提出了汽车冷凝器散热器风扇模块(CRFM)安装系统的设计要求。建立了六自由度CRFM模型。提出了一种确定冷却风扇激励下CRFM悬置系统悬置反力均方根值的计算方法。讨论了在极端载荷作用下CRFM位移控制的设计计算方法。鲁棒性分析是通过实验方法的设计。最后,根据CRFM悬置反力和重心位移的设计要求,给出了悬置刚度和调整点的计算实例。通过算例验证了直线段悬置刚度对CRFM固有频率、能量分布以及悬置反力均方根值的影响。
Design requirements of automotive condenser radiator fan module (CRFM) mounting system are proposed. A six degrees of freedom (DOFs) CRFM model is established. The calculation method for determining the root mean square (RMS) value of mount reaction force in a CRFM mounting system under cooling fan excitation is developed. Design and calculation methods for displacement control of the CRFM under extreme load are discussed. Robustness analysis is presented through a design of experimental method. At the end of this paper, a calculation example is proposed to get the mount stiffness and tuning point based on the design requirements for mount reaction forces and displacement of the CRFM centre of gravity. Effects of mount stiffness at linear section on natural frequencies and energy distributions of the CRFM and on RMS value of mount reaction forces are validated by a generic example.
