So a cartridge vibration valve is proposed. The valve has a simple structure, which is mainly composed of four two-way cartridge valves, a two-position four-way hydraulic control directional valve and two variable throttle orifices. Its frequency modulation mode is simple, and it can achieve high-frequency commutation and large-flow output. To study the effect of the parameters on the vibration characteristics of the vibration valve, the mathematical model and AMESim simulation model were established. The result shows that: the excitation frequency increases with the increasing of the working pressure, the area ratio and the spring stiffness of the two-way cartridge valve. Adjusting the orifice diameter and the working pressure can regulate the excitation frequency.","PeriodicalId":356055,"journal":{"name":"2017 International Conference on Mechanical, System and Control Engineering (ICMSC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127853584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the bandwidth of transmission channels imposes the limit on the amount of sensor data to be used in remote condition monitoring systems in real-time applications. In this paper, a remote health condition monitoring (RHCM) method based on compressed sensing (CS) is proposed for machine state classification and signal reconstruction. Compressed sensor signals can be directly used to identify different machine states based on a pre-constructed dictionary without the need of traditional feature extraction process. Alternatively, the complete signals can also be reconstructed from the compressed signals and traditional classification approaches can be applied. A case study based on rolling bearing is used to show that the proposed RHCM method can effectively recognize and classify the machine states under different operation conditions using low-volume sensor signals, and the reconstructed signals are accurate enough for post-evaluation or quality assessment of on-site machine process.","PeriodicalId":356055,"journal":{"name":"2017 International Conference on Mechanical, System and Control Engineering (ICMSC)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133750889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a sine curve fitting algorithm with frequency precise estimation is proposed to solve this problem. Firstly, ellipse fitting algorithm is used to estimate the measured signal frequency. On the basis of this, the three-parameter sine fitting calculation based on the least squares method is applied to the sampling data, and the accuracy of the sine curve fitting result is improved. The experimental results show that the algorithm proposed in this paper can avoid the problem of frequency fluctuation and error caused by the unknown relationship between the sampling frequencies. Moreover, the fitting has a good randomness after frequency estimation, and the fitting result has nothing to do with the signal amplitude. Compared without frequency accurate estimation, the fitting error is greatly reduced and the fitting precision is higher.","PeriodicalId":356055,"journal":{"name":"2017 International Conference on Mechanical, System and Control Engineering (ICMSC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121534790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The developed identification method allows to obtain the new structures of feedbacks with respect to the state variables and the parameters by constructing invariants. They allow to formalize a priori uncertainty in the parameters dynamics through the use of additional properties that are exposed at the true trajectory in accordance with the variation method, which follows from the Hamilton — Ostrogradskii principle which is the base for the dynamics of the adaptive system and the parameters. The variations properties allow to decompose the identification system into the subsystems of the parameter and status estimation. The relationship between them is determined by the equation for the sensitivity function. The constructiveness of the synthesized algorithms of identification is confirmed by the results of solution the problem of identifying the parameters of the nonlinear dynamic system regulator.","PeriodicalId":356055,"journal":{"name":"2017 International Conference on Mechanical, System and Control Engineering (ICMSC)","volume":"60 48","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114005828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
