摘要
为研究梳栉自身的固有性质与力学性能,提高梳栉在经编机横移运动中的平稳性与动态响应性,对梳栉横移机构进行简化分析并建立动力学模型。根据牛顿运动定律给出动力学微分方程,用拉普拉斯变换法进行求解,并应用MatLab/Simulink仿真分析模块创建了相应的仿真模型。采用声学与振动分析系统(3560C型)、4507B型加速度传感器和电脑组成的振动测试系统对梳栉进行实际采点测量,以实测梳栉外部激励作为输入信号对模型进行了仿真,仿真所得振动加速度响应与实测结果吻合程度较高,证明该模型的建立是成功的。
In order to research the inherent nature and mechanical property of the guide bar and improve its stability and dynamic response during shogging motion,this study makes a simplified analysis of the shogging mechanism and establishes a dynamic model.The dynamic differential equation is given according to the theory of Newton′s laws of motion and finds the solution by Laplace transform equation.A corresponding simulation model is developed based on MatLab/Simulink analysis module.Point-by-point measurement of the guide bar is conducted with a vibration test system which consists of a analytical system of acoustics and vibration（model 3560C）,an acceleration transducer（model 4507B） and a computer.Simulation was executed using the measured external incentives data of the guide bar as the input signal,and the simulated vibration acceleration response curve is identified with the test result,which verifies the correctness of the model.
