Abstract
As one of the key components of the vibration test for airborne products, the quality of the fixture could directly affect the success of the vibration test. In this paper, a sub-regional topology optimization model for the fixture is developed, and two different methods, i.e., an equivalent static-load method and a weighted frequency optimization method, are adopted to establish the mathematical formula for the optimization. Based on the results that similar structural configurations are obtained by the two methods, a new fixture structure is designed with 30% weight being reduced as compared to the original one. Meanwhile, the feasibility of the proposed method is further verified by the modal analysis and the random vibration analysis. As a result, the first few natural frequencies of the new fixture have a great degree of improvement by comparing with those of the original structure. In addition, the dynamic response at the connection point with the test sample, i.e., the root mean square (RMS) of the acceleration, has a significant decrease. The method in this paper could provide a valuable tool for the dynamic design of other structures.
