摘要
就勘探新测井设备中的关键部件推靠装置进行了论述。设计了一种新的适合测量250～400mm井径范围的测井仪推靠装置，应用几何原理和受力平衡理论分析了机构的性能，并用ADAMS软件对结构进行了运动学和动力学仿真。理论分析证明该机构具有结构简单、可靠性高、运动准确、推靠力大等特点。运动学仿真得出机构推靠臂张开的最佳速度为50—80mm／s；动力学仿真说明机构在给定的理论扭矩下产生了预期的推靠力。通过仿真分析说明了新机构的可行性。
The pushing device, key component of logging instrument, is discussed. A kind of new pushing device is designed so that wells with diameter range from 250 millimetres to 400 millimetres can be measured by the new device and its structural performance is analysed by using the geometric principie and the principle of balance and then a kinematics and dynamics simulation is made for the structure through software ADAMS. The results of analysis show that the new device has characters as follows： simple structure, high reliability expanding speed of the pushing , moving accurately and the great pushing force and so on. An optimum device arms is in the range of 50 millimetres to 80 millimetres per second according to the kinematics simulation; as is shown in the dynamics simuLation, we can know that the mechanism can produce anticipant pushing power at given theoretical torque. The feasibility of the new mechanism is illustrated by the simulation above.
