“…According to the test data in a typical mining conditions, total energy for 0.043kWh of excavator's single cycle recovery can be calculated by formula (1) ~ (2). With the condition that the mining cycle length is 12s, 2000 work hours can be done, engine fuel consumption rate is 240g/kWh, 1kg standard coal combustion produces 2.93 × 107J calories, 20 ton excavator saving is about 6192kg, the single direct economic benefit is nearly 60000 yuan per year, 11.6 tons CO2 can be reduced to produce.…”

In order to achieve the purposes of better energy saving and lower fuel consumption under the condition in which load changes frequently and fluctuates dramatically, the energy-saving control strategy of power system is put forward in a hydraulic surface drilling rig. The structure of power system and working conditions of hydraulic surface drilling rigs are described. The mathematical models of the external characteristic for engine, variable pump, and air screw compressor in hydraulic surface drilling rig are presented in detail. Then the control strategy of power system and the fuzzy PID control algorithm to implement this strategy are proposed to control the engine speed in various working states. The simulation analysis and experimental investigation are carried out to study the fuel consumption in the typical operating conditions by using energy-saving control strategy. Results show that the energy-saving control strategy can reduce fuel consumption for the hydraulic surface drilling rig while ensuring that the system performance is not sacrificed.

“…When the ice and snow on the road are in the different state, the adhesion coefficient of pavement has great difference [3]. In recent years, the studies of tyre's adhesion characteristics on ice and snow pavement are the research focus in the field of tyre science and vehicle control science in Japan, the United States and Western Europe countries [4]. The adhesion coefficients of ice and snow pavement in different forms are measured in Japan and the range of adhesion coefficients is given and shown in Table 1 [5].…”

The number of traffic accidents caused by ice and snow is generally three to four times higher than that in normal condition. In order to improve safety level when driving on ice and snow pavement, adhesion coefficient is a vital parameter need to be analyzed. The relations between adhesion coefficient and temperature, relative humidity, snow’s thickness, snow’s compactness were studied. And their relation models were established. These models may provide the basis for the road administration department to conduct traffic control decision-making according to the weather condition and the state of ice and snow.
