摘要: 具有地面摩擦约束的脚轮-除湿机系统的平动刚体模态对除湿机振动有较大影响。为了研究脚轮对刚体模态影响规律,采用刚柔耦合方法对除湿机进行整机建模,仿真计算脚轮-除湿机系统的平动刚体模态,通过刚体模态试验校核仿真模型。模态分析表明,脚轮尺寸、材质、结构型式、与地面摩擦力等均会影响刚体模态的固有频率,其中,改变脚轮方向,摩擦力随之变化,导致刚体固有频率波动。在最不利方向上,刚体固有频率与压缩机激励频率接近,除湿机水箱振动最大。在此基础上,计算不同脚轮方案的整机动力学响应,并进行优选,最终在除湿机振动满足内控标准的基础上,实现水箱振动波动度降低55%。

Abstract: The vibration characteristics of the caster-dehumidifier system with ground friction constraints are strongly correlated with its translational rigid body modes. The influence of casters on rigid body modes was investigated by simulations of the entire dehumidifier system, which was modelled with a rigid-flexible coupling method and verified by experimental results. It was shown that the natural frequency of the rigid body mode is influenced by dimensions, material, structural configuration, and ground friction of the caster. Note that alterations of the caster orientation influence the rigid body natural frequency due to the change of friction characteristics. In the most unfavorable orientation, the rigid body natural freed on the investigations, the practical caster systems were selected according to the simulatquency approached the compressor excitation frequency, resulting in maximum water tank vibration. Based dynamic responses. As a result, the water tank vibration fluctuation was reduced by 55% on the condition that the internal vibration control standards are satisfied.
