消防车质心位置的测试方法与研究

在分析国内外汽车质心位置的测试方法的基础上，介绍了采用“重量反应法”测定质心位置的试验方法，并对测试中的主要影响因素进行了理论分析和试验研究。结果表明，采用“重量反应法”测定消防车质心位置是一种可行的有效方法。在测试过程中，适当增大吊起角度，减少后轴轴重增量的测试误差是提高消防车质心位置测试精度的关键所在。

Study of the barycenter measurement of fire vehicle

Based on the analysis of domestic and overseas methods for vehicle barycenter measurement,introduces the experimental details of weight feedback method. Theoretically analysis and experimental study were also conducted. It is concluded that the weight feedback method is a feasible and effective way to measure the barycenter of a fire vehicle. In the experimental procedure, the key point for enhancing the meter accuracy should be to enlarge the hanging angle and to reduce the meter error of weight difference of back axis.
