探讨指数波响应应用于冲击测量系统的问题。对于线性系统,总的指数波响应时间等于各部件指数波响应时间之和,方波响应时间也有同样的性质。当冲击测量系统在高原下呈现非线性时,Duhamel积分不再适用,建议由指数波响应来代替原来的方波响应。文中计算并给出冲击测量系统和数字仪的指数波响应的允许误差限,判据十分简单。
Exploring the Application of Exponential Wave Response to Impact Measurement System. For a linear system, the total exponential response time equals the sum of the exponential response time of each component, and the square response time has the same properties. Duhamel integrals no longer apply when the impact measurement system is non-linear at high altitude, and it is recommended to replace the original square-wave response with an exponential response. The paper calculates and gives the permissible error limit of the exponential wave response of the impact measurement system and the digital instrument. The criterion is very simple.
