Design of a device for the analysis of hydraulic damper valves
Čupr, Martin ; Jeniš, Filip (referee) ; Macháček, Ondřej (advisor)
The bachelor thesis deals with the design of a device for a stand-alone hydraulic damper`s valve analysis. The main goal is to construct a jig, where the valve is firmly attached, so it can be exposed to high-pressure oil flow, simulating the real conditions in a damper. In this thesis, the valves of the two specific hydraulic dampers were chosen. The jig was designed to enable testing of these valves loaded by operating pressure up to 32 MPa. As the jig is universal, it allows testing of any similar-sized valves. Moreover, it provides the possibility to test two valves at the same time and analyse their cooperation. The jig presented in this thesis was designed for the development purposes. However, the same principle can be used as a control jig in serial manufacture. This approach enables to measure both the valve`s pressure drop and the current volumetric flow rate of oil. Consequently, all the main characteristics of the valve which are derived from these two quantities can be invetigated. When the cooperation of two valves is analysed, the ration between volumetric flow rates in each valve can be determined.
