Firstly, the paper introduced the working principle and device of the two-pass grate-rotary kiln and had an analysis method of mechanics of the tyre. We have put forward the finite element analysis of the contact stress of the tyre-roller based on the whole construction mode of shell-kiln liner-large gear-tyre-roller of the rotary kiln and obtained the strength and distributing rule of the tyre's contact stress. The research shows that within one week the contact stress mainly lies in two leading peak value and catastrophe which appear at the contact zone of the tyre and supporting roller. Then we regarded the tyre's stress as the test of unknown plane stress of principal stress. Utilizing mature and modern testing technology, we raised the testing principle and scheme of tyre stress and then had a on-the-spot test of the stress. Comparing the analysis result of the test with the one calculated from the finite element analysis, it proofed the rationality of finite element analysis method of integral modeling and the correctness of the contact stress result of the tyre and roller. Finally, for two-pass of similar rotary kilns, using the ANSYS APDL re-development technology, carried on the re-development about the overall finite element analytic method of thecontact stress of tyre-roller.

首先，本文介绍了2档回转窑的工作原理和装置，对滚圈的力学行为进行了分析，提出了基于筒体-滚圈-托轮的回转窑整体建模的有限元分析法，来对滚圈-托轮的接触应力进行有限元分析与计算，得到了滚圈接触应力的大小和分布规律，并求得滚圈外中内圈节点的主应力；其次，把滚圈的受力看成是主应力未知的平面应力的测试，利用现代测试技术，提出了滚圈主应力测试的原理和方案，并对滚圈的主应力进行了现场测试，现场测试分析结果与有限元分析计算出的主应力相比较，证明了整体法建模的有限元分析方法的合理性和滚圈-托轮接触应力结果的正确性；最后，利用ANSYS的APDL的二次开发技术，针对2档同类回转窑，就滚圈-托轮接触应力的整体有限元分析法进行了二次开发。

The tongs all passes in the machine the gearing on the bed what tongs the gearing on realizes with superficial contact in the cowgirl on the bed in machine or matches.when the tongs installs in the machine bed work on the stage,the center of gravity of the tongs should be as far as possible low,center of gravity the more high an accepts should the dint is more big,the tongs bottom four directions should bulge,make its contact good,or the bottom establishes four a feets.when the tongs installs on the machine bed principal axis,the tongs install the to should have the enough match accuracy with principal axis cowgirl surface,and guarantee the gearing the stability dependable.

夹具体在机床上的安装都是通过夹具体上的安装基面与机床上的相应表面的接触或配合实现的。当物流设备需要的公司体在机床工作台上安装时，夹具的服装厂应尽量低，重心越高则支承面应力越大，夹具底面四边应凸出，使其接触良好，或底部设置四个支脚。当夹具体在机床主轴上安装时，夹具安装基面与主轴相应表面应有足够的配合精度，并保证安装稳定可靠。
