英文摘要：
The optimization design for kinematic accuracy reliability of shaping mechanism under incomplete probability information is extensively discussed in this paper by combining the reliability theory and optimization technology, and a numerical method for reliability--based optimization design is proposed. Under the condition that the first four moments of basic random parameters are available, computer programs based on this model can complete the reliability--based optimization design for kinematic accuracy of shaping mechanism, and acquire the design information accurately and quickly.
