This thesis presents the studies of U-shape gantry structure of container gantry crane, and dynamic simulation and fatigue life estimation of its rigid anti-sway. The main contends are as follows: Supposed that trolley frame is composed of spring structure, due to larger trolley gauge of U-shape gantry structure. For the gantry crane, a series spring dynamic vibrating model with three masses, three freedoms of degrees is built in this thesis and vibrating calculus equations are precisely resolved by mode analyses rule.

本文研究集装箱门式起重机U型门架结构及其刚性减摇系统的动态仿真和疲劳寿命估算，主要内容如下：由于U型门架结构小车轨距较大，本文建立了考虑小车架为弹性结构时门式起重机的三质量三自由度串联弹性动力学振动模型，用模态分析法求解振动系统微分方程组的数值精确解。

On some occasions,two-step orthogonal toggle force-amplifying press based on pneumatic-mechanical compound transmission systems can be used instead of hydraulic transmission systems that cause environmental pollution.

而气压传动系统中的工作介质，是洁净的压缩空气，从这一点上来说，气压传动可以说是一种绿色化的传动技术。目前也有少量压力机采用气压传动，但是都是使用有杆活塞缸，这种气缸一般刚性比较差，且空间利用率低。

Two interface agents had different effects on the mechanical behaviors which might bring them both promising application.Since application of clay/SBR nanocomposites in the tire tube is a main trend, the processing properties of clay/SBR nanocomposite were investigated by means of Monsanto Rheometer and RPA.

采用FTIR对马来酸酐和粘土之间的反应进行了表征，发现粘土与马来酸酐发生了反应；采用DSC对丁吡橡胶与粘土之间的结合进行了表征，表明丁吡橡胶可以使填充粘土胶料中产生一定程度的刚性结构。

Concrete methods are: 1.4mm thick film will be changed to 4mm thick rigid films, the next cavity pad 0.05mm thick tin-foil, so that spindle adjusted to the higher than the ideal position 0.05mm position.

具体作法是：将1.4mm厚的膜改为4mm厚刚性膜，在下腔垫0.05mm厚的锡箔纸，使主轴调整到比理想位置高0.05mm的位置。
