Non-destructive evaluation method for nonlinear characteristic parameters of hydro-pneumatic suspension

The invention discloses a non-destructive evaluation method for nonlinear characteristic parameters of a hydro-pneumatic suspension, comprising the following steps of: based on the establishment of a bench test for the hydro-pneumatic suspension, representing the nonlinear characteristic curve of the hydro-pneumatic suspension by using a small number of discrete points, wherein the values of the other points on the characteristic curve can be obtained by interpolation of these discrete points, so as to represent that the discrete points on the characteristic curve are optimized variables; by taking the squariance of the difference value between calculated power output and tested power output under various moments as a cost function, searching and evaluating based on an optimized method, so that two characteristic curves can be reversely derived integrally through one test. The non-destructive evaluation method has a simple principle, is convenient to operate during the process of testing, strong in practicability, can effectively provide system parameters for designing a hydro-pneumatic suspension system in real time; in particular, the change of the characteristic parameters and the service performance of an in-service hydro-pneumatic suspension system after being manufactured can be evaluated, thereby having good application prospect.

Wind generating set performance assessment method based on correlation analysis

The invention relates to a wind generating set performance assessment method based on the correlation analysis. The method comprises the following steps that firstly, data are collected through a big-data platform; secondly, a generating set to be analyzed is determined; thirdly, the set in which correlation needs to be determined is subjected to the correlation analysis through different unit wind speeds with time as the sequence; fourthly, a correction unit is selected, and the relative power generating amounts of the correction unit are obtained; and fifthly, the average value of the relative power generating amounts is solved, when the relative power generating amount of the generating set to be analyzed is lower than the average power generating amount (k*100)%, the performance of the generating set to be analyzed is not good enough, and the generating set to be analyzed is in urgent need of rectification, wherein k is a constant. According to the wind generating set performance assessment method, a multi-level correlation and consistency analysis method is utilized, the related unit is determined, the influence of complex wind conditions on the performance assessment is eliminated, the relative power generating amount of the related unit is directly applied to serve as the assessment standard, the influence of good and bad wind resources on power generating is eliminated, and the assessment result is more reliable.
