本文介绍了利用计算机辅助完成重型越野车转向系台架试验的原理、思路以及相关的软硬件等。在系统测试中 ,采取一种以固定时间片定时查询的方法实现系统数据的实时采集。试验表明 ,只要设置合适的时间片 ,系统便完全可以实现“实时”工作模式。 This article describes the use of computer-assisted heavy-duty off-road vehicle steering system test bench principle, ideas and related hardware and software. In the system test, take a fixed time slice timing query method to achieve real-time data collection system. Experiments show that as long as the appropriate set of time slices, the system will be able to achieve “real-time” mode of operation.
