摘要
通过对伺服系统中的功率放大器建立简化模型,对其发热因素进行理论性分析。利用有限元法分别计算了放大器内部零件的发热量,对比试验结果分析影响解析精度的原因,结合实际试验验证了理论的可靠性,总结了散热器的设计方法,从发热量大的案例分析,总结了基板及外壳、风扇的热设计。
By establishing a simplified model of the power amplifier in the servo system,theoretical analysis of its heating factors is carried out in this paper.The finite element method is used to calculate the calorific value of the internal parts of the amplifier;reasons that affect the analytical precision are analyzed by comparing the experimental results.Combining with the actual test,the reliability of the theory is verified,and design methods for the radiator are summarized.Based on the case analysis of high heat emission,thermal design for the substrate,shell and fan is summarized.
