ANSYS多圈管2D冻结温度场分析，根据对称性，选择第一象限进行模拟。 命令流中有详细说明！ ZTIME=540           !冻结时间 Ld=10000            !如果某荷载步的温度等于Ld，则表示该荷载步不加载，直到下一荷载步 KBCVALUE=1          !KBCVALUE=0为坡道加载,KBCVALUE=1为阶跃加载 THETA=90            !所计算扇形区的圆心角,单位为度。一般取为第一圈孔的主面与界面的夹角（保证井内温度场基本不受影响）                     !该范围内每圈孔至少有3个管，否则可能在捕捉图时有点小问题, GA=THETA*1/1        !应确保GA的范围内每圈冻结管至少有2个.

说明：  本文介绍了一种新型变刚度执行机构(CompAct-VSA)的设计与建模。压实- vsa的工作原理是基于具有连续调节枢轴点的杠杆臂机构。提出的概念允许开发具有大刚度范围和快速刚度调节响应的驱动单元。执行机构的实现利用凸轮形杠杆臂与可变枢轴驱动齿条和小齿轮传动系统。这种实现导致了高度集成和模块化的组装。尺寸和重量确实是VSAs设计中的一个开放问题，这最终限制了它们在多自由度机器人系统中的实现。本文介绍了执行机构的原理、工作原理和模型。初步结果表明，所提出的压实vsa设计具有快速的刚度调节响应和较大的刚度范围。(This paper describes the design and modelling of a new variable stiffness actuator (CompAct-VSA). The principle of operation of CompAct-VSA is based on a lever arm mechanism with a continuously regulated pivot point. The proposed concept allows for the development of an actuation unit with a wide range of stiffness and a fast stiffness regulation response. The implementation of the actuator makes use of a cam shaped lever arm with a variable pivot axis actuated by a rack and pinion transmission system. This realization results in a highly integrated and modular assembly. Size and weight are indeed an open issue in the VSAs design, which ultimately limit their implementation in multi-dof robotic systems. The paper introduces the mechanics, the principle of operation and the model of the actuator. Preliminary results are presented to demonstrate the fast stiffness regulation response and the wide range of stiffness achieved by the proposed CompActVSA design.)
