The mean duration of saccades when working on a 23% slope was 5% shorter compared to work under a 9% gradient. Similarly, fixation duration increased with slope gradient. The number of fixations during the performance of all tasks increased with the increasing slope gradient. The duration, frequency and trajectory of eye movements were used to determine the harvester operatorâs mental workload, on the assumption that worsening work conditions would be reflected by increased eyeball activity. Measurements of eye activity were obtained from a representative harvester operator working in corridors with the following mean inclinations: 9%, 23% and 47%. Within such a context, the aim of this study was to gauge aggravations of mental workload derived from increasing slope gradient. As these machines are being used under increasingly difficult terrain conditions, further knowledge is required on the expected aggravation of operatorsâ mental workload, so that suitable work/rest schedules can be developed. The use of modern multi-functional forestry machines has already been associated with central nervous system fatigue induced by high mental workload. It significantly increases reliability of hydraulic drive elements and efficiency of manipulator-type machines in forestry complex. The aim (reduction of dynamic loads) is achieved by optimizing the configuration of the boom lift cylinders and the parameters of new damper. The minimum of maximum values of the working fluid pressure is achieved when the damper throttle channel diameters are in the range of 4.0–4.5 mm. Connecting a new damper reduces the maximum pressure in the piston cavity of the hydraulic cylinder by 47%.
It takes into account the forces of inertia and compliance of hydraulic drive. The optimal position of the hydraulic cylinder, in which the fluid pressure is reduced from 12.4 MPa to 11.3 MPa, has been found.

A mathematical model of the working process of the boom lifting mechanism of serial hydraulic manipulator LV-184A has been solved. ahahaha.The article is devoted to the reduction of dynamic loads on hydraulic drive by optimization of hydraulic cylinder for boom lifting and parameters of new damping device. and pretty much if you live in mount druitt. everyone lives in housing commission, and if you dont your house is probably being tagged as you read this. everyone buys 2 dollars of devon with their shopping. fobs get around in taragos and mini buses. everyone knows that the aboriginals use their abstudy to by nike stuff. you know that putting black electrical tape on the bottom of the 'I' on your number plate will then make it an 'L' is the most genius way to steal petrol. if you live in mounty county you will know all about the tregear brawls, you will know that its 50km through whalan reserve, you dont eat kfc from emerton, you dont need money to go late night shopping because you just steal what you want, you know where the cops sit, you know that you never drive in the left hand lane down luxford road because cars always park there, you know that if you go to chifley college your parents dont care about your education, if you go to st agnes your either asian or rich. you know your cool if you wear your nautica hat and nike 'TNs'. when the fireworks are let off night, this means the drugs are in. mounty county is also known as mount druitt, mount druggit, mon drue (for the upper class people) and mount do-it. it is a place where aboriginals, indians, and fobs make the rules and by god you had better play by them, children as young as 12 will roll you, and if you arent centrelink before 7am you wont get in. A place in western sydney, nsw, between penrith and blacktown.
