矿用防爆无轨胶轮车车架动态特性分析
|
摘要
以矿井常用的WCJ12E型交接式胶轮车作为主要的研究对象,针对其车架建立了三维模型,通过胶轮车在一定的运行工况下车架实际受力进行分析,并通过对模型的模拟分析,发现胶轮车车架在通过碎石时会引起一定的激励频率,但是不会发生共振,而胶轮车的发动机则可能会出现共振现象。因此应对发动机的安装进行避振优化设计。
Taking WCJ12 E type alternating rubber wheel car commonly used in mine as the main research object, a three-dimensional model of its frame is established, and the actual force of the frame under certain operating conditions is analyzed by means of the analysis of the actual force on the frame of the rubber-wheeled car under certain operating conditions. Through the simulation and analysis of the model, it is found that the frame of the rubber-wheeled car will cause a certain excitation frequency when it passes through the crushed stone, but there will be no resonance, and the engine of the rubber-wheeled car may have resonance phenomenon. Therefore, the optimal design of vibration avoidance should be carried out for the installation of the engine.
