工程车辆座椅舒适性分析与改进(中文3700字,英文2100字)
摘要
传统工程车辆侧重对工作的完成，对驾驶员的影响考虑较少。近年来，随着科学进步和人们生活水平的提高，在口常工作中，除了对工作的完成度之外，人们还对在工作中的健康和舒适性提出了更高的要求。如传统的农用机械不提供驾驶员座位，人跟着机器走是一件很耗体力的事情，随后供驾驶员乘坐的座位便出现了。起初的仅是一个刚性的座斗，对乘坐舒适性并没有很多要求。研究和事实表明，这种座斗乘坐舒适性很差，无法缓冲车辆工作过程中所产生的振动，甚至对车辆的振动起到放大，作为提高其舒适性，有关部门出台了标准来约束制造商，例如GBT 14779-1997就是又姿人体模板功能设计要求的一种约束。

THE ANALYSIS AND IMPROVEMENT OF THE
ENGINEERING VEHICLE SEAT
ABSTRACT
Traditional Engineering Vehicles were emphasized on the completion of the task while pay less attentions on the driver. Recently, with the development of science and technology,during the routine work, people are increasingly laying stress on the health and comfort. Take the traditional agricultural machine for example, it has no seat for the tiller, people realized that one person chasing behind a machine is a tiring work. During the following engineering machines, the seat for the driver appears. However, the primary seats are rigid ones, leaving a space for the worker and paying less attention to the comfort of the driver. The research and fact show that the rigid seat hardly absorbs vibration, sometimes, it would amplify the shaking. To gain good quality of comfort of seat, some laws were implemented to supervise the seat or vehicle manufacturers to produce seat in good quality. For example, GBT 14779一1997 was issued to constraint the sitting posture of the seat. [资料来源：http://doc163.com]
