According to the general expression form of mechanical detail strength design, this paper put forward the concept of calculating the wear coefficient K_c and experimental wear coefficient K_t, and used K_c≥K_t as the expression form of Archard wear design calculation.
This paper presents the features of the loading handler, the negative pressure loading principle and method, designing calculation of the loading vacuum system, angle accuracy of the 90°indexing, and worm gears for θ and Z movements of the handler.
To make separately use of Visual Basic 6.0,Visual FoxPro 6.0 and Visual LISP develops mechanical design computation,mechanical engineering database management and mechanical engineering drawing autodrft application programming modules.
With the rapid development of CSCW, CAD has been the tool for "human-human interaction" to support the group communication and collaboration as well as for design computation, intelligence reasoning and graphics manipulation.
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.
