Title: Air conditioning scroll compressor starting characteristics optimized rotor noise and vibration control ofAuthor: Qi JilongDegree-granting units: Jilin UniversityKeywords: rolling piston compressor;; permanent magnet synchronous motor;; sensorless control;; noiseSummary:In this paper, and Qingdao fast to the company's cooperation project "air conditioning compressor controller software development" topics, the main study space
Call the rolling piston compressor drive neodymium magnets and performance optimization issues. Through this study to optimize the compressor starting process,
Proposed to improve the performance of the compressor vibration and noise program. This work is divided into the following sections.1, turn by rolling
Sub compressor characteristics and working principle of the structural analysis, simulation of the rolling rotor compressor suction chamber in the work of cavity pressure and compression
Strong changes, and changes in pressure and vane rotor and other parts of the force acting on the rolling machine with rotor angle changes. Established a rolling turn
Sub-type compressors work load torque resistance model.2, the compressor through the simulation model tested the open-loop start-up programs, and
By increasing the resistance constant torque http://www.chinamagnets.biz/Neodymium/Ball-Neodymium-Magnets.php load and compressor load to debug and improve the starting performance of the compressor. Verified through simulation mentioned
Start-up programs and the reasonableness of the various parameters involved in the testing method.3, in order to improve the rolling piston compressor starting performance, the
Paper presents a DSP chip using relatively simple methods and start to build a test system. Through theoretical analysis and experimental advantages of repeated
Of the starting process of the acceleration curve, starting the compressor to shorten the process time, enhanced reliability, even under pressure in the smaller
Smooth start.4, in order to improve the rolling piston compressor noise and vibration performance, proposed to improve the compressor's drive from the effects of
Vibration and noise of the compressor performance improvement program. Confirmed by simulation using the torque side of the control system, speed side
Control and change programs to reduce the sampling time course of the compressor drive speed fluctuations. This article also driven by different
Dynamic system in the interior of the compressor-driven silencer vibration and noise performance is tested. The results show that the use of different drive systems for pressure
Machine vibration and noise reduction performance has a significant impact.Degree Year: 2009
