施工机械的最大生产率P_(max)是表征机型特点的数值(规格)u和物料装运位移量(运距或转角)s或φ的函数。从系统工程学的观点考虑,引入施工对象、作业条件以及环境因素等一系列修正系数multiply from i=1 to n K_i后,得到施工机械白班使用生产率Q=f(u)·f(s,φ)·multiply from i=1 to n K_i。本文提出的这一经验公式,在单斗挖掘机、推土机等土石方机械的使用上具有一定的实用意义。
The maximum production rate P_(max) of the construction machine is a function of the value (specification) u that characterizes the model and the displacement (distance or rotation angle) s or φ of the material shipment. From the point of view of system engineering, after introducing a series of correction factors multiply from i=1 to n K_i, such as construction objects, operating conditions, and environmental factors, the productivity of the daytime use of construction machinery Q=f(u)·f(s,φ )·multiply from i=1 to n K_i. The empirical formula proposed in this paper has certain practical significance in the use of earth-rock machines such as single-bucket excavators and bulldozers.
