摘要

某型干混物料运输车取力器的紧固螺栓出现频繁断裂的问题,采用试验和仿真方法对该故障进行分析。变速箱取力器通过传动轴驱动空压机,通过空气压力把物料输送到工地料仓中。测试了不同转速下传动轴上的力矩特性,发现低转速下力矩值大,并且力矩波动范围大。建立了取力器的疲劳仿真模型,施加不同转速下的力矩载荷,分析了在不同转速时取力器螺栓的疲劳寿命,发现转速越低,取力器螺栓疲劳寿命越短。研究得出,在低转速下空压机存在强交变力矩是导致取力器螺栓断裂的原因。通过干混车的定速巡航功能,让空压机转速稳定在950 r/min,解决了取力器螺栓断裂的问题。

Abstract

Experiment and simulation method are adopted to analyze the bolts fracture of the power take-off box of a certain type of dry-mixed mortar transport truck. The power take-off box gets power from the gear box and sends it to the air compressor through transport shaft, the materials are transported to the storehouse through the air pressure. The torque of transport shaft is measured at different rotation velocity. Results show that the torque value is high value and high aptitude at low rotation velocity. The analysis results of the fatigue life of bolts at the toque of different rotation velocity indicated the lower the current speed, the shorter the fatigue life of the power take-off bolt. It is concluded that air compressor working at low speed is the reason for the bolts fracture problem. The problem of the power take-off box bolt was solved by keeping the speed of air compressor at 950 r/min through the constant speed cruise function of the dry hybrid vehicle.
