The authors have been conducting development of an autonomous loading system by wheel loader. As a part of the development, a detection method of location of the dump truck will be described in this paper. In the process of loading to the truck in the operation, the loader approaches to the dump truck in very close distance. The function for collision avoidance between the loader and the truck ...
One of the challenging problems for surface mining operation optimization is choosing the optimal truck and loader fleet. This problem is the Equipment Selection Problem (ESP). In this paper, we describe the ESP in the context of surface mining. We discuss related problems and applications. Within the scope of both the ESP and related problems, we outline modeling and solution approaches. Using...
Operation payload management investigated the impact of two weighing technologies (truck and loader installed scales), operated by hired drivers owner-operators on route types; gazetted (classified for increased GVW limits) non- (standard limits public roads). On non-gazetted roads approaches proved equally effective but when used together appeared to be less effective, while owner operators ha...
Three-dimensional simulations of diesel particulate matter (DPM) distribution inside a single straight entry for the Load-Haul-Dump loader (LHD)-truck loading and truck hauling operations were conducted by using ANSYS FLUENT computational fluid dynamics software. The loading operation was performed for a fixed period of 3 min. The dynamic mesh technique in FLUENT was used to study the impact of...
Traditionally, the earthmoving operations have been developed based on the minimum cost per production criterion. Nowadays, due to the negative impacts of the emissions on the environment, there is an increasing public awareness to reduce the emissions from the earthmoving operations. Different management strategies can be employed to reduce emissions, amongst other things, which can also resul...
Operators of construction vehicles are constantly exposed to whole body vibration, which can lead to musculoskeletal disorders. The aim of present study was to evaluate the impact of exposure to whole body vibration in operators and its relation to musculoskeletal disorders. This study is a descriptive-analytical study. Using easy sampling, 89 operators from 6 types of heavy vehicles (Bulldoze...
The accurate prediction of vehicle speed is crucial for the energy management vehicles. existing (VSP) methods mainly focus on road vehicles and rarely off-road In this paper, a double-layer VSP method based backpropagation neural network (BPNN) long short-term memory (LSTM) proposed. First all, considering motion characteristics vehicles, problem established relationship between variables in c...
The drivers of ten vehicles (tram, helicopter, saloon car, van, forklift, two mobile excavators, wheel loader, tractor, elevating platform truck) were studied with regard to the combined exposures of whole-body vibration and awkward posture during occupational tasks. Seven degrees of freedom (DOFs), or body angles, were recorded as a function of time by means of the CUELA measuring system (Comp...
Traditional loaders with engines present the drawbacks of high energy consumption and poor emissions performance. The usage an electric motor instead engine in loader can effectively improve efficiency emissions. is mainly used earthwork construction unstructured roads. Compared to automobile, during working process loader, load fluctuates violently, vibration serious. A large torque range oper...
Planning of forest transportation is a complex problem that requires effective and harmonious design implementation various operations including extraction, loading, hauling products. These constitute significant part the total cost producing products; therefore, developing most appropriate (minimum cost/maximum net profit) plan has increasing importance for economic aspect. Computer-aided mode...
