Most of the XY positioning stages proposed in previous studies are mainly designed by considering only a single performance indicator of the stage. As a result, the other performance indicators are relatively weak. In this study, a 2-degree-of-freedom linear compliant positioning stage (LCPS) is developed by mechatronic design to balance the interacting performance indicators and realize the desired positioning stage. The key parameters and the coupling of the structure and actuators are completely considered in the design. The LCPS consists of four voice coil motors (VCMs), which are conformally designed for compactness, and six spatial leaf spring parallelograms. These parallelograms are serially connected for a large travel range and a high out-of-plane payload capacity. The mechatronic model is established by matrix structural analysis for structural modeling and by Kirchhoff’s law for the VCMs. The sensitivities of the key parameters are analyzed, and the design parameters are subsequently determined. The analytical model of the stage is confirmed by experiments. The stage has a travel range of 4.4 mm× 7.0 mm and a 0.16% area ratio of workspace to the outer dimension of the stage. The values of these performance indicators are greater than those of any existing stage reported in the literature. The closed-loop bandwidth is 9.5 Hz in both working directions. The stage can track a circular trajectory with a radius of 1.5 mm, with 40 mm error and a resolution of lower than 3 mm. The results of payload tests indicate that the stage has at least 20 kg out-of-plane payload capacity.

在含水复杂的地质条件下采用水平冻结法进行盾构进出洞施工,可以通过延长(加深)水平冻结外圈冻结深度,使冻结加固体全方位包裹并超过盾构机本体,利用外圈冻结孔的维护冻结,将盾构推进过程中形成的微小流水通道中的泥土冻结成为冻土,封闭流水通道,较为有效地防止了流水、涌砂现象的发生。利用长距离水平钻孔防喷接驳器,简单方便地解决了在已施工完毕的端头井内长距离钻孔的难题。工程实践证明,全方位风险控制冻结加固技术在复杂地质条件下盾构进出洞施工中,简单易行,安全可靠,值得推广应用。
