摘要:
为研究转速与负载对RV减速器振动特性的影响，建立RV-40E型减速器刚柔耦合虚拟样机模型。首先，基于ANSYS建立RV减速器力学模型并进行模态计算，得到其主要零部件的固有频率与相应振型；然后，利用ADAMS软件对样机模型进行多体动力学分析，并对结果进行时域与频域分析。分析结果表明：容易引起RV减速器整机共振的固有频率段为2929.6，2938.9，3162.8 Hz；受转速影响，同一梯度内加速度曲线幅值涨幅在16%以内，负载影响下，同一梯度内加速度曲线幅值涨幅在20%以上，相较于转速而言，受负载改变影响曲线波动幅度变化较大。研究成果为进一步提高RV减速器力学性能、降低振动噪声提供依据。
Abstract:
In order to study the influence of speed and load on the vibration characteristics of RV reducer,a rigid-flexible coupling virtual prototype model of RV-40E reducer was established.Firstly,based on ANSYS,the mechanical model of RV reducer was established and the modal calculation was carried out.The natural frequencies and corresponding vibration modes of the main components of RV reducer were obtained; then,the multi-body dynamics analysis of the prototype model of the reducer ·0was carried out by using ADAMS software,and the calculation results were analyzed in time domain and frequency domain.The influence of speed and load on the vibration characteristics of RV reducer was studied.The results show that the natural frequencies that easily cause the resonance of RV reducer are 2929.6,2938.9 and 3162.8 Hz; the speed has little effect on the vibration characteristics of the reducer,while the load has a significant effect on the vibration characteristics of the reducer；Affected by the speed,the amplitudes of the acceleration curves in the same gradient increases within 16%.Under the influence of load,the amplitudes of acceleration curves in the same gradient increases by more than 20%.Compared with the speed,the fluctuation range of the curves was larger and the change range was obvious due to the change of load.The research results provide the basis for further improving the mechanical properties of dynamic RV reducer and reducing the vibration noise.
