Finite Element Analysis and Design of Comb Inspection for Escalator

为了解决检测自动扶梯梳齿板保护开关是否有效过程中需要人工暴力性检测且无法得到有效力学数据的问题,通过分析梳齿板保护开关检测的现状需求,设计一种检测装置。利用虚拟样机技术,基于三维软件设计平台,对自动扶梯梳齿板检测装置进行三维参数化建模,通过有限元法对检测装置的核心部件——传感器推拉支架进行材料力学分析,得出屈服应力和挠度位移形变结果,根据安全设计规范对其材料特性进行比较和验证,确定设计方案的合理性和有效性。

In order to determine the neccessity to apply manual violence detection for the protection switch of the comb plate of escalator in its effective period and abtain effective mechanical data,a detection device is designed by analyzing the current detection requirements of the comb plate protection switch.With virtual prototyping technology and based on the Three-dimensional software design platform,the three-dimensional parametric modeling of the escalator comb plate detection device is carried out.The finite element method is applied to conduct the material mechanics analysis on the pull and push support of the sensor of the core component of the testing device,so as to abtain the results of yeilding stress,deflection displacement shape.In line with safety design code,the material characteristics are compared and verified for determing the safety,rationality and effectiveness of the design scheme.
