Embodiment Construction

[0035] Hereinafter, construction machines according to embodiments of the present invention will be described with reference to the drawings. The following embodiments are merely specific examples of the present invention, and do not limit the technical scope of the present invention.

[0036] figure 1 It is a side view showing an example of the construction machine according to the embodiment.

[0037] Such as figure 1 As shown, the construction machine 100 includes: a lower traveling body 10; an upper revolving body 20 installed in a structure capable of turning relative to the lower traveling body 10; structure is installed. The working device 30 includes a plurality of driven members (boom 31 , arm 32 , and bucket 33 ) that each swing vertically. A plurality of driven members are connected to each other. The base end of the boom 31 of the work implement 30 is supported at the front of the upper revolving structure 20 .

Abstract

A construction machine (100) that comprises: a lower travel body (10); an upper turning body (20) that is attached to the lower travel body (10) by means of a structure that can turn; a work device (30) that includes a plurality of attachments (31, 32, 33) and is attached to the upper turning body (20) by means of a structure that can swing up and down; a motion state acquisition part (71) that acquires a motion state quantity for the composite center of gravity of the plurality of attachments (31, 32, 33); an equivalent system generation part (72) that generates, as an equivalent system thatequivalently expresses the actions of the work device (30), a transmission function for which a drive force that moves the work machine (30) is the input and the motion state quantity is the output; and a parameter estimation part (73) that estimates, as operation skill evaluation values, a system attenuation coefficient and a natural angular frequency for the transmission function.

Description

technical field [0001] The present invention relates to a technique for evaluating the operational skill of an operator who operates a construction machine. Background technique [0002] In the recent construction industry, the amount of investment in construction has decreased and the working population of young people has declined significantly, leading to an aging population. On the other hand, in such a social environment, there is a tendency to realize a promising construction site where wages are high and vacations can be taken, and to increase productivity by creating an attractive construction site. Therefore, it is required to balance the originally contradictory increase in productivity and the creation of an attractive construction site. In various industries including the construction industry, "i-Construction (intelligent construction)" is being promoted under the national leadership as a measure to improve productivity and create attractive sites. In this "i-...
