A bulldozer comprises a main machine frame (1). An engine (2), a machine cover and a rear exhaust gas processing device (3) are arranged on the main machine frame (1). The air inlet of the rear exhaust gas processing device (3) is connected with the air outlet of the turbine engine (2) through a pipeline. The rear exhaust gas processing device (3) is fixed on the machine cover. Vibration generated by the engine (2) in the bulldozer needs to be transmitted to the main machine frame (1) through an engine supporting frame or a shock-absorbing device, and then is transmitted to the machine cover through the main machine frame (1). The vibration transmission path is long, and the vibration damping becomes complex and the damping value is high. The vibration transmitted to an air filter (4) is very small, and the vibration of the main machine frame (1) caused by the working of a scraper knife working device is also transmitted to the rear exhaust gas processing device (3) through the main machine frame (1), the machine cover, the shock-absorbing device and the like, so that the vibration transmission path is long, and the rear exhaust gas processing device (3) is accordingly less influenced by vibration caused by working of the working device. The rear exhaust gas processing device (3) is arranged on the machine cover, so the length of an exhaust pipeline can also be shortened, the pipeline arrangement can be optimized, and the system working reliability can be improved.

In order to address the poor continuity of the three-dimensional blade morphology caused by the conventional design method that is based on the projection theorem for isoclinic angles, we present a strategy for designing the blade thickness of the hydraulic torque converter (TC) with the characteristics of the National Advisory Committee for Aeronautics (NACA) airfoil. By defining the subsection constraints of the NACA airfoil, the designed blade can meet the fluid-structure interaction requirements of the hydraulic TC, and confirm its airfoil function. In addition, based on the airfoil function and the rules for a ruled surface, we derived the blade thickness and normal thickening direction, and then obtained the blade thickness vector of the hydraulic TC, which realized the blades thickness design (called the normal thickening method, for short). Taking the blade design of the twin-turbine TC as an example, we used this method and the projective method for isoclinic angles to establish the model. By comparing the computational fluid dynamic (CFD) simulation and rack test results, we found that by using the proposed method, the design parameters of the blades could be effectively reduced. The designed drop-like blades could improve the efficiency of the hydraulic TC, and an automatic blade design can be realized. © 2016, Editorial Board of Journal of Harbin Engineering.

In order to improve Liquid fertiLizer efficiency, Liquid variable fertiLizing control system was designed with two working modes: a manual control and an automatic control mode. Taking the S3C44B0X microprocessor of ARM7 series as the core device, according to the fertiLizing amount of the current location, the system was able to combined together for the machine speed and access to data, and the fertiLizing amount from digital quantity to the flow of Liquid output was transformed. Flow Sensor was taken, a closed-loop feedback regulation to control the opening of electrical actuators was formed, adjusted valve opening to compete the variable fertiLization. The test results in the field showed that the relative error of the variable fertiLizing amount was less than 5%, When the fertiLizing amount was 245-294kg/hm2, the system can reaLize the requirements of variable fertiLizing. © 2011 IEEE.

Considering low utilization rate of sheet metal, the low nature of a complete set and the overmuch work-in-process in the workshop during the process of the structural members of engineering machinery, this paper proposes a new optimized cutting method based on group technology with the basis of present sheet metal cutting. This method adopts the principles of divide and rule, which divides the processing cutting parts into several groups by clustering and deals with them separately. The method has been applied in industrial production and achieved good results. © (2011) Trans Tech Publications.

An interpolating reproducing kernel particle method for two-dimensional (2D) scatter points is introduced. It eliminates the dependency of gridding in numerical calculations. The interpolating shape function in the interpolating reproducing kernel particle method satisfies the property of the Kronecker delta function. This method offers a mathematics basis for recognition technology and simulation analysis, which can be expressed as simultaneous differential equations in science or project problems. Mathematical examples are given to show the validity of the interpolating reproducing kernel particle method. © 2014 Chinese Physical Society and IOP Publishing Ltd.

The follow-up control of concrete pump truck is in order to solve the problem that whole boom follows the movement of boom end under the artificial traction. Focus on real-time detection of boom end azimuth change and inverse kinematic problems of redundant boom system, two-axis gravitational accelerometer is used to detect azimuthal variation of boom end, and the best motion trajectory of boom is determined by solving constrained nonlinear optimization function which takes minimum displacement distance of barycentre for the whole boom as the optimization goal. At last, relative azimuth and translation of boom end, rotation of boom are solved together to make translation and rotation of boom being synchronization. In this way to ensure whole boom follows the artificial traction in theory. In order to verify the discussion above, matlab is used to simulate several different working conditions for the follow-up control of boom. © (2013) Trans Tech Publications, Switzerland.
