| Abstract: | Based on the parellel mechanism,the operating principle of a new type measuring device is introduced. The calculation expressions of geometrical parameters is derived and the related parameters of this mechanism is established based on the analysis of the kinematic geometrical relationship. The whole mechanical component of this system is devised. Through the analysis of corresponding single error factors,the source for the error compensation is found so that this sensor embedded working mechanism under the common manufactural circumstance can meet the technical requirements with a high precision and has a certain practical value. |
