砼搅拌输送车在我国生产的历史不长,许多问题还有待解决,行驶稳定性就是其中较突出的问题之一。本身重心较高且边行驶边搅拌,拌筒内拌合料流动造成重心位置的偏心振动,是使输送车行驶稳定性较之其它工程车辆差的主要原因。据司机普遍反映,开车时明显“发漂”,特别是在拐弯时须严格控制转弯速度,否则很容易发生事故。因此,研究输送车行驶稳定性,对提高商品混凝土的生产率和安全生产都有重要意义。一、重心位置变化对行驶稳定性的影响 1.输送车失稳角计算工程车辆一般用失稳角来衡量行驶稳定
The history of production of agitation and mixing trucks in China is not long, and many problems remain to be solved. Driving stability is one of the more prominent problems. The high center of gravity and stirring while driving, the eccentric vibration of the center of gravity caused by the flow of the mixing material in the mixing tube is the main reason for the poor running stability of the transportation vehicle compared to other engineering vehicles. According to the driver’s general reaction, it is obvious that when driving, “drift”, especially when turning, the speed of turning must be strictly controlled, otherwise it is very easy to accident. Therefore, it is of great significance to study the stability of transportation vehicles and to improve the productivity of concrete and safe production. First, the impact of changes in the location of the center of gravity on the stability of driving 1. The calculation of the instability angle of the transmission vehicle is generally used to measure the stability of the vehicle using the instability angle
