【摘要】：针对液压支架顶梁笨重、耗材的弊端,提出了基于ANSYS/OPT模块的轻量化设计方法。轻量化设计前的顶梁最大米塞斯应力为933.67 MPa,超出材料的许用应力,应用ANSYS/OPT模块对顶梁进行结构尺寸优化,使其在满足液压支架设计准则的前提下,对原有的顶梁模型进行改造,改造后的顶梁最大等效应力为632.667 MPa,整体质量减少了12.27%;最后利用ANSYS/PDS模块对优化后的顶梁的可靠度进行近似计算,结果表明顶梁的可靠度为97.8%,满足工程要求,为顶梁的优化设计提供了科学依据。
[Abstract]:A lightweight design method based on ANSYS/OPT module is proposed to solve the drawback of heavy top beam and consumable material of hydraulic support. The maximum Mises stress of the top beam before lightweight design is 933.67 MPA, which exceeds the allowable stress of the material. The ANSYS/OPT module is used to optimize the structure size of the top beam, so that the original top beam model can be modified on the premise of satisfying the design criteria of hydraulic support. The maximum equivalent stress of the retrofitted beam is 632.667 MPA, and the whole mass is reduced by 12.27%. Finally, the reliability of the optimized top beam is approximately calculated by using ANSYS/PDS module, and the result shows that the reliability of the top beam is 97.8, which meets the engineering requirements. It provides a scientific basis for the optimum design of the top beam.
