Embodiment Construction
[0065] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0066] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0067] The method of the present invention is based on the creo2.0 three-dimensional design software to parameterize the three-dimensional model of the flow channel of the hydraulic torque converter, such as figure 1 shown.
[0068] 1) Parameterization of the actual circulation circle of the hydraulic torque converter.
[0069] The shape formed by the cross-section through the axis of the torque converter and the boundary line connected with the liquid on the cross-section is called a circular circle. Due to the symmetry of the axis of symmetry, generally only half of the axis is drawn. When designing the circulation circ...

The invention discloses a parameterization method for hydraulic torque converter channel models. The parameterization method comprises the steps that an inner ring and an outer ring of an actual circulating circle of a hydraulic torque converter are parameterized; pump impeller blade-free channels and turbine blade-free channels are parameterized; pump impeller blades and turbine blades are parameterized; combination treatment is conducted to obtain a parameterized pump impeller whole-channel model and a parameterized turbine whole-channel model; guide wheel blade-free channels are parameterized; guide wheel blades are parameterized; combination treatment is conducted to obtain a parameterized guide wheel whole-channel model; the pump impeller whole-channel model, the turbine whole-channel model and the guide wheel whole-channel model are assembled according to the coordinates to obtain a parameterized hydraulic torque converter full-channel model; the hydraulic torque converter full-channel model is cut into the single-channel models, and simulating calculation is provided for development of the hydraulic torque converter. The parameterization method has the advantages that the development efficiency is improved, the development time is shortened, and theoretical guidance is provided for parameterization design of the calculation models.
Description
technical field [0001] The invention relates to the technical field of automobile hydraulic torque converters, in particular to a parameterization method of a fluid channel model of the hydraulic torque converter. Background technique [0002] The hydraulic torque converter is a hydraulic component that uses the kinetic energy of the liquid for energy transmission, and is one of the most important components of the automatic transmission system of a car. Cars equipped with hydraulic torque converters have many advantages such as good self-adaption, passability and low-speed driving stability.
