By using solidworks software,The models of AOD converter shell and molten steel for obtaining the areal coordinates are created to make refined calculation about the tilting moments of the new or old converters.

The application of Auto CAD to the calculation for tilting moment of melting equipments makes the calculation process more simple, convenient and precise.

The paper described a method of converter modeling, tilting moment analysis and dynamic simulation.

The paper presents a discussion about the calculating model of converter tilting torque in detail, and gives a simple but practical calculating diagram , a research upon the relationship between the liquid volume and its top level line inside the converter and puts forward a method for determing the iterative ste

Many factors affect the calculation of converter tilting torque,especially furnace structure.

Tilting torque of torpedo-like tank is an important parameter in the design of tilting mechanism, peoples used to depend on hand computation in calculating tilting torque of torpedo-like tank with low computing speed and computational accuracy.

Presents the inertia overturn moment of wrap that exists in the first balance design of scroll air compressor at the same time,analyzes the influences of the inertia ouerturn moment of wrap on the overturn moment of orbiting scroll and its operation stability,and gives computational formula of the acting angle of the inertia overturn moment.

Analysis of miner's overturning moment under different bottom angle;

Geometrical model of scroll compression mechanism without overturning moment;

A method for calculating overturning moment of multi-storey block structures under earthquake;

Under the condition that all indices satisfied the code,it is suggested that the proportion of bottom overturning moment for short-pier shear wall shouldn t exceed 70% of the total for small tall building(less than 45m of total height) and it should be less than 50% of it for middle and tall building(mo.
