摘要
根据GB7121—86的驾驶室安全强度验收标准,用弹塑性理论和非线性有限元方法,建立了驾驶室的数学力学模型,并进行了模拟计算,据此,可以实现对轮式拖拉机驾驶室的安全强度预估。
According to GB7 121 - 86 for the structure safety of tractor cab and with the theory of elastic and plastic mechanics and finite element method ,the mathematics and mechanics model of a cab has been created and calculated. So the structure safety of the tractor cab can be estimated in design stage.
