The analytic approach of finite element was adopted to carry on the modal and random vibration analysis for the main pipeline of a watering cart.The results indicate the first five orders of modal frequency are within the range of spectrum excitation,and the dynamic characteristics are bad.By using simulation method the automobile responses under road excitation was regarded as the inputs of vibration analysis.Random vibration analysis indicates the system produces greater dynamic responses while the frequency of excitation is 24Hz.
