the article analyzes the forces that arise in the carriage and suspension by the example of a motorcycle. There is the determination of forces that arise in the carriage and suspension in the early stages of design. The algorithm is proposed to be used to determine the forces. This algorithm is based on the program writing in the programming language Python. Input data for the determination of forces are geometric dimensions of a vehicle, weight of a vehicle, characteristics of a ground and a

Ельцина, г. Екатеринбург Аннотация: в статье анализируются реакции в узлах конструкций несущих систем и направляющего устройства подвески на примере мотоцикла. Рассматривается метод определения реакций в узлах конструкций несущих систем и направляющего устройства подвески на ранних этапах проектирования. Для определения реакции предлагается воспользоваться алгоритмом, на основе которого в качестве примера написана программа на языке программирования Python. Исходными данными для определения являются геометрические размеры транспортного средства, масса транспортного средства, характеристики опорной поверхности и режима движения транспортного средства. Ключевые слова: подвеска, несущая система, несущая система, определение сил, мотоцикл, Python 2.7. Arising in the carriage and suspension forces, geometric dimensions and weights of elements or the entire vehicle must be determined for making the strength test of vehicle and selecting the section that will be arisen by these forces. The strength calculation can be made only after these actions. In the initial stages of the design of vehicles, we face the problem with lacking of information to select the section for making design calculations. Approximate geometric dimensions, places of fastening parts of the vehicle and the characteristic points with the suspension are known in their initial design but it does not allow making full calculations. The existing methods of calculation were based on the CAD / CAE-systems that require a high power of the computing machinery, a large amount of input data (for example, 3D model), the ability of creating the correct constructions of 3D models and making the CAE calculations. However, it takes a lot of time. The way of solving the problem is using the program writing in the programming language Python [1].This program helps to determine the force that arise in the carriage and suspension. This program includes the algorithm for determine the forces from the elements of the carriage by solving a system of linear equations. This is the following information that needs to be known for making the program:  Geometric dimensions of a vehicle, carriage and suspension;  Mass of a vehicle or of all elements of a vehicle;
