77-30569/315859 Analysis of deflected mode (DM) of three-disk plane of almost instantly changeable system
Engineering Education # 03, March 2012
When designing constructions it is important to control the internal forces in order to produce machines and constructions with a rational mass. Such control is possible with the help of tracking tightenings produced on the basis of almost instantly changeable systems. The article is dedicated to the analysis of deflected mode of a three-disk flat almost instantly changeable system for the purpose of its usage in tracking tightening. The change of forces which appeared in the rods was considered depending on the angle of inclination of one of the rods in the system and on the external force time variable.
77-30569/308514 Research of the influence of fastener’s form on the strength of “metal-composite” joint
Engineering Education # 02, February 2012
Practicable methods of fastening of the composite details with metal parts of designs were researched. The results of tests were presented; empirical dependence for the forecast of working efficiency of such joints was proposed. Regression and dispersion analyses of obtained test data were carried out. Future development of such joints was outlined.
