摘　　要：为了尽可能减少滑动门板运行失效,利用仿真软件对空调器的滑动门板机构进行动力学仿真分析,并结合理论分析及试验测试验证仿真结果的准确性。首先用creo软件初步设计好运动门板运动机构三维模型,再将其导入ANSYS软件中进行动力学仿真分析,结果表明运动门板总体运行平稳、机构满足强度设计要求、齿轮齿条柔性接触的最大应力为0.5 MPa,但门板启动阶段及打开的极限位置相对容易发生结构破坏,另外齿轮齿条接触区域、齿条与推板及插销接触部位等几个应力集中区域需要避免出现缩孔、缩松等缺陷。最后通过赫兹理论计算及试验测试结果也验证了模拟仿真结果的可靠性,为空调运动门板运动机构的研发提供理论参考。In order to reduce the possibility of failure of the sliding door mechanism during the design phase,ANSYS software was used to conduct dynamic simulation analysis of the air conditioning sliding door mechanism,and the accuracy of the simulation results was verified through theoretical analysis and experimental testing.Firstly,a preliminary 3D model of the sliding door motion mechanism was designed using Creo software,and then imported into ANSYS software for dynamic simulation analysis.The results showed that the sliding door ran smoothly overall,the mechanism met the strength design requirements,and the maximum stress of flexible contact between gears and racks was 0.5 MPa.However,during the start-up stage and the extreme position of opening the door panel,structural damage was relatively easy to occur.In addition,the contact area between gears and racks Several stress concentration areas,such as the contact part between the rack and the push plate and the pin,need to avoid shrinkage cavity,shrinkage porosity and other defects.Finally,the reliability of the simulation results was verified through Hertz theory calculations and experimental testing results,providing a theoretical reference for the development of the sliding door motion mechanism of air conditioning.
