【正文】 g the design circle, by using the method of modeling, simulation first and then builds the physical prototype. Therefore, the virtual design is the developing trends of mechanical design. In mechanical system design, the application of virtual prototype is used to design mine hoist, not only speeded up the design process, also simulated a variety of conditions to the virtual prototype to discover design faults, to improve the design, to improve mine hoist performance. Mine hoist mechanical system is posed of spindle, roller, reducer, motor, brakes and other ponents. In its design, virtual design software PRO / E is applied to establish hoist prototype, application of simulation software ADAMS is used to simulate and optimize the design. Specific process shown in Figure 1: Figure 1. Mechanical system design C. Control system design Mine hoist control system includes start, run, brake, etc., the requirements in control system are: In normal hoist operation, participation in hoist speed control, brake the hoist when reaching the destination, known as the service braking。 print a test report. Figure 3. Diagram of test system The monitoring system has characteristics such as pact, light weight, high precision, testing convenient and flexible, featurerich software etc.. the system can not only display automatically test results, but also finish multiple functions, for example , data transmission, analysis, processing, storage and report printing. The system is high precision, can easily monitor the hoist operation state, to ensure the reliability of hoist operation. Ⅳ . CONCLUSIONS In this paper, used virtual design software to design the hoist mechanical system, PLC to design control system, applied virtual instrument softwareLABVIEW to design monitor system. Therefore, the mine hoist designed has good mechanical properties and safe operation, monitoring easy. REFERENCES [1] Weng qishu.
