Abstract

Abstract: Based on the analysis of the stability of concrete truck mixer with no load or full load , the theoretical calculation method of safety speed fO,r vehicle turning was presented. The block diagram of real-time computing systems of safety speed was established and the cOlTesponding front-panel diagram of the virtual instrument was also designed , according to the environment of the software of Lab VIEW and its calculation method. In the case of corresponding sensor , the virtual instrument displayed the safety speed at real time and had early warning function for mixing truck when turning. The driver can get a speed reference in time by this instrument. It effectively improves the turning security

Key words: safety speed, Lab VIEW, real-time, virtual instrument, early warning

摘要： 在阐述棍凝土搅拌运输车空载、满载时侧翻稳定性分析的基础上，总结出转弯时安全车速的理论计算方法;基于LabVIEW 软件开发环境下，依据其计算方法，搭建出安全车速实时计算系统的程序框图及设计出相应的虚拟仪器前面板阁，当搅拌运输车转弯行驶时，在配有相应传感器的情况下，该虚拟仪器具有实时显示安全车速和预警功能，给驾驶员一个及时的速度参考，从而有效地提高其转弯安全性。
