Design of sprayer boom suspensions through computer simulation and design optimization

Control of the movement of the field sprayer boom will directly enhance uniform deposition of chemicals. Means are necessary to insure that the boom structure supporting the spray applicators follows low frequency ground slope changes and to insure attenuation of high frequency signals from the sprayer boom. Suspensions between the sprayer boom and the sprayer improve control of boom movement. The suspension designs analyzed in this study include: central pivot, simple pendulum, double pendulum, and twin-link. The suspension models derived for this study consisted of two-dimensional roll models for analysis of the vertical movement of the sprayer boom in relation to the input excitation to the suspension system. The design procedure developed for use on personal computers combines existing optimization and dynamic simulation codes to measure suspension performance and to determine design parameters that improve suspension performance. The designer specifies the input excitation to the suspension system and the desired performance criteria that define overall suspension performance.
