designing load
3.According to the requirements of propeller aerocraft model test in wind tunnel, specifications of the driven motor is presented by aerodynamic analysis, and a short-term operated high power density three-phase induction motor is developed with reasonably designing the motor, such as electromagnetism load, heat checkout and high-efficiency heat exchanger.
4.After an introduction to the probability design method introduced in the revised specifications for derrick design, the authors offered some views, for example, designing by means of limited loading capacity, wind load being W=β_Zμ_Sμ_Z W_0, calculating the total stability according-to "Prac tical Calculation Methods" , establishing reasonable propability models and out-of-service standards.
6.This paper introduces the designing and calculating process of the compartment beam structure that was employed in the meeting room on the sixth floor of an office building.Through this project,it states the different load-bearing performances and the different building economy of the different beam-column joint layouts in the compartment beam.
8.Based on actual data, emphasizing particularly on the course of consolidation and deformation of preloading method combing vacuum with stack-load, the paper illustrates the mechanism of deformation of pre loading method combing vacuum with stack-load from consolidation and final effect, and calculates final settlement by delamination summation-method and hyperbola method, presenting relative parameters used for designing and execution control.
9.Abstract: Based on the classical theory,the harmonic winding potential of the tooth harmonic brushless exciting generator have been calculated and analysed.The results tally with the data of no-load test very well.It was demonstrated the designing thread of harmonic winding is correct.
