The present invention discloses a distributed collaborative reliability method for a multi-failure structure based on subject decomposition, which is applied to the field of aircraft engine reliability technology. The method comprises the following steps: first, the various failure modes of the multi-failure structure are disassembled according to the subjects to which they belong, the response analysis of a single subject is carried out, and a distributed proxy model of the response of each subject is established; then, the response of each subject is extracted in linkage by using the collaborative sampling technology, and the distributed collaborative reliability analysis of the multi-failure structure is completed by using the established distributed proxy model; finally, the reliability analysis results of the multi-failure structure are imported into the Copula correlation model, and the correlation between multiple failure modes is evaluated by simulation results. Compared with the prior art, the present invention combines the distributed collaborative proxy model based on subject decomposition with the Copula function that can quantitatively quantify the correlation, which not only accurately quantifies the failure correlation between each failure mode, but also ensures high calculation accuracy and efficiency.

This invention discloses a flexible and rigid connection structure and its usage method suitable for aerial work platforms, comprising four flexible connection mechanisms and four rigid connection mechanisms. One of each mechanism is installed at each of the four corners of the U-shaped aerial work platform. The four flexible connection mechanisms connect the four independent platforms corresponding to the U-shaped aerial work platform into a whole during the lifting process. The four rigid connection mechanisms are designed to be detachably connected between any two adjacent independent platforms, and are used for disassembly and fixing during the lifting process and after the U-shaped aerial work platform has reached the designed position. This invention achieves overall platform lifting by setting flexible connection mechanisms on the long platforms inside and outside the tower and using wire rope traction for the telescopic platform, thus solving the problem of buffering against external impacts. After the long platforms inside and outside the tower and the telescopic platform are in position, a rigid swing-arm connection mechanism connects the aerial work platform into a whole, effectively solving the problem of overall stability.

This invention discloses an electroplating apparatus and an electroplating production line, comprising: an electroplating tank and a clamping and conveying structure; wherein, the clamping and conveying structure is disposed on the open side of the electroplating tank; the clamping and conveying structure conveys the film to be coated along the conveying direction, and the clamping and conveying structure includes at least two sets of clamping and conveying mechanisms; each clamping and conveying mechanism includes an electroplating clamp, a closing clamp assembly, and an opening clamp assembly; on one clamping and conveying mechanism, the closing clamp assembly and the opening clamp assembly are disposed at both ends of the clamping and conveying mechanism along the conveying direction; along the conveying direction of the film to be coated, the closing clamp assembly and the opening clamp assembly of two adjacent clamping and conveying mechanisms are spaced apart and form an adjustable interval. This structure, by providing an adjustable interval, corrects the error caused by the asynchronous electroplating clamps in the previous clamping and conveying mechanism when the film to be coated enters the next stage of the clamping and conveying mechanism; thus greatly solving the synchronization problem.
