Using VB 6.0 and CATIA software, this paper illustrates a method to generate the parameters and three dimensional shapes of the hydraulic torque converter blade automatically, in order to cut the development cycle. Finally, as an example of this methodology, a particular parametric design of a hydraulic torque converter blade is presented to verify the validity of the method by establishing a VB 6.0 program, which can generate the blade parameters and the three dimensional shape of the specific hydraulic torque converter blade.
In aircraft flight control law design, the first key is to establish actual aircraft mathematical model, then according to the model of dynamic output information, analysis control law design is appropriate. But in the movement the aircraft is a complex dynamics system, modeling is very complex. This paper firstly carry out comprehensive feasibility analysis, on a plane modeling consideration simplified, secondly, in actual applications verified using the perturbation method of nonlinear equation linearization, establish the plane mathematics model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
