1) collapse
压塌
1.
The collapse phenomenon during the liquid core reduction in slab continuous casting has been numerically simulated with FEM The influence of liquid core rate, soft reduction rate, ferro static pressure and the internal form of liquid core on the collapse has been investigated It is shown that the collapse is caused by bending of wide side under the action of unstable bulging in narrow sid
用有限元方法 (FEM)对连铸坯轻压下时出现的压塌现象进行了数值模拟。
2) shear plate type overload protector
压塌块
1.
Problems in traditional design theories of shear plate type overload protector are completely and thoroughly analysed.
全面深入地分析了冲床压塌块传统设计理论存在的问题，应用疲劳断裂理论和机械可靠性设计基本理论，深入分析了压塌块剪切破坏工作过程、失效机理及其剪切强度应具备的特性；明确指出压塌块保险系数的选择方法；建立了完整的压塌块机械可靠性设计理论，分析和明确指出提高压塌块工作可靠性和使用寿命的方法。
