Numerical simulation by Matlab for the new hypocycloid energy transformation mechanisms was done by means of the four-order Runge-kutta's method. The result shows that the simple harmonic and rectilinear motion of piston in the new mechanism make the engine working more stable. The peak acceleration is around 25% lower in the new mechanism than that in the conventional slider-crank mechanism. And the output speed is much higher at the same identical mean effective pressure and same load torque. And then the output power of the engine is improved.

In combination with sensitivity analysis, it is found that the main reason causing the fuse failure in bore is the lateral shock between the bourrelet and the bore surface. This shock produce huge lateral impulsive force and acceleration causing fuse mechanism plastic deformation and improper function. Besides, it may lead to fall-off in fuse safety.

造成引信瞎火的主要原因是由于弹丸在膛内运动期间，弹丸与身管内壁间的相互碰撞所产生的横向冲击加速度使引信保险机构产生多次重复振荡，使其产生局部塑性变形及破坏不能可靠解除保险所致；并可能导致引信膛内安全性下降。

The method combines the inverse dynamics control with the ZMP-plane acceleration projection, whereby the whole body stability of the robot can be considered simultaneously when tracking the predefined trajectories. With this method, the inapplicability existing in the classical control methods in the terms of disturbance rejection and stability maintenance is solved.4 Finally, in order to verify the proposed methods, experiment platforms for the motion planning and disturbance rejection control are constructed respectively.

There is therefore no possibility of gerbilling due to incautious acceleration; but it could still happen when you try to brake.

因此，有没有可能gerbilling由于不谨慎加速度；但它仍然可以发生，当您尝试制动。

Pressure characteristics and condition of cavitation incipience were analyzed.

在沿固体表面法线方向减速运动阶段，由于液体离开固体表面的惯性使得液体与固壁面间产生低压，当固体表面运动加速度超过某个临界值时，液体因压力低于空化临界压力而发生空化，空化与固体表面结构及液体流动特性有关。

This kind of sensor can be used to measure the angle of the inclined plane and the acceleration .
