车载式拖拉机座椅舒适性测试系统的研究

Measurement System for Ride Comfort of Tractor Seats

应用美国模拟器件公司的 ADXL 10 5微型力平衡式加速度传感器、美国 Cygnal公司 F32 0型单片机组成车载式拖拉机座椅舒适性测试系统 ,系统易标定、成本低、供电方式简单。试验结果表明 ,在其他条件相同时 ,拖拉机座椅固有频率只要避开人体敏感的频率范围 ,座椅的舒适性就能得到明显的改善。

This paper presents a new test system for ride comfort of tractor seats by using ADXL105 and C8051F320. The whole system has the features of low costs and easy for use. The field tests show that the riding comfort of seats will be greatly improved if the resonant frequency of seat is not within the range of human sense when all the other conditions are unchanged.
