Support vector machine(SVM) was introduced to analyze the reliability of the implicit performance function,which is difficult to implement by the classical methods such as the first order reliability method(FORM) and the Monte Carlo simulation(MCS).

With this method,the internal force equations are expressed with implicit functions and can be resolved with numerical algorithms.

Machining discal cam using unmerical control system function performance;

Based on the structure reliability analysis and results of structural optimization theory,the performance function and computative method of reliability index of the homogeneous truss structure under certain failure mode were derived and given,respectively.

Aiming at the deployable joints in truss antenna,considering them as separate rockers,breaking up the function,its movement reliability was found to have two parallel performance functions:the performance function according to deploying work and that according to deploying moment.

Structural reliability index for response surface method of RBF ANN was developed,which could resolve the error of structural reliability when the structure performance function was nonlinear or the variables were nonnormally distributed.

This method doesn t have to transform the functional function into the independent standard normal space,and need not the calculation as well on the first ordered and second ordered partial derivative of the logarithm of joint-probability density function,therefore this method is suitable for engineering application.

By using functional function equation,the computing formula of failure mode related correlation coefficient and reliability is given on the basis of the theory of O.

Starting from the probability theory of fuzzy event,the paper briefly introduced the basic thought about application of fuzzy probability vulcanite, constructed functional function used for identification of vulcanite fuzzy probability.
