Through controlling the step motor moving, the accurate control of the piston pump is obtained. 通过控制步进电机的运动,来实现对柱塞泵流量的精确控制。
This paper introduces STEP and Open Flight, analyzes their inner different. Regarding the piston set of the engine as the applied object, the author discusses some reason about data loss during CAD data converting to virtual model, puts forward the resolve. 介绍了STEP和OpenFlight两种数据格式,分析了它们之间的内在差异,并以内燃机活塞为实例,探讨了CAD模型转换成虚拟装配模型后数据丢失的部分原因,提出了相应的解决办法。
When the piston moves under the sucking action of vacuum, its velocity changes by step way, for the piston pin and rod are connected in turn, and so are their masses. 气缸活塞在真空背压作用下受吸运动,活塞销和连杆的质量是依次连接的这一现状,决定了活塞的速度将呈阶梯式变化。
The final step is to establish the parameters of the radial piston pump system. 最后就是建立径向柱塞泵的参数化系统,实现参数化功能。
