Tidal forces produced by black holes are an important result of General Relativity related to the spacetime curvature tensor. Among the astrophysical implications of tidal forces, the tidal disruption events stand out. We analyze the tidal forces in the spacetime of an electrically charged Hayward regular black hole, obtaining the components of the tidal tensor and the geodesic deviation equation. We find that the radial and angular tidal forces may vanish and change sign unlike in the Schwarzschild spacetime. We note that tidal forces are finite at the origin of the radial coordinate in this regular black hole spacetime. We obtain the geodesic deviation vector for a body constituted of dust infalling towards the black hole with two different initial conditions.

带电海沃德黑洞时空中的潮汐力

黑洞产生的潮汐力是广义相对论与时空曲率张量相关的重要结果。在潮汐力的天体物理学影响中，潮汐破坏事件最为突出。我们分析了带电海沃德规则黑洞时空中的潮汐力，获得了潮汐张量的分量和测地线偏差方程。我们发现，与史瓦西时空不同，径向和角潮汐力可能会消失并改变符号。我们注意到潮汐力在这个常规黑洞时空中的径向坐标原点是有限的。我们获得了由两个不同初始条件下落入黑洞的尘埃构成的物体的测地线偏差矢量。
