The design of the LHD working device is a complex problem, often related to multi-variables, multi-objective, nonlinear constraint. In this paper, MDO theory is proposed with 14t wheel loader as research target and Isight is as the multidisciplinary optimization platform combined Matlab, Solid work sand Simulation. The mathematical model of working device is established based on Matlab, and sin...

Taking the Enterprise Resource Planning system of a loader enterprise as an example, this paper expounds on principle master material data coding, existing problems in standardization process and measures taken.

In this article discusses the relevance of development and creation a multipurpose single-bucket loader with transforming working body reduction branches national economy, where machines equipment dump bucket bodies are successfully operated when performing basic construction installation budget-forming works. Also, an analysis difference between adapting fundamental differences is given, since...

the single wheel tester is an experimental device used to measure wheel forces when studying the relation of soil and wheel in a soil bin or in the field. in the model under development, a special frame holding the test wheel is connected to a loading carriage by two pairs of vertical rails and four rollers to provide a floating connection. by applying a driving torque to the test wheel shaft, ...

To investigate how the buying behavior of firms work is always needed, since it is an every changing process influenced by many forces in its surroundings. Industrial firms tend to have a smaller number of customers which means that they are easier to identify than customers in consumer markets. Effective marketing strategy relies on understanding consumers and their needs. This understanding m...

Abstract The purpose of the study is to substantiate parameters deep-loader mole-drainage gun. A diagram a gun given. main working parts mole drainage tool are deep loader, knife, rope and drainer. Analytical dependences obtained for determining traction resistance Theoretical studies have established that high-quality loosening soil with minimal resistance, height digger should be 90 cm, width...

UNLABELLED An object metamodel based on a standard scientific ontology has been developed and used to generate a CORBA interface, an SQL schema and an XML representation for macromolecular structure (MMS) data. In addition to the interface and schema definitions, the metamodel was also used to generate the core elements of a CORBA reference server and a JDBC database loader. The Java source cod...

Apart from regular wheel wear such as decreasing wheel diameters and reduced flange thicknesses and heights, wheel flats (WF) and oval wheels (or OOR, Out-Of-Roundness) are the most common wheelset problems for railway vehicles. Within the FP7 Research Project “Saferail”, APT has developed an innovative wheelset monitoring system so-called “Wheel flat and Out of Roundness Monitoring (WORM) syst...
