Introduction

In the hydraulic transmission system, the power is transmitted and controlled by the pressurized fluid in the circuit. due to fatigue failure modes associated with hydraulic components The safety function of the hydraulic components is closely related to the working life, so for the manufacturers and users of hydraulic components, it is obvious to master the reliability data of hydraulic components. very important. This document provides a method for validating fatigue pressure evaluations of hydraulic component pressure housings. During operation, components within the system may be subjected to loads from. --- Internal pressure; ---external force; --- the effects of inertia and gravity; --- shock and vibration; --- Temperature changes or temperature gradients. The nature of these loads can range from a single static force to continuously varying amplitudes, repetitive loading, and vibration. Find out if the component can withstand These loads are important, but this document only deals with loads caused by internal pressure. This document provides a general verification method for improving component stress evaluation for the various stress evaluation methods employed by manufacturers. reliability. The verification method is based on the statistical analysis and statistical verification theory of metal fatigue. In order to improve the accuracy of this verification method, we have It is necessary to combine the design structure principles of each type of component and its typical test sample. Regardless of the size of the sample, this verification method can reduce the hydraulic element risk of fatigue failure. To verify the rated fatigue pressure of the components according to this document, the rated fatigue pressure of the components should be preliminarily set, the test samples should be selected and the Test pressure; then carry out fatigue pressure test according to GB/T 19934.1.If the sample test is successful, it indicates the fatigue of this type of hydraulic components The stress evaluation was validated. Fatigue Pressure of Hydraulic Transmission Metal Pressure-bearing Housing Test evaluation method

1 Scope

This document gives the fatigue pressure evaluation of metal pressure-bearing housings of hydraulic components under continuous stable and periodic internal pressure loads. price method. This document applies only to fabrication of metal, operation at temperatures that do not produce creep and low temperature embrittlement, stress induced only by pressure, not There are hydraulic element pressure housings that have reduced strength due to corrosion or other chemical effects. The pressure housing may include gaskets, seals and Other non-metallic parts, but these parts are not used as part of the pressure-bearing housing of the tested hydraulic components (see GB/T 19934.1). This document does not apply to piping components (i.e. fittings, hoses, rigid pipes) specified in ISO 4413.Fatigue testing for piping components See GB/T 26143, ISO 6803 and ISO 6605 for methods. This document presents a general method for fatigue pressure evaluation of metallic pressure-bearing housings for hydraulic components. In addition, EN14359 for storage Specific methods and test requirements are described in Fatigue Pressure Evaluation of Energy Equipment.
