Force Analysis of Chain Wheel and Plunger of Chain Shotcrete Machines

综述了链式喷浆机的工作原理,分析了该链式喷浆机的受力情况,通过ANSYS软件分析了活塞在缸筒中的预紧力,求得活塞与缸筒内壁的摩擦力,了解摩擦力是链式喷浆机受力的关键。通过分析链式喷浆机各部分的受力情况,了解了主动链轮的转矩,并用ANSYS分析了主动链轮的受力情况,提出优化方案,为以后链式喷浆机的设计提供了理论基础。

The working theory of chain shotcrete machines are introduced. And the force situation of the chain shotcrete is analyzed. We can know that the force of the friction is the key of the shotcrete machines＇ force, by the ANSYS analysis of the plungers＇ preload in cyclinder barrels. The torque of the driving chain wheel was acquired by analyzing every part of the machine. And finally, we analyze the force of the driving wheel, and raise the optimize project, which can be the theory of the following design of chain shotcrete machine.
