Freight cableway load saddle-passing impact power calculation method and system

Abstract

The invention provides a freight cableway load saddle passing impact power calculation method. The method comprises the steps of acquiring parameters of freight cableway bearing cable nodes and load nodes;substituting the obtained parameters of the cargo cableway bearing cable node and the load node into a pre-established motion equation of the bearing cable node and the load node; adding a time step according to the set time increment step length, solving the node motion equation, calculating the acting resultant force of the bearing cable node and the load node of the next time step until the preset time period is ended, and obtaining the acting resultant force of the bearing cable node and the load node of each time step; And taking the maximum value in the obtained action resultant force of the cable carrying nodes and the load nodes in all the time steps as a reference value for designing the freight cableway. According to the technical scheme provided by the invention, the load of the freight cableway under the action of load impact and the stress condition of the bearing cable part can be calculated, complex calculation is avoided, the calculation precision and efficiency are improved, and a more accurate calculation result is provided for cableway design and part selection.

Description

technical field [0001] The invention relates to the field of numerical calculation methods in structural design and analysis of a freight cableway, in particular to a calculation method and system for impact dynamics of a freight cableway load passing through a saddle. Background technique [0002] The overhead freight cableway has the advantages of easy selection of routes, excellent transportation performance, strong applicability, high work efficiency, and little influence from weather and external environment. It is widely used in forestry, construction, mine hydrology, tourism and other industries. The advantages of cableway, such as economy, energy saving, high efficiency and slight impact on the environment, are beyond the reach of other means of transportation. [0003] Freight ropeways mainly include working cables, including bearing cables and traction cables, brackets, running trolleys, tractors and other components. The load-bearing cable in the working cable is...

AI Technical Summary

Problems solved by technology

However, due to the lack of research on the impact velocity of the saddle under load and the change of the load-bearing and traction cables under impact, there is still no effective calculation method for the impact dynamics of the saddle under load. It is impossible to consider the dynamic impact of the impact of the load passing through the saddle on the cableway components such as the load-bearing cables, traction cables, and brackets. There is no reasonable basis for the value of the design safety factor, and it is easy to cause problems such as insufficient design strength of the cableway structural components, resulting in potential safety hazards.
