T460型汽车安全带紧急锁止性能试验台的研制

Development of Model T460 Emergency Locking Property Testing Bench for Moter Vehicle Safety Belts

为快速检验和评价汽车安全带的紧急锁止性能、研制了T460型汽车安全带紧急锁止性能试验台。介绍了该试验台的主要结构设计及工作原理。该试验台采用了微型计算机控制系统、气浮导轨机构以及气动和电动相结合的自动化技术，使得试验台具有自动测试，数据自动采集、存储、处理和曲线自动绘制及打印等多项功能。

Basic object of developing the model T460 emergency locking property testing bench for motor vehicle safety belts is finding out how to check and assess the emergency locking property of a safety belt instantly. The paper presents principal constructional design and working principle of the testing bench. Microcomputer control system,airfloating rail rnechanism and pneu-matic and electric combined automatic technology are adopted by the bench,which make the bench to possess multiple functions,such as automatic testing,automatic data acquisition,store,process-ing,automatic curve plotting and printing,etc.
