Virtual Manufacturing (VM) is a concept of executing manufacturing process in computers as well as in the real world,where virtual modes allow for prediction of potential problems for product functionality and manufacturability before real manufacturing occurs.As a new manufacturing technology,VM affects the whole manufacturing industry including the manufacture of high-speed photograph camera (HSPC).The application of VM successfully resolves a series of technical difficulties caused by increasing photograph frequency of HSPC.These efforts of VM can not only increase the level and overall design quality of HSPC manufacturing,but also decrease the development cycle.At the same time,a new tool for key technology analysis and design solution in the field of HSPC manufacture is provided.For an example,a kind of HSPC is listed as follows.It has been studied in a virtual environment through the design,assembling,dynamic analysis and movement simulation procedures.
