Abstract

This paper presents the findings of a comprehensive study of the effects of various design variables on the dynamic behavior and vibration characteristics of a front-loading washing machine. A multibody dynamics model of the washing machine with a set of 9 key design variables is developed using the commercial multibody simulation software Adams View. The design variables are implemented to enable automated modifications of the dynamics model for certain parameters such as the geometric orientations of the springs and dampers in the washing machine. This dynamics model is employed to perform a series of numerical simulations by considering a range of parametric values for the design variables. Numerical convergence analysis is performed to ensure that the simulation solutions are converged. Using the simulation solutions, the time histories of displacements at select points of the washing machine during operation (from transient till steady-state motion) are analyzed to understand how the natural frequencies of the washing machine are affected by various design variables. Finally, a sensitivity analysis is carried out to determine the design variables that have the strongest impact on the dynamic behavior of the washing machine. Of all the design variables affecting the dynamic behavior of the washer model, the weight balancer mass density and the damping coefficient were found to have the strongest effect.

综合研究了各种设计变量对前装式洗衣机动力性能和振动特性的影响

本文全面研究了各种设计变量对前装式洗衣机动态特性和振动特性的影响。使用商用多体仿真软件Adams View开发了洗衣机的多体动力学模型，该模型包含9个关键设计变量。设计变量被实现为使得能够针对某些参数自动修改动力学模型，例如洗衣机中弹簧和阻尼器的几何定向。该动力学模型用于通过考虑设计变量的一系列参数值来执行一系列数值模拟。进行了数值收敛性分析，以确保模拟解的收敛性。使用模拟解决方案，分析了洗衣机在运行过程中（从瞬态运动到稳态运动）选择点的位移时程，以了解洗衣机的固有频率如何受到各种设计变量的影响。最后，进行灵敏度分析，以确定对洗衣机动态行为影响最大的设计变量。在影响洗衣机模型动态性能的所有设计变量中，重量平衡器质量密度和阻尼系数的影响最大。
