Problems solved by technology

If the suction and exhaust pipes of the compressor use steel-woven metal bellows, the two ends of the steel-woven metal bellows need to be welded to the existing pipeline system separately, which increases the secondary costs of welding process man-hours, welding labor positions, and welding materials.
If there is a need to make samples for testing every time there is a new piping scheme, it will not only waste a lot of materials, but also take too long to manufacture and assemble and affect the progress of the project
[0004] Furthermore, the original piping scheme does not use steel-woven metal bellows, which may cause excessive stress on the pipeline, and the pipeline is prone to cracks or even breaks during the trial process, reducing the service life of the air conditioner

Abstract

The invention belongs to the technical field of passenger car air conditioner compressor accessories, and discloses a novel matched pipe of an exhaust pipe, a derivative structure, a passenger car airconditioner compressor and a simulation method. For a possible optimization and improvement scheme, CAE simulation software is used for building a virtual model to conduct transverse comparison; CAEsimulation analysis is carried out on an exhaust pipeline assembly to carry out structural optimization by using parameters such as the lengths of multiple straight pipe sections L and the bending angles of multiple exhaust pipe bends as variables and using the lowest stress strain of the pipeline as the target, and thus several pipeline arrangement schemes with low stress are obtained; and samplepreparation, test and comparison are carried out on the pipeline schemes obtained by CAE analysis. According to the method, CAE simulation analysis is combined with experimental verification, so thatthe problem that an original matched pipe optimization scheme consumes a large amount of time is solved, the method combining CAE simulation and experimental testing is used, the advantages and disadvantages of the multiple schemes can be rapidly compared through the CAE simulation analysis, and the accuracy of results can be guaranteed through experimental testing.

Description

technical field [0001] The invention belongs to the technical field of accessories for passenger car air-conditioning compressors, and in particular relates to a new type of piping for an exhaust pipe, a derivative structure, a passenger car air-conditioning compressor and a simulation method. Background technique [0002] At present, during the operation of the pipeline of the passenger car air conditioner, in addition to being excited by the compressor during normal operation, it is also excited by the vehicle body itself and the road surface during the driving process of the vehicle. It is even worse for a flat general household air conditioner or commercial air conditioner, so the piping of its refrigeration unit is more complicated and difficult. In order to improve the reliability of the system and reduce the stress and strain of the pipeline, the existing passenger car air conditioner usually adopts the scheme of adding two steel-woven metal bellows at the suction and...
