A 15 t steel ingot, in which shrinkage and porosity were often found during production, was analyzed by using of casting simulation software. Position and size of the shrinkage and porosity were predicted, which agreed with the actual dissection experiment very well. On the basis of simulation results, a series of mold schemes were designed and new mold was fabricated based on the better simulation result. The new mold performed well in production.

The measurement accuracy of a tank turret rotation angle relative to the chassis absolutely determines the accuracy and stability of the aiming system and the inertial navigation system. A loaded turret of most battle tanks has a low rotation angle measurement accuracy relative to the chassis, there is a need to solve the problem of steering the tank body only. This paper proposes a high-precision testing system which works on the multi-channel dynamic condition based on Fuzzy set theory and data fusion of the tank turret rotation angle. We introduce the working principle and process first, then make calibration and error analysis on the device. Results of the joint commissioning on the battle tank proved the testing system has met the actual specification. © 2016, UK Simulation Society. All rights reserved.

The application of inteCAST software in ductile iron housing was analyzed. With the help of CAE software, four kinds of processing design for the ductile iron housing were visualized to predict and analyze possible shrinkage holes (porosities). The results show that, through optimizing process, shrinkage porosities (holes) in the ductile iron housing can be eliminated effectively.
