摘要
根据消声理论和经验公式,进行了双尾管消声器的设计和开发,利用GT-Power建立发动机模型和消声器模型,并进行了耦合计算。根据尾管噪声和压力损失计算结果,对消声器方案进行性能评价、对比和优化设计,经试验验证,该方案满足设计要求。
Following the theoretic and empirical formula, a double tail pipe muffler was designed and developed.Models of engine and muffler were established with GT-Power, and then were coupled to calculate.Basing on the calculation result of tail pipe noise and pressure loss, performance of muffler schemes was evaluated, compared and optimized.The experiment result shows the schemes satisfy the design requirements.
