An integrated design method of the compliant linear positioning device (CLPD) was researched, which was composed of a compliant guide mechanism and two electromagnetic actuators. Typically, the actuators are designed after the compliant mechanism, which may make it more complex to improve the performances of the CLPD. With the utilization of the multi-physics co-simulation technology, established a parametric multi-physics finite element model (MFEM) of the CLPD including the compliant linear guide mechanism and the electromagnetic actuators simultaneously in the COMSOL environment. Proposed the constraints of the dominant parameters, based on the analysis of their influence on the characteristics of the CLPD. Then an integrated optimizing design strategy of the CLPD was put forward. According to the strategy, a two degree of freedom long-range linear compliant mechanism and its matching actuators were designed. The experimental results showed the performance of the designed CLPD, which validated the design strategy. |
