Increasing urbanization and construction & mining activities are amongst some of the primary factors fueling the demand for earth moving equipment in recent years. On the flipside, enforcement of stricter laws to check rising emission levels is limiting extensive use of such equipment. Moreover, most of the equipment used in mining, construction, farming, forestry, and other industries have a complex operating system and require extreme care in handling. Countries such as Turkey, India, Canada, and the UK present a high demand for equipment such as mini excavators, crawler, wheeled, and compact loaders. This, in turn, compels manufacturers to design earth moving equipment that are more requirement-specific and can meet client expectation. The report also observes that upcoming government infrastructural and construction projects in both developed and emerging countries are expected to create immense opportunities for earth moving equipment manufacturing companies. In addition, various PPP (Public Private Partnership) projects involving huge investments in commercial and residential constructions is expected to drive the growth of earth moving equipment market in the medium term. Public-private partnership guarantees better institutional legal framework for private investors while helping governments to progress rapidly in developing country's public welfare infrastructures.

The mixing blades of concrete mixer, is a relatively complex spatial surface, which is difficult to manufacture. The high cost of traditional mold making does not apply to new product development and experimental studies. So, this paper presents a rapid manufacture method of balde mold, which using the UG software for blade parametric design, and then sub-cutting it to calculate the section coordinates. According to the coordinates, the steel plate had been cut and welded into a mold, through which, the blades can be pressed. Because of its convenient and low-cost, the method is particularly applicable to the occasions of experimental research. © (2010) Trans Tech Publications.

A zero fuel auto-learning calibration strategy was adopted and the concept of engine segment acceleration was introduced. When the necessary condition for calibration and the rail pressure defined by the calibration were required in overrun phase, zero fuel calibration triggered small injections to a cylinder, and attempted to detect a change in the engine crankshaft segment acceleration. Then, the parameters for the injections were changed in predefine step value for the energizing time until a predefined segment acceleration change was detected between two neighborhood injections. Finally, the energizing time was saved as zero quantity calibration value of the injector in the rail pressure defined. The injection bench and the experimental vehicle test results showed that zero fuel auto-learning calibration strategy does not need to add any components, and it has higher calibration veracity and real-time characteristic.

Compared with traditional liquid and solid processing methods, semi-solid die casting process can apparently overcome shrinkage cavity and porosity defects in castings and high deformation resistance and high residual stress shortcomings in forging parts. Semi-solid die casting process with advantages such as high efficiency and low cost, will become the optimal process for high quality automobile parts. In this study, using the clamp as an example, the author introduced product structure optimization and die design for semi-solid die-casting process of aluminum alloy in a new product development. The Computer Aided Engineering technology was applied to the product structure optimization according to the stress analysis. The optimal mold structure, including cavity layout, gating system, overflow and vent systems, were confirmed based on the die design criteria for traditional die casting, combining with the characteristics of semi-solid forming and the simulation results. The semi-solid aluminum alloy clamp parts with excellent performances were finally developed successfully by means of product structure optimization, die design, parameters optimization of die casting process, and the mechanical properties test of products. The existing parts were optimized to make them more suitable for semi-solid die casting processing. In addition, a reasonable die design specially for semi solid processing was an important guarantee for a successful semi solid product applied in industry. Computer numerical simulation was applied in product structure design for semi-solid die casting, die design, die-casting process optimization and other aspects, to shorten the development cycle of new product, reduce cost and improve efficiency. © 2016 Trans Tech Publications, Switzerland.
