The Application Of Technique Of Three-Dimensional Parameterized Cad In Terminal Gearinc Of Bulldozer

This text eventually spread dynamic three-dimensional parameterized the design of CAD to make a series to the bulldozer research, and to domestic and international in common use three soft wares of Three- dimensional and soft wares development the tool made the introduction.The main research work of the thesis includes following few aspects:(1)Turn the system of CAD to the three-dimensional parameterized that spread to move eventuallies study from the theories it can carry out sex, put forward an analytical new way of thinking that front handle- the limited dollar analyzed the model of parameter turn, set up the model and parameters that parameter turn to turn excellent to turn the model, is hereafter designed other parameters to turn the system of CAD to lay the foundation.(2)At to spread to move three parameters of three -dimen sional to turn the foundation of theories research that system of CAD carry on eventually up, with the TY320 series bulldozer spreads to move eventually for carry the body, take MDT6. 0 as the terrace to carry on the concrete realization.(3)At eventually spread to move to carry on the foundation of the theories research to the series up, develop eventually spread the dynamic calculator assistance design software, for eventually sp- read the dynamic parameter to turn, the mold piece turned the design to beat to descend the foundation, for the normal regulations keep the wheel gear of excellent turn the design, the calculation and school checked etc. to provide the beneficial reference.
