摘要
针对一款传统的电梯单门刀式门锁装置存在安全缺陷的问题,对处于极端工作状况下的失效原因进行了分析,提出了一种通过修改锁臂零件并增加配重摆锤零件的设计改进方法。在SolidWorks2010平台下,通过运用SolidWorks Motion功能模块,构建了门锁装置的刚体动力学仿真模型,并对极端工作状况和正常工作状况下电梯开门解锁和关门上锁的全过程进行了刚体动力学仿真,确定了配重摆锤重量大小。最后,对两种工作状况下的刚体动力学分析仿真结果与锁臂零件的受力分析状况进行了计算核对,验证了仿真结果的正确性。研究结果表明,改进后的门锁装置达到了消除安全缺陷的目的,设计是有效的。
Aiming at the problem of safety defect on one conventional type of elevator lock device, the failure cause under extreme operation condition was analyzed. The design improving method of modifying arm component and adding counter weight block was advanced. By using functional module, SolidWorks Motion under the platform of SolidWorks2010, the model used for rigid body dynamics simulation was built. After analyzing the dynamics during doors＇ whole process of opening and closing under normal and extreme operation condition, the volume of counterweight was established. At the end, by calculation and comparison with the force analysis situation on the arm component, the result of dynamic analysis is correct. The results indicate that the safety defect is eliminated on the improved design, and it is effective.
