| With the rapid development of China's economy, refrigeration and air conditioning industry has made unprecedented development, but many problems remain to be solved.For the structural design of outdoor unit of air conditioner, whether can develop the corresponding test platform or not has a significant impact to shorten the development cycle and reduce development cost. Qualified products generally need to repeatedly go through piping design, prototype testing, the rectification of piping design, prototype testing to achieve the desired results. The long test cycle and the high test cost will greatly affect product quality and competitiveness.In this paper, force analysis of vibration excitation of air-conditioning compressor and piping system was carried out and the loading method of exciting force was determined. Pro/ENGINEER and ANSYS were used to build the model and carry on dynamic modal analysis and harmonic response analysis of outdoor unit of air conditioner. Test datas were got from the prototype by vibration testing experiment, which were compared with the simulation results. Application software development was based on VC++ application platform. The CAD parametric modeling and finite element analysis were encapsulated in the software. Calculations and results display could be completed automatically.Application achieved the capability of parametric modeling by secondary development of Pro/ENGINEER.Vibration analysis of modeling; simulation and result processing are written with APDL language; FFT transform of the load of harmonic response was carried out by the mixed programming technique of VC and MATLAB.For taking full advantage of the sections of commercial codes, application development process was relatively simple, and the accuracy met the requirements. This application can greatly shorten the product development cycle and cost, which is importance to improve efficiency and competitiveness of enterprises. |
