In order to satisfy the requirements of the high reliability of electric control unit (ECU) of the Diesel Engine, the thermal analysis of ECU was performed by using the software FLOTHERM based on the finite volume method. The temperature field of ECU was obtained under different operating conditions. The structural optimization of ECU was completed to solve the problem of local high temperature. As a result, the operational temperature of ECU is reduced under the allowable limit, and its reliability is improved. The physical experiment shows that the thermal analysis and structural optimization are valid. The local high temperature could be reduced effectively and the operational reliability is improved.

Bimorph Thermal Actuator

Micro-actuator is the key device for the MEMS to perform physical functions. According to a kind of bimorph thermal actuator, this article presents an optimum design method to improve the sensitivity of MEMS actuator. Based on thermal analysis of software ANSYS, the thermal displacement and distribution of temperature field can be obtained clearly. Then a series of reasonable parameters are determined by optimum calculation.

Shim Coil

It is necessary to develop a high homogeneous, low power consumption, high frequency and small-size shim coil for high precision and low-cost atomic spin gyroscope (ASG). To provide the shim coil, a multi-objective optimization design method is proposed. All structural parameters including the wire diameter are optimized. In addition to the homogeneity, the size of optimized coil, especially the axial position and winding number, is restricted to develop the small-size shim coil with low power consumption. The 0-1 linear programming is adopted in the optimal model to conveniently describe winding distributions. The branch and bound algorithm is used to solve this model. Theoretical optimization results show that the homogeneity of the optimized shim coil is several orders of magnitudes better than the same-size solenoid. A simulation experiment is also conducted. Experimental results show that optimization results are verified, and power consumption of the optimized coil is about half of the solenoid when providing the same uniform magnetic field. This indicates that the proposed optimal method is feasible to develop shim coil for ASG.
