lift hoist performance is affected by many factors
lift hoist working conditions in complex large-scale hoist equipment , the dynamic performance is affected by many factors, the motion parameters and the load can not use a simple mathematical model describes. More than ever the static design of the main limitations greatly. At home and abroad in recent years, lift hoist design used in the design of new dynamic simulation method, using a computer in a variety of institutional and structural conditions for movement under load condition and with time change process simulation, simulation output parameters and obtain The results, in order to estimate the actual operation and infer various data.
Ergonomics of the lift hoist and the operating environment to study the system as a whole, creating a human interaction with the lift hoist best condition. Ergonomics in the application of lift hoist is mainly reflected in the design of the cab, including the driver's cab reasonable arrangement to reduce driver fatigue and improve work efficiency of the measures to strengthen environmental protection, reduce dust and air pollution, reducing cab vibration and noise.
With the lift hoist speed and larger, the need to further carry out the lift hoist load variation, the dynamic characteristics and fatigue properties of. Further work on lift hoist machine and parts reliability test research, providing lift hoist new design methods and data. Limit state design, optimization design, reliability design, finite element method, modular design, reverse engineering design, fatigue design and robust design will be more depth and comprehensive applied.
