Abstract

The invention discloses a simulation realization method of a hydraulic cylinder with an irregular tail end buffering mechanism and belongs to the technical field of hydraulic system simulation. The simulation realization method includes the steps that 1, the throttle area of each buffering stage is determined; 2, a buffering conversion module is established; 3, a complete hydraulic cylinder model with the tail end buffering mechanism is established, wherein the complete hydraulic cylinder model comprises a hydraulic cylinder, a displacement sensor, the buffering conversion module and an adjustable throttle valve; and the displacement sensor collects displacement signals of a piston in the hydraulic cylinder and meanwhile transmits input displacement signal parameters to the buffering conversion module, and the buffering conversion module judges the stages where the hydraulic cylinder is located and computes output signals of all the stages to transmit the output signals to the adjustable throttle valve so as to conduct throttle; and 4, optimization design is conducted on all parameters of the buffering structure of the complete hydraulic model with the tail end buffering structure. The simulation realization method has the beneficial effects that the method is concise and easy to implement, and complete mathematical models can be established conveniently and fast for the irregular tail end buffering mechanism for which it is difficult to establish mathematical models.

Description

technical field [0001] The invention relates to the technical field of hydraulic system simulation, in particular to a method for realizing simulation of a hydraulic cylinder with an irregular end buffer mechanism. Background technique [0002] By simulating the hydraulic system, hydraulic designers can help understand the performance of the hydraulic system in advance, and optimize the design parameters to make the design of the hydraulic system more reasonable, reduce the design cost of the hydraulic system and shorten the development cycle. [0003] In the hydraulic system, the function of the hydraulic buffer (shock absorber) is to prevent the mechanism from being damaged due to hard collision during the working process, and to reduce the noise when the hydraulic cylinder moves in the direction of change. Its basic principle is to rely on hydraulic damping to buffer the objects acting on it. Deceleration to stop, widely used in hoisting transportation, elevators, metallu...
