The invention relates to the technical field of
simulation, in particular to a rectangular spline contact
kinetics simulating method based on
assembly feature information. The method comprises the following steps: first step, analyzing spline
assembly feature information; second step, establishing a perfect spline geometrical model; third step, adding the
assembly feature information; fourth step, establishing a contact
kinetics model; and fifth step, solving a simulating result. The rectangular spline contact
kinetics simulating method based on the assembly feature information has the beneficial effects that spline assembly feature information including fit tolerance and tooth profile tolerance is considered, the working state of a spline is simulated by contact kinetics, according to a simulating result, influences of the fit tolerance of the spline and the tooth profile tolerance of the spline to the dynamic characteristics of the spline can be obtained, influence of different tolerance selection to spline tooth contact forces is obtained, the simulating result conforms to a real result, the service life of the spline can be analysis under the effect of
impact load,
simulation calculation can be carried out by the
algorithm, and the design result can be close to reality.
