Simulation analysis and optimization design of the wear problem of hinges in tap-hole drill machines

为解决KDIA型开铁口机旋转机构铰链的磨损失效问题,对机构的运动学和动力学仿真建立了机构综合分析平台并以组合磨损计算模型为基础计算相应磨损量.以减缓铰链磨损速度及减轻磨损不均为优化目标,以机构尺寸为设计变量,以不损失其他设计指标为约束条件进行优化设计.结果表明,通过调整设计尺寸以优化机构运动学和动力学性能,是解决传动精度降低、磨损失效等机构问题的有效途径.

To solve the wear failure problem existing in the hinges of the rotary mechanism in a KDIA tap-hole drill machine, a comprehensive analysis platform was established through kinematic and dynamic simulations of the mechanism and the corresponding wear depth was calculated based on a combined wear calculation model. The optimization design was conducted for slowing down the velocity and lightening the unevenness of hinge wear, using the mechanism dimensions as design variables, and no loss of other design specifications as constraints. The results show that optimizing the kinematic and dynamic performance of the mechanism through resizing the design dimensions is an effective way of solving mechanism problems such as transmission accuracy losing and wear failure.
