and thus occupant protection for the wheelchair occupant. Thus far only limited sled test and computer simulation data have been available to study rear impact wheelchair safety. Computer modeling can be used as an economic and comprehensive tool to gain critical knowledge regarding wheelchair integrity and occupant safety. This study describes the development and validation of a computer model simulating an adult wheelchair-seated occupant subjected to a rear impact event. The model was developed in MADYMO (TM) and validated rigorously using the results of three similar sled tests conducted to specifications provided in the draft ISO/TC 173 standard. Outcomes from the model can provide critical wheelchair loading information to wheelchair and tiedown manufacturers, resulting in safer wheelchair designs for rear impact conditions. (C) 2009 IPEM.
