According to the results of explosion experiment and nonlinear finite element analysis of the head of 914mm dryer, the feasibility of the theory of limit load of cast iron applying to the design of heads of dryers is studied and the designing calculation principle for heads of dryers is established.
Parametrization of design process is realized by adopting object-oriented method, the main function of this system is to manage the designing parameters submitted, design, computation, analysis and select of mechanism are finished, simultaneously, the result of design is autosaved and document of design is exported.
In the article the locus that axle center of the roller relative moved on the cam was considered center and bridge of inferce and calculation,the mathematical description of plane roller cam was divided into two interrelation parts,so the trains of thought for positive and negative calculation were clear,easy to carry out the design computation of the complex cam curves of plane roller cam with computer.
The results show that the calculated thermal conductivity of rock is reliable and useful for the design and calculation of geothermal development in the Bj?rk? area.
Based on the experience in design and calculation of operation regimes, specific features and general concepts of the relay protection for magnetization-controlled shunt reactors for voltage of 110-500 kV are described.
A simple equation is suggested that can be used in the practice of the design and calculation of filters.
The paper reflects the common design and calculation methods and shows their limitations in regard to the calculation of hydrostatic bearings at high velocities.
This paper presents the design and calculation of a press fit joint between a fibre reinforced plastic tube and an aluminium cylinder.
