The Analysis Of Dynamic Characteristics By The First Transport Of Roadheader

In accordance with the complex boring machine operating mode analysis of the firsttransport to the vertical chain board vibration characteristics and appropriate simplification,derived from the vertical vibration basic equations, to consider the start, brake anomalies, such asthe side of the different operating mode and initial conditions. Construction of vibration equationof standard forms, resulting in resolving the specific circumstances.Mechanical vibration of the first transport plane finite element model construction method,analysis of the impact factors of the scraper over the mechanics of materials; derived stableoperation of the scraper to maintain distance between the material and the thrust formula; studiedin the no-load side material formed the thrust bolt and when the scraper conveyor runningresistance, To run the path of least resistance for the distance objective optimization scraper;chute unit cell derived frictional resistance formula and the chain sprocket and the pressure angleof the calculation formula; in considering the link between the case of elastic contact problem,the flexibility of the chain extension is derived length, stiffness and tension in the relationship.The dynamic simulation model of the construction method, we construct a characteristicthat describes the shape function of transport lines, to achieve the automatic modeling of thedynamic simulation; on the conveyor start and braking, the card chain, broken chain, sprocketlimited The impact of fluctuations in the chain teeth (polygon effect), the chain pitch error andother numerical simulations carried out under different conditions, the simulation result of avariety of conditions of different factors on the impact of dynamic load.
