The paper describes a mathematical model for wheeled vehicle with automatic transmission of «torque converter - coupling - gearbox» type. In order to compare this type of transmission and mechanical one with same number of gears and ratios, optimal characteristics of torque converter for considered vehicle are selected. The paper presents the results of simulation of wheeled vehicle moving for both variants of gearbox in conditions involving variable resistance and moving velocity assigned by driver. Efficiency of hydromechanical transmission use is estimated.
The paper deals with the problem of excessive workplace noise levels of the production facilities, the existing levels at workplaces of the typical production facilities are assessed on the basis of the statistical data obtained as a result of in situ measurements. Typical technical measures which do not require technical re-equipment of the production facilities and enable reducing noise levels are considered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
