In the ADAMS, the dynamic characteristics of the high-speed machine tool in the case of uniform acceleration and variable acceleration are analyzed by the acceleration variation law indicated by -1,3-2, and the output curve visually reflects the change. law. The establishment of the dynamics simulation model In the dynamic analysis, the inertial characteristics of the object are important parameters affecting the system. For those parts with small inertia and negligible, the definition of the crop body is not available. The driving force is added to the moving pair in the original X and Y directions to simulate the dynamic characteristics of each moving part in the machining center, thus completing the definition of components, constraints, and forces. After the driving is applied, the acceleration, velocity and displacement of each moving member are the same as those of the above kinematic analysis, and will not be described again here. The following is mainly to analyze the change of the instantaneous driving force of the linear motor at the moment of starting in both the constant speed and the variable acceleration. The dynamic analysis of mechanical system is to discuss the relationship between load and system motion. In the high-speed machine tool studied in this paper, the motion law of two linear directions is known, and the driving force needs to be determined. Since the friction factor is considered in the kinetic analysis section, the driving force is used to provide the inertial force against the frictional resistance. The magnitude of the driving force is the algebraic sum of the inertial force and the frictional resistance. The X-direction dynamics simulation analysis under two kinds of accelerations compares the acceleration changes in the X direction in the range of t=00.15s when the uniform acceleration and the variable acceleration are compared. When the X-direction starting force is accelerated and the acceleration is accelerated during the acceleration, the speed change in the range of t=00.15 s in the X direction is as shown by -6 and 4-7. It can be seen from the above figure that when the acceleration is uniform, the X-direction driving force has a mutation at t=0s and t=0.08s; when the acceleration is accelerated, the X-direction driving force has no mutation at t=0s and t=0.08s. It can be seen that when the acceleration is uniform, the acceleration and driving force in the X direction increase to 12500m/s2 and 71575.5736N at the moment when the moving parts are stationary, and the static instantaneous impact force is large, which has a bad influence on the structure and precision of the machine tool; When the acceleration and driving force in the X direction are both zero, the acceleration and the driving force are gradually increased during the movement, although the maximum acceleration and the maximum driving force at the time of the acceleration are larger than that at the time of uniform acceleration, but since it is in the motion process It is achieved in the middle, so there is no static impact on the machine tool, and it will not have a bad influence on the structure and precision of the machine tool. The Y-direction dynamics simulation analysis of the two accelerations compares the Y-direction dynamics simulation analysis of the two accelerations with the X-direction comparison results. The acceleration in the Y direction is uniform acceleration and acceleration. The Y-direction start at the time of uniform acceleration and the Y-direction start-up force at the acceleration acceleration and acceleration at the Y-direction of the acceleration of 3-6 acceleration. There is no sudden change in acceleration when the acceleration is accelerated, so that there is no sudden change in the driving force. Moreover, since the static impact force during the acceleration is small, the influence on the structure and precision of the machine tool is much smaller than that of the uniform acceleration, and the performance of the machine tool is improved. Since the starting force in the Y direction is transmitted to the X-direction rail through the slider on the beam, the change in the Y-direction starting force affects the performance of the X-direction rail. Summarizing the high acceleration required for high-speed machine tools, high driving force is required at start-up, and the moving parts are stationary at the moment of starting, so there is a high static impact. By using sinusoidal acceleration, the starting acceleration of the moving parts becomes zero, which greatly reduces the starting force and improves the adverse effects of instantaneous static impact on the machine structure, life and accuracy.
