The Kinetic Study And Parameter Optimization Of Airborne Roofbolter

This paper takes a analysis of the cutting process of roofbolter, and calculates the largesttorque and thrust force of bolter and other parameters.It consideres those parameters as designparameters to design the bolter. At the same time, it takes our coal mine tunnel actual asbackground, takes the EBZ-160as the carrier for the bolter.The paper analysizes the bolterinstalled location, and solve link style and other important technology of bolter and header.Then,it designs a airborne roofbolter that can both drill tunnel side and top blot’s hole.In addition, this paper conductes a three-dimensional modeling of roofbolter.And thethree-dimensional modeling can be imported into the ADAMS model by the use of interfacesoftware of Mechanism/Pro.Then,it takes both Multi-rigidbody dynamics simulation andRigid-flexible coupling dynamics simulation. And it analysizes drill positioning errors of themovement of the work process, and compares the diffenrence of the use the shock absorber ornot. The hydraulic cylinder force is analyzed. And the maximum force of the hydraulic cylinderand deputy campaign is obtainde. The key parts’ strength of the airborne roofbolter is checked,and the stability of the drill pipe is checked. The contact dynamics of key components is taken.Finally, by the topology optimization method the part that requires lower accuracy is optimized.By the use of the reliability theory, the mathematical model of parameter optimization isestablished.Then, the optimization of the key components is implemented by Pro/E and AWE.And it analysizes the optimization results.
