Slings for lifting loads in EQ1030 truck paint line were designed and calculated based on safe factor and fuzzy reliable method. The results show that fuzzy reliability of the cliver is satisfied the actual requirements.
This paper describes CAD system for the refrigerator car series, which is designed and calculated with Quick BASIC. On the basis of Auto CAD, it will be used to plot all the engineering drawings.
According to the contrasting analytic results between plane and spacial calculation, it is found that the design resist is seriously insufficient if the bevel rigid frame arch bridge is designed and calculated as a simplified plane structure.
The wellhead flanges of oil field are designed and calculated under C#. NET envirenment,second development are given to Auto CAD,method of paramenterize drawing wellhead flanges of oilfield are carried out.
Auording to the information,such as stress,strain and displacement,which is obtained in construction site,the author makes the reverse inference to determine the original stress and the peculiarity parameter of stratum. Based on this,he designs,calculates and examines tunnel and underground structure,which provides convenience and basis for deciding supporting form of stones around them,reasonable supporting time and reasonable structural design.
Finally,as an example,the real calculations for the EQ—140 truck and YK89C10 bus have been made to provide the model basis and modern design approach to vehicle transmission parameters.

The Loading effects of the box type microwave applicator has been stutied.An general analysis is made first with regard to an arbitrary load, followed by calculations concerning two concrete cases,and formulae for the frequency spectra of the loading are obtained. The loading effects of box type microwave applicator are mainly:1, The shift of the resonant frequency;2,The degeneracy splitting;3,The redaction of quality factor;4,The variation of input impedance.These loading effects lead to remarkable changes...
This paper is compiled in detail on the basis of production practice and teaching experiences together with other related informations, and provides one of the references for the technics of the design of the gas-tream drying process.Instead of complicated calculation, heat-transfer method is used in the calculation of design. So that the treatment of data is appropriate, the physical concept is distinct, and the procedure of design is clear. Physical tables in different systems ( Engineering and Internatio...
This paper deals with the device for the uniform distribution of gases-a key part in the design of the ammonia convertor (Topsue's patent) which belonging the imported ammonia plant with a yearly production capacity, of 300,000 tons. An analysis from the point of fluid mechanics have been carried out and according to the flow of gases in preforated gas dividing and collecting pipes, design calculations based on the monentum equilibrium equation have been suggested. Derivations in accordance with the momentu...
