Differential Equation and Analytic Computation of Throttle Slice Deformation under Micro-Circle Pressure

Abstract:

It has been a key problem that the analytical computation of a throttle slice deformation, for the design of shock absorber valves parameters. In this paper, the mechanics model of throttle slice under a spring pre-tightening was simplified into that under a micro-circle pressure. Using boundary and continuity constraints, the general equation for throttle-slice deformation under a micro-circle pressure was given, and by mathematical transformation, an analytical formula was established. With the practical example, the deformation of throttle slices on spring pre-tightening force at any radius was computed, and was testified by ANSYS. It is known that the results computed are close to that simulated, and the deviation is only 6.6 mm. It is shows that the method of deformation analysis of a throttle slice under micro-circle pressure is reliable, which has important reference value for throttle valves parameters design and characteristic simulation of shock absorbers.
