Description

technical field [0001] The invention relates to the technical field of engineering cost specificity analysis, in particular to a modeling method for analyzing the efficiency reduction of high-altitude power grid engineering construction machinery. Background technique [0002] Mechanical degradation refers to the objective phenomenon that the mechanical efficiency is reduced due to the inability to perform normal quotas in complex working environments such as plateaus and high altitudes. Due to the characteristics of high terrain, thin air, and low temperature in high-altitude areas, it is easy to reduce engine power during construction, resulting in insufficient engine combustion, increased fuel consumption, and increased exhaust temperature, specific fuel consumption, and smoke. On the other hand, the machine operator's ability to operate the machine and the accuracy of the machine will decrease in high altitude areas, which will also affect the normal performance of the m...

AI Technical Summary

Problems solved by technology

Due to the characteristics of high terrain, thin air, and low temperature in high-altitude areas, the power of the engine is likely to decrease during construction, resulting in insufficient combustion of the engine, increased fuel consumption, and increased exhaust temperature, specific fuel consumption, and smoke.

On the other hand, the machine operator's ability to operate the machine and the accuracy of the machine will decrease in high altitude areas, which will also affect the normal performance of the machine's efficiency.

Therefore, in the construction of power grid projects in high-altitude areas, there are obvious mechanical degradation
