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.

Description

technical field [0001] The invention relates to the technical field of simulation, in particular to a method for simulating contact dynamics of a rectangular spline based on assembly feature information. Background technique [0002] Spline is an important form of transmission connection with high reliability and is widely used in power transmission between shafts, gears, couplings and other mechanical parts. The design of traditional splines is often based on the designer's experience and international standards, and a large safety margin is set in the design process. In the design process, only the static load on the spline is calculated, and the dynamic load is estimated by the empirical coefficient method. This results in an overly conservative spline design, resulting in a bulky product and a waste of material. The empirical estimation of the dynamic load may also cause the spline to fail when it is subjected to a large impact load, resulting in product damage. There...
