Because of the gun comprehensive performance detection means backward, and unable to meet the maintenance and support needs, we analysis on the artillery and comprehensive index. The detection system for the breechblock and anti-recoil mechanism and aimed machine is designed. Using advanced hydraulic control technology, realize the technical indicators detection under recoil process. The performance status before repair and repair quality are completely grasped. Its proved in the application this system runs stably and reliably.

The Common

The common swimsuit fabrics on the market are mainly polyamide/ spandex, polyester/ spandex blended at present, which have some defects such as easy deformation, short service life etc. Sorona is a new kind of biomass fiber with low carbon and environmental protection, which has more superior performances than spandex that could ensure the fabric elastic lasting and stable. The paper uses seamless technology to weave new polyamide/ Sorona/ spandex swimsuit fabric, and compare with the ordinary polyamide/ spandex, polyester/ spandex fabric, by testing the specimen of tensile elasticity, elastic recovery and plasticity deformation rate, burst strength, and many other swimsuit related performance metrics. Come to conclusions: polyamide/ Sorona/ spandex fabric with superior elasticity, good comprehensive performance of elastic recovery and plastic deformation rate, excellent burst resistant performance , small hygroscopicity and fine permeability is suitable for swimsuit fabrics, providing reference for the development of high comfort seamless swimwear fabric.

Axial Piston

The axial piston pump is an important industrial power element, and its performance directly affects the operation of the system. However, owing to its complex structure and harsh operational environment, the actual operational performance of the axial piston pump is difficult to be assessed accurately, which makes ensuring the normal operation of the hydraulic system difficult. To improve the evaluation method for an axial piston pump, a comprehensive performance evaluation system was proposed based on analytic hierarchy process (AHP), which could assess the performance of an axial piston pump on the basis of theoretical analysis, test, operator interaction, and application. Considering a model of load-sensitive axial piston pump with good operability as an example, the model development and simulation of the pump were carried out based on AMESim and the pump was tested using a developed performance test bed for axial piston pump. The weights of factors in the evaluation system were determined on the basis of the simulation results, analyses, and calculation. The above results were used to comprehensively analyze the tested pump and design a set of comprehensive performance evaluation software. The evaluation result was nearly identical to the actual usage, which verified the feasibility of the designed evaluation system.
