本文根据汽车侧翻时，其高侧一端车轮支承平面法向力（下称高侧法向力）为零这一原理，提出了不用车轮负荷计，不通过观察高侧端车轮刚脱离试验平台台面，而直接利用装置上质量传感器的读数和相关的几何参数来测量汽车最大侧翻稳定角的方法。经试验验证，该方法稳定可靠，试验安全，不仅能测出汽车的最大侧翻稳定角，同时可以测出高侧法向力与侧翻角的关系曲线。 Based on the principle that the normal force of the wheel supporting plane at one end of the high side of the vehicle is zero when the vehicle is turning over, a wheel load meter is proposed without observing whether the wheel on the high side just leave the test platform Mesa, and direct use of the device on the mass sensor readings and related geometric parameters to measure the maximum rollover stability of the car approach. The experimental results show that the method is stable and reliable, and safe to test. It not only can measure the maximum rollover stability angle of the car, but also can measure the relationship between the normal force and the rollover angle.
