This work is related to the decision of the real engineering task – calculation and constructing of stand for tests on the shock loading holder of knife and bolzen (pin) of industrial mower, producible the machine-building enterprise of “Cigler”. It is set that during exploitation of mowers on the elements of cutting part holder knife and bolzen (pin), loadings of shocks, resulting in their destruction operate. Along with the analysis of reasons destruction and their removal, the task development of stand is formulated for tests on the shock loading holder of knife and bolzen (pin) in the terms of factories. The decision of this task contains the stages: 1. Calculation of sizes of the shock loading at the cyclic loading of holder and bolzen (pin). 2. Theoretical calculation and experimental determination of the destroying loadings for a holder and bolzen (pin). 3. Development of flow and kinematics diagrams of stand, providing the cyclic shock loading in the automatic mode during great while. 4. A theoretical calculation of basic knots of stand is a choice of electric motor, calculation of mechanisms of transmissions, calculation of resilient elements, calculation of parameters of executive part of stand. 5. Development of the program of tests on the shock loading. 6. Making of designer document on a stand is an assembling draft of stand, assembling drafts of basic knots of stand and workings drawings of separate details. Will be drawn on results of calculations and constructing at making of stand.
